Description

Approach direction

Horizontal

Can be adjusted in 90° steps

Solenoid operating voltage and LED function display

  • 24 V AC/DC -15%, +10%

Guard locking type

TZ1

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

Switching element

SK

For monitoring the door/actuator position

ÜK

For monitoring the guard locking (built-in solenoid)

2121H

Slow-action switching contact 4 NC

Auxiliary release

This is used for releasing the guard locking with the aid of a tool. Sealing can be fitted to protect against tampering. Lead seal kit and tool included (already pre-assembled on versions with plug connectors).

Escape release

This is used for manual release of guard locking from the danger zone without tools.

3Safety switch and actuator must be placed together for mounting on the fixture/machines.
4The guard must not be used as a mechanical stop.
5Auxiliary release
6Escape release: There must not be any tensile force on the actuator when the escape release function is activated
aTravel without operation: actuator is in the guide slot, but function is not triggered.
bSwitching operation completed. Actuator must be inserted to this point to ensure safe switching. The actuator must be withdrawn at least to point a for switching off.
