Description

Guard locking principle

Operating current (power to lock): In the case of a safety guard with guard locking according to the open-circuit current principle, the safety guard is locked until the power supply to the guard locking solenoid is break-before-make. The guard is unlocked by spring force. This is also referred to as electrical guard locking.

Switching element

4131

Slow-action switching contact

Contacts for guard locking: 2 positively driven, positively driven contacts 2 NO contacts

Auxiliary release with triangular wedge

The auxiliary release on the switch head allows access to the machine in the event of a malfunction, e.g. a power failure. It is unlocked using a tool or a key. The auxiliary release must be secured against misuse (sealing, laking).

Contact separation

When actuated, the contacts are opened. The guard locking is not completely released. To prevent tampering, the contact separation must be sealed (e.g. with sealing lacquer).

Without prevention of inadvertent locking position (faulty closure protection)

The TK safety switch does not have a prevention of inadvertent locking position (faulty closure protection). This must be implemented separately.
