The Euchner TP3-4141K024M is a guard locking safety switch with slow-action switching contacts, used for door monitoring and interlocking on machine guards. It provides two door position and two guard lock monitoring positively driven contacts, with locking based on the closed-circuit current principle and a solenoid operating voltage of AC/DC 24 V. The housing is IP67 rated and constructed from reinforced thermoplastic, with silver alloy, gold-flashed contacts, suitable for installation in any orientation. Connection is made via 3 x M20 x 1.5 entries, and the switch is designed for applications with an approach speed of up to 20 m/min.
