Safety interlock switch is tamper-resistant
Ensuring long-term reliability in hostile environments is not the only challenge facing machine safety systems: providing a high degree of resistance to tampering helps to prevent the unauthorised overriding of safety interlocks and is also an important aspect of maintaining system integrity.
The latest safety interlock switch from Scientific Technologies Inc (STI) is designed with both security and longevity in mind. The new MFS standalone safety interlock switch requires both magnetic and ferro-resonant signals to close the safety signalsmaking it highly resistant to tampering and yet reliable in operation. In lower-risk applications it can be used as a standalone safety switchand is capable of direct switching relays and contactors up to 2A at 230 V ac. For applications that require a higher degree of safety integritythe MFS can be coupled with safety-monitoring relays for added security. A visible indication of the switch’s status is provided by a built-in LED indicator.
A Nema 6 (IP 67) rated housing makes the MFS water resistant and suitable for use in water wash-down environments.
