TK1-4131AB024M (Sip. No. 099686)


Solenoid operating voltage

  • AC/DC 24 V +10%, -15%

Guard locking type


Closed-circuit current principle, guard locking by spring force. Release by applying voltage to the guard locking solenoid.

Switching element


Slow-action switching contact 2 NC + 2 NO

Auxiliary release

This is used for releasing the guard locking with the aid of a tool.

Contact separation

When actuated, positively driven contacts 21-22 and 41-42 are opened. Guard locking is not fully released. The contact separation must be sealed to prevent tampering (e.g. with sealing lacquer).
