EC: RSS36 noncontact electronic sensor with RFID
Safety – Machine safety: The RSS36 is a noncontact electronic sensor from Schmersal that uses enhanced RFID technology to test the closed position of hinged, sliding, or removable machine guard doors in PL-e or SIL3 safety systems. This is a Control Engineering 2012 Engineers’ Choice finalist.
Schmersal’s RSS36 noncontact electronic safety sensor is designed for safety circuits and is used for monitoring the position of movable safety guards. In various applications, the RSS36 monitors the closed position of hinged, sliding, or removable guards with the aid of a coded actuator target. The RSS36 is designed to meet stringent North American and European standards, is cUL and CE approved, and can be used in the highest level of machine safety circuits, PL-e per ISO13849-1 and SIL 3 per IEC61508. The RSS36 sensors offer IP69K ingress protection rating and are ECOLAB tested.
The RSS36 sensors use an enhanced RFID technology for the data exchange with their actuator target. This provides an increased EMC immunity, eliminating the need for shielded cables. There are three different coding variants available, providing the appropriate level of protection against tampering for each application. A built-in magnetic latch is available for the RSS36, offering a holding force of approximately 5 lbs. This feature is unique to sensors of this type; typically noncontact sensors would require a secondary latch to hold a safety guard closed. In applications where the magnetic latch of the RSS is employed, the sensor can be used as a door stop.
The RSS36 series complements Schmersal’s patented pulse-echo family of safety sensors. The RSS36 can be connected in series or in combination with pulse-echo sensors and locking switches, up to 31 devices, without loss of signal or safety level and monitored with a number of standard safety controllers. The RSS36 integrated LED displays operation status at the guard location. Serial diagnostics are also available with the RSS36, allowing information to be communicated via a universal gateway compatible with several automation platforms. The RSS36 sensors provide intelligent diagnostics and fast error detection, and reduced wiring, and helps minimize machine downtime.
