TK

Safety switch TK... with guard locking and guard lock monitoring (without protection against unintentional closing)

Wherever the application of conventional type 2 safety switches is no longer possible, the TK is like a duck in water. With a locking force of more than 5,000 N, it is set up for very high loads. The TK has guard lock monitoring and is equipped with safety switching contacts.

The principle of operation is simple: If a safety system is to be locked, the guard locking pin prevents it from opening. The guard locking pin is only retracted after the guard locking solenoid is supplied with power. The safety system can then be opened. The pin position can be monitored via the safety switching elements.

Features

Mechanical Release

Is used for releasing the guard locking with the aid of a tool. To protect against tampering, the mechanical release is sealed with sealing lacquer.

Auxiliary shutdown feature

When actuated, positively driven NC contacts 21-22 or 41-42 are opened. The safety guard remains locked. The auxiliary shutdown feature must be sealed to prevent tampering (for example with sealing lacquer).
