Leading Manufacturer of Safety Interlock Switches and Machine Guard Safety Switch Devices for Automation and Process Safety

Solenoid Controlled RFID Safety Interlock Switches with OSSD (Stainless Steel)

The Z-Range RFID coded solenoid guard locking safety switches have been designed as a robust position interlock for detection of moving guards, providing a lock mechanism to keep the guard closed until the hazard has been removed. The integrated RFID coding creates a high level of anti-tamper that cannot be defeated or by-passed.

The Z-Range will connect to most OSSD compatible safety relays and combines internal self-monitoring with High Coded RFID (Type 4 to EN14119), achieving PLe/CAT4 safety level (ISO 13849-1), even when connected in series (up to 30 units).

The head of the switch features a highly reliable anti-tamper cam system with RFID sensing on two entry points, suitable for fitting to the leading edge of sliding or hinged machine guards. This combination of technologies achieves the highest level of functional safety and coding available. The head can rotate to provide up to 8 actuator entry positions for full flexibility when mounting.

For the harsh environments like Food Processing, Pharmaceutical and Petro-Chemical Industries the Stainless Steel 316 range offers protection up to IP69K for use in high pressure chemical cleaning or CIP/SIP applications. The IP69K enclosure protection (maintained by a double seal lid gasket) and can be high pressure hosed with detergent up to +80C and 100psi.
