Schmersal launches two new safety modules: the safety relay module SRB-E-302ST and the output expansion SRB-E-402EM are efficient and space-saving solutions for safe signal evaluation.

One evaluation unit for two safety sensors: the most striking feature of the SRB-E-302ST safety relay module, with which Schmersal will replace several modules in the outdated AES series. The module enables monitoring of all common electromechanical and electronic safety switches and safety sensors, as well as active opto-electronic protective devices (AOPDs). Depending on the application, the module switches with the fail-safe relay contacts or wear-free with a fail-safe semiconductor output. The module allows the realisation of applications up to category 4/PL e (EN ISO 13849-1) as well as SIL 3 (IEC 61508).

The new series gives the electrical designer scope to save space in the switch cabinet and reduce costs, while at the same time utilising the full functionality of a state-of-the-art safety module twice over. Control is either single-channel or dual-channel and the module comes with functions including stop 0, autostart and reset with edge monitoring, plus the option to select from 24 pre-configured applications with a rotary switch. The user can select the start function with a second rotary switch.

Also new is the SRB-E-402EM output expansion, which, like the SRB-E-302ST, is accommodated in a modern and compact housing from the SRB-E series. The output expansion allows designers to duplicate and reinforce the contacts of fail-safe relays and semiconductor outputs. Four safety contacts, two signalling contacts and feedback contacts are available. The new safety module can be used as an expansion module for all safety modules and safety controllers with feedback loop monitoring. When compared to the predecessor series, the new module is characterised by more compact dimensions and an increased temperature range (-25°C to +60°C).

Schmersal launches respiratory protection mask to FFP2 standard /en/press/press-releases/detail/schmersal-launches-respiratory-protection-mask-to-ffp2-standard-8884 Reusable protective equipment for infection prevention and occupational safety Wuppertal, 20 October 2021. The Schmersal Group has developed a particle-filtering half-face mask without exhalation valve. The reusable SPM100 respiratory protection mask satisfies the requirements of EN 149:2001+A1+2009 FFP2 and is available for delivery as of now. The mask is designed to reliably protect medical staff and employees at other exposed work locations, for example dusty work environments, from solid and liquid aerosols.

The mask body in the SPM100 (Schmersal Protection Mask) is made from medical-grade, biocompatible polypropylene (PP) and is reusable. The mask seal is created with a silicone profile that can be removed easily for regular disinfection and then quickly be reinserted into the mask. The filter caps can be removed with ease, thus offering easy filter changes. All reusable parts of the mask are made from resistant materials that are suitable for cleaning and disinfection.

The SPM100 respiratory protection mask is used with an FFP2 filter insert, PPE category III, in order to prevent the inhalation and/or transfer of particles, droplets and aerosols. This filter unit filters certain particles from the air inhaled by the wearer within the specified limit values of the filter used.

The SPM100 is a respiratory protection mask with no exhalation valve. Respiratory protection masks without an exhalation valve protect the wearer and prevent the wearer from contaminating his or her surroundings with exhaled droplets. In addition, the mask also comprises skin-compatible components and offers maximum comfort for the wearer.

‘In developing the SPM100 respiratory protection mask, we made full use of our many years of experience in safety technology and occupational safety. We want to help ensure that even in this difficult time of the coronavirus people can work safely and stay healthy,’ explains Matthias Banaszek, Project Manager for Strategic Organisation Development.

Other products and services for infection prevention
In addition to the SPM100 respiratory protection mask, the Schmersal Group offers other products and services to help protect employees from coronavirus infection in the working environment. This includes ‘Schmersal Access Control’ (SAC-IO-20), which enables digital organisation of access management by limiting visitors, e.g. in retail settings. The system is an intuitive traffic light system with integrated counter that automatically counts the number of visitors entering a shop or other facility.
In addition, tec.nicum, Schmersal’s service division, offers execution and documentation of ‘Risk assessments for infection prevention’ for businesses in all industries – a legal requirement for employers under industrial health and safety regulation and fully independent of a current coronavirus pandemic.

Schmersal at SPS ‘Smart Production Solutions’ 2021  /en/press/press-releases/detail/schmersal-at-sps-smart-production-solutions-2021-8862 New solutions for the safety of machinery – compact, digital, networked Wuppertal, 11 October 2021. ‘Compact, digital, networked’ is the Schmersal Group’s motto for the upcoming SPS ‘Smart Production Solutions’ 2021 in Nuremberg, Germany, at which the Group will be showcasing new solutions for the safety of machinery designed to achieve maximum effect with minimum effort. Reducing the size of safety components means a reduction in material expenditure and in the installation space required in machinery and systems. Continuing digital advancement, even in safety systems, means greater process transparency and predictive maintenance concepts. With Industry 4.0, machinery and systems are becoming increasingly complex, which means a need for more comprehensive safety systems. The networking of different safety switchgear devices is one way of reducing the complexity. 
At Stand 460, Hall 9, Schmersal will be demonstrating how the challenges presented by Industry 4.0 can be tackled through miniaturisation, digitisation and networking of safety components and systems.

Miniaturisation – a smart switch in mini format
The AZM40 is the smallest electronic safety interlock in the world, with a holding force of 2000 Newtons. With great angle flexibility, the interlock can easily fit into confined spaces and those areas that are difficult to access.
Similarly compact is the RSS260 RFID safety sensor – Schmersal has now equipped the sensor with new software, giving it four additional features, which can be selected as required. The additional features of the RSS260 not only make it possible to save on a safety relay module, but they also reduce the wiring and installation effort.

Digitisation – Schmersal presents new safety controller for the first time
One of the key features of digital production is a continuous exchange of data. With the PROTECT PSC1 safety controller, the user can utilise the integrated universal communication interface as a gateway to transmit diagnostics information from the safety sensors to a higher-level control system. In addition, the user can also take advantage of the modular, programmable safety controller to easily implement safety requirements for different machinery in a way that is specifically targeted.
Schmersal will also be using SPS 2021 to present for the first time the successor to the PROTECT PSC1, with its range of additional features.

Networking – greater flexibility with reduced wiring effort
Schmersal has a number of solutions designed to help master increasingly complex safety measures for larger machinery and systems. The Safety Fieldbox enables flexible and individually configurable safety solutions as well as fail-safe plug and play installation of a divergent range of switches. 
The SD bus from Schmersal is a system designed for serial diagnosis of series circuits. Combined with the new PSC1 safety controller solution from Schmersal, with OPC UA connection, it turns the serial bus into SD 4.0, thus enabling development of Industry 4.0-capable safety concepts with maximum design convenience and ease of scalability.

Safety at the Schmersal stand
In view of the ongoing risk of coronavirus, Schmersal has developed a strict hygiene concept for its stand at 460, Hall 9 to help protect the health and safety of stand visitors.

Visit Schmersal at SPS 2021 – Smart Production Solutions – in Nuremberg, Germany, between 23 and 25/11/2021: Stand 460, Hall 9.

Versatile and now also explosion-safe /en/press/press-releases/detail/versatile-and-now-also-explosion-safe-8811 New heavy-duty switches for potentially explosive applications Wuppertal, 23 August 2021. The Schmersal Group have expanded their existing range of switches for heavy industry to include explosion-proof variants that are suitable for use in areas at risk of explosion. The pull-wire emergency switches in the EX-I-ZQ900 and EX-I-RS655 series as well as the belt misalignment switches in the EX-I-BS655 and EX-T. 454 series can be used in dusty environments in Zone 21 in ignition protection class Ex tb ‘Protection by enclosure’ or in gas atmospheres in Zone 1 in ignition protection class Ex ib ‘Intrinsic safety’.

The new versions expand the possible range of applications for these switches:
The variants certified for Zone 1 have been designed for applications in which hazardous gases could occur, such as in the chemicals and petrochemical industry as well as in refineries, landfill sites and recycling plants. 
Switches that are certified for Zone 21 are suitable for areas outside of dust-enclosing containers, such as near to filling and removal points, conveyor belts or HGV dumping points, such as those found in recycling plants, gravel and cement works, thermal power plants and in the metalworking industry.

Pull-wire emergency switches for safe and reliable shutdown
The EX-I-ZQ900 pull-wire emergency switch with single-sided action is used on machines and systems in areas at risk of explosion, where there might the need to trigger the emergency stop command at any point along the route of the wire. With a wire length of up to 75 m, it offers numerous contact combinations for a safe and reliable shutdown as well as simple, quick diagnosis.
For greater distances, there is the EX-I-RS655 pull-wire emergency switch with two-sided action. The main characteristic is a significantly reduced installation cost, made possible by the wire length of up to 2x 100 m as well as by the central connection terminal. The central connection terminal enables quick and easy wiring. The EX-I-RS655 with integrated DuplineSafe interface for safe series connection, including diagnostics, is available as an option. 

Belt misalignment monitoring
Belt misalignment switches in the EX-T.454 and EX-I-BS655 series, made of grey cast iron, monitor the straight alignment of conveyor systems and are arranged in pairs on both sides of the belt, close to the drive pulleys and idlers.
Uneven loads can cause position deviations, which in extreme cases can cause damage and material spillage. A staggered signal for position monitoring enables prompt belt correction with the pre-warning signal, while a stop signal will cause the conveyor system to be shut down. 

The EX-I-BS655 series is based on the multifunctional HDS product platform. With a basic switch and a range of actuating elements as well as different roller diameters and adjustable switching angles, it can be flexibly adapted to the conveyor system in question. Connection to the pre-assembled connection terminal is extremely simple. 
Both the EX-T.454 and the EX-I-BS655 are available with the optional Dupline fieldbus interface, which offers greater diagnostic convenience with reduced wiring effort. 

The Ex switchgear is constructed in accordance with the requirements of the ATEX Directive 2014/34/EU. With IECEx approval, the switchgear also meets international explosion protection requirements.

RSS260 safety sensor with new cost-saving features /en/press/press-releases/detail/rss260-safety-sensor-with-new-cost-saving-features-8797 Integrated software logic enables efficient safety solutions Wuppertal, 30 July 2021. The Schmersal Group has further developed its compact RSS260 safety sensor and equipped it with new software – the sensor now offers four additional, optionally selectable functions:

  • Feedback loop monitoring
  • Automatic restart / manual restart
  • Reset
  • Emergency stop monitoring

On the F0/F1 version, the RSS260 assumes the tasks of a safety relay module, i.e. monitoring of the movable safety guard as well as of the contactors directly actuated by the sensor outputs – monitoring is carried out by the integrated logic in the sensor, rendering a separate evaluation device unnecessary.  

On the F0 version, the machine restarts automatically as soon as all safety guards have been closed. An additional ‘enable button’, without edge monitoring, can be switched into the feedback loop. The F0 version is suitable for small machines without a protective space that can be accessed behind.
The F1 version is recommended for smaller systems, where the hazardous area can be accessed by the operator, as it has a reset function. The edge-monitored reset button must be pressed before the machine is restarted – when it is clear that the system is in a safe state and that no one is in the hazardous area. This function is consistent with the ‘manual reset function’ in accordance with EN ISO 13849-1.

The RSS260 with Q function is suitable for machines where the use of an EMERGENCY STOP switch is compulsory. EMERGENCY STOP switching elements integrated into a series circuit can be monitored by the Q function in the last sensor of the chain. This eliminates the need to install a separate safety circuit for the EMERGENCY STOP switches. The EMERGENCY STOP switching elements monitored by the Q function meet the requirements up to PL e. A reset button is required here as well, as no automatic restart of the machine is permitted after an EMERGENCY STOP command has been reset.

‘The additional features of the RSS260 not only make it possible to save on a safety relay module, but they also reduce the wiring and installation effort. What’s more, the Q variant does not require a separate safety circuit for the EMERGENCY STOP,’ explains Uwe Richter, Product Manager for Safety Technology, summarising the benefits of the new software.

Additionally, the RFID safety sensor offers a number of positives, even in the standard version: with its compact dimensions (40 x 18 x 30 mm), the RSS260 with matching sensor-target combination is suitable for mounting on aluminium profiles as well as for use on many other door formats such as the common perspex doors and panels. The sensor has both an AS-i-Safety-at-Work interface and an interface for the Schmersal SD bus. The serial diagnostic function (SD) enables series connection of up to 31 safety sensors and solenoid interlocks, as well as the transmission of non-safe diagnostic and status data for the connected devices.

Ready for the US market— new AZM40 solenoid interlock with UL certification /en/press/press-releases/detail/ready-for-the-us-market-new-azm40-solenoid-interlock-with-ul-certification-8273 Smallest electronic solenoid interlock in the world Wuppertal, 17 May 2021. The new compact AZM40 solenoid interlock now has UL certification, which means that it can be used in machinery and systems intended for the North American market. In addition, Schmersal has optimised the interlock as well as developed additional versions that incorporate specific customer requirements. 

The new development has generated considerable market interest thanks to its compact ‘on-trend’ dimensions. With dimensions of 119.5 x 40 x 20 mm, the AZM40 is the smallest electronic solenoid interlock in the world. The AZM40 is the ideal safety solution for all machine builders looking for optimisation through miniaturisation, simplification and minimisation of materials. 

The compact AZM40 can also be installed easily in confined and hard-to-access areas thanks to 180° angular flexibility of the actuator. An added benefit is its universal use on rotary and sliding doors with a single design version.

New enclosure versions
The AZM40 solenoid interlock and actuator are available in two enclosure versions. For typical use in mechanical engineering, there are enclosures with a flat, screw-on surface for cylinder-head bolts. For visually improved installation and where space saving is a priority, there is a version with countersunk tapers for countersunk bolts.

Low-energy safety solution
The AZM40 operates to a bistable holding principle. This means that it maintains its locking position and securely holds the guard door in the event of power failure, thereby preventing hazardous run-on movements. In addition, energy consumption with the bistable principle is lower.

New safety module for sensorless standstill detection of drive systems   /en/press/press-releases/detail/new-safety-module-for-sensorless-standstill-detection-of-drive-systems-8148 Universal – compact design  Wuppertal, 20 January 2021. If a machine or system is expected to produce potentially hazardous overtravel movements, a combination of safety interlock on the guard and standstill monitor in the switch cabinet can provide the requisite level of safety. The SSW303HV is the Schmersal Group's latest sensorless standstill monitor, offering a significant improvement over its AZR and FWS series predecessors.

A key development goal was universal application of the new standstill monitor, which in total replaces fourteen variants of the previous product range. This is made possible thanks to use of a wide-range power supply for all common AC and DC operating voltages, from 24 V/DC / 24 V/AC to 230 V/AC. The increased temperature range of -25 to +55°C also opens up additional application potential.
A further benefit is its compact design – the SSW303HV takes up just 45 mm of structural width in the switch cabinet. The pluggable, coded connecting terminals ensure rapid, error-free installation, while an additional signalling contact provides information on the error status of the module.

As the standstill monitor operates entirely without sensors, the machine builder no longer needs to intervene with the ‘hardware’ of the surrounding structure. The safety module is connected directly to a three-phase motor and directly measures the frequency of the induced voltage, at rated motor voltages of up to 690 V. The safety contacts for releasing the locking mechanism close as soon as the motor comes to a standstill.
The SSW303HV can be used in safety circuits up to category 4/Performance Level e in accordance with EN 13849-1 and SIL 3 in accordance with EN IEC 61508, with all typical safety interlock designs from applicable manufacturers.

Digital access control system for the retail trade /en/press/press-releases/detail/digital-access-control-system-for-the-retail-trade-8083 New solution makes it easier to maintain 20 m2 limit Wuppertal, Germany, 1 December 2020.  Following the new German Federal/State resolutions of 25 November 2020 designed to contain the coronavirus, retail businesses with an area of more than 800 m2 will be permitted to allow only one-person entry for every 20 m2 of space. For smaller businesses, the limit is one customer for every 10 m2 of retail space. The new digital access control system from Schmersal makes it easier for retail businesses to adhere to the tighter coronavirus rules without the need for major staff increases. 

To be able to maintain the limit, access management is absolutely essential. ‘Schmersal Access Control’ (SAC-IO-20) is an intuitive traffic-light system with integrated counter that automatically counts the number of visitors entering a building. As soon as a maximum number of visitors has entered, a signal tone is sounded to indicate that the person who entered the building last must leave. In addition, the access possibilities are signalled by traffic light colours: with green meaning ‘please enter’ and red meaning ‘please wait’.  The system has already been successfully tested in the retail industry. 

Key elements of the system are an indicator light (green, yellow, red) with buzzer and a programmable safety relay module from the PROTECT SRB-E series from Schmersal. This module is normally used to monitor safety switchgear and achieves the maximum safety level in machine safety. 
The traffic-light system is quick and easy to install, requiring just a conventional 230 V socket; the counter also needs to be set. The system offers a standard version for up to 20 people, while versions for up to 200 people are available, and comprises industry-tested components. For user-friendly operation, the system incorporates command devices from the Schmersal N range, which are designed for maximum hygiene and easy cleaning.

 ‘Many businesses have developed creative makeshift solutions for access management, but they often require considerable staffing or in many cases even raise the risk of contagion,’ explains Ulrich Bernhardt, Sales Manager for Control Systems at the Schmersal Group. ‘By contrast, Schmersal Access Control is a simple system that can be operated with very little investment and few staff. We have put our experience in safety systems into the development of the system. For decades, Schmersal has been working to ensure that people are protected from health hazards in their working environment.’
