Overview
The Euchner TP3-2131A024M is an electromechanical safety switch designed for machine guarding and access control. This safety switch features a separate actuator and plastic housing. It works with closed-circuit current principle, guard locking by spring force, and release by applying voltage to the guard locking solenoid. Order number 084142, this unit is rated for 24VAC/DC operation and includes monitoring contacts for door position verification.
