TLS-GD2, Escape Release

This Escape Release option of TLS GD2 series is intended for machine guarding with full body access. The switch is installed so that the escape release push button on the rear side is accessible from inside the hazardous area. This allows the intentional unlocking of the TLS-GD2 from inside a hazardous area, providing a means of escape for a person who may become trapped.

High locking force
Five contacts: 2NC 1NO for door position monitoring, 1NC 1NO for lock monitoring


Actuator sold separately

Allen Bradley Guardmaster Guard Locking Switch

The Allen Bradley Guardmaster TLS-GD2 series positive mode, tongue operated guard locking interlock switch locks a machine guard closed until power is isolated and ensures that it remains isolated while the guard is open. This switch has three safety (NC) contacts and two auxiliary (NO) contacts. The head of this interlock switch has two entry slots and it can be rotated to provide four actuator entry points. It is provided with a blanking plug to seal the unused slot.

Actuator is not supplied and must be ordered separately and incorporates a power-to-unlock function

With the “power to lock” function, provisions are required to ensure that a dangerous situation cannot result from open circuit faults or power cuts.
