Pulse Echo Based Solenoid Interlock

Schmersal Inc.

The AZM200 is an electronic solenoid interlock  for cells where access to hazardous work areas must be controlled until a safe condition exist. Its door handle actuator is available with an optional inside emergency release handle which mechanically overrides the solenoid lock from inside the hazardous area, allowing operators to leave quickly and safely – even during a power failure. Dual microprocessors provides continuous internal function tests and monitors the door detection sensor and actuator to assure that the guard is closed and locked, meeting both the R15.06 requirements and PLe to ISO13849-1 and SIL 3 to IEC61508, even when wired in series. Serial diagnostics is also available to connect to various commercial field bus systems.
