Product Details

Schmersal EX-AZM161 Solenoid Interlock Switch, Explosion Proof

The EX-AZM161 is a solenoid interlock switch designed for explosives atmospheres. It will ensure that sliding, hinged and removable guarding devices cannot be opened until hazardous conditions have come to an end (when used in combination with the control elements of a machine, e.g. fail-safe standstill monitors or fail-safe delay timers). They are also used for cases in which the opening of a guarding device represents a non-permissible intrusion in a production process.
The switching element with interlock on the EX-AZM161 is not physically connected to the actuator but functionally brought together or separated on switching. When the guard device is opened in the uninterlocked condition, the actuator is separated from the base unit. In the process, NC contacts are positively opened and NO contacts closed.
Interlocking is carried out by means of a latching bolt which blocks the actuator so that it cannot be withdrawn from the interlock. The machine control circuit is only enabled when the actuator has been fed into the interlock and the latching bolt is in the blocking position. This is ensured by contact monitoring of the latching bolt.
