Schmersal Newsletter

Welcome to the Newsletter Issue 02-2015

Ladies and Gentlemen,

The Schmersal Group is introducing new technology with a familiar design:

Safety sensor RSS 16 with RFID technology with improved protection against manipulation

 

The RSS 16 RFID safety sensor has a similar design and the same dimensions as the classic among safety switches. However, unlike the AZ 16, the RSS 16 does not have a mechanical actuator. Instead, targets are identified on a non-contact basis using the RSS technology developed by Schmersal. A technical safety modified RFID signal is responsible for communication between the transmitter and receiver.

Meets stricter requirements in terms of manipulation protection

The RFID technology allows increased manipulation protection thanks to various code variants:
users of the RSS 16 can select from three different code variants. In the basic version the sensor accepts every suitable target. A second version only accepts the target it was taught about when it was first switched on. Finally, a third version is available, in which the teaching process can be repeated any number of times.  This considerably improved manipulation protection is of real benefit right now, as Paragraph 6 of the operational safety ordinance, which comes into force on 01 June 2015, stipulates that "the employer must ensure that (...) safety devices cannot be manipulated or bypassed." The RSS 16, which is individually coded to coding level "high" in accordance with ISO 14119, already meets this requirement perfectly.

Adapts to different installation scenarios

As with the AZ 16, with the RSS 16, the target can be approached from three sides, which means that the
RSS 16 can easily be integrated into a  wide range of installation scenarios.  This allows a range of applications.

Here are three typical installation scenarios:

Frontale Betätigung

Front actuation - plexiglas door:
no disruptive lines from flat actuator.

Bodenseitige Betätigung

Bottom actuation - with soft-close door catch and 40 N magnetic catch.

Seitliche Betätigung

Side actuation - sliding door, can be approached from all angles

Can be used as a door catch

The non-contact principle allows excellent tolerance to door offset and, unlike the mechanical solution, allows an actuation direction to the side of the sensor area. Alternatively, the safety sensor can also be used as a magnetic catch so that the design engineer does not need a separate stop and latch and can use the RSS 16 as a door stop with latching force of up to 60 N.

Suitable for series connection

The safety signals can be combined with other electronic safety switchgear in series to produce a security analysis. The installation benefits include the connection options for fitted connections or the terminal connection space with four connection openings. This means that, with series connection, the cable layout can be designed to fit perfectly and adapted to the geometry of the individual machine.

Benefits at a glance:

  • "High" coding level as per ISO 14119 thanks to individual RFID code
  • Three coding variants for manipulation protection as required
  • Three actuation directions
  • Door catch with magnetic catch function
  • Terminal space for plug connection
  • Also suitable for series connection
    - up to PL e / Category 4 in accordance with ISO 13849-1
    - in SIL 3 as per IEC 61508

The new safety sensor can be be used as a 1:1 replacement for the AZ 16 in existing designs.

Video shows the benefits of the RSS 16 in action

Our video animation clearly explains the basic functions and simple installation of the RSS 16. The code variants which ensure increased manipulation protection are also shown, as is the increased operational safety and system availability guaranteed, for example, by the greater tolerance range on door offset and the controlled switch-off process for cross-circuits.
