Auxiliary release on the switch head
Actuating element for contact separation on the front
Cable entry M20 x 1.5

Description

Solenoid operating voltage

AC/DC 24 V +10%, -15%

Guard locking type

TK1	Closed-circuit current principle, guard locking by spring force. Release by applying voltage to the guard locking solenoid.

Switching element

528	Slow-action switching contact 1 NC + 1 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 are opened. Guard locking is not fully unlocked. The auxiliary release must be sealed to prevent tampering (e.g. with sealing lacquer).
