TP6-4120A024M (Order no. 084280)


Approach direction

Horizontal and vertical

Can be adjusted in 90° steps

Increased overtravel for horizontal approach direction

Solenoid operating voltage

  • AC/DC 24 V +10%, -15%

Guard locking type


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

Switching element


Slow-action switching contact 1 NC (door unlock request contact) + 1 NC + 1 NO (solenoid monitoring contact)

Auxiliary shutdown feature

When actuated, positively driven contacts 21-22 are opened. The guard remains locked. The auxiliary shutdown feature must be sealed to prevent tampering (for example with sealing lacquer).

Door unlock request contact

When the actuator is in the locked state, positively driven contact 21-22 is opened by pulling the guard (6 mm actuator stroke). This forwards a signal to the higher-level PLC. Depending on the control concept, the guard can be unlocked automatically when machine components that were still running have stopped.
