The STP4A-2131A024L024M provides monitored guard locking for industrial machine safety applications. The switching element incorporates two positively driven contacts and one NO contact for guard-lock monitoring, together with one NC contact for door-position monitoring.

The unit also features an auxiliary mechanical release and two LED indicators.

Included with this unit is the metal safety-switch actuator shown in the photos. This is the mechanical component that enters the switch head when a machine guard or safety door is closed. The actuator itself carries the marking 120295; its exact Euchner order number has not been independently confirmed.

An approximately 1.8 m yellow connection cable is fitted. The remote end of the cable is open and terminates in individual conductors, as pictured.

Used, fully functional.
