GN139.1, Hinge Zinc Die Cast, with Safety Switch and Cable Connector

These hinges with integrated safety switches have been designed for monitoring doors and covers of machines and plant equipment. Opening the door will activate the switch contacts which, in turn, will then interrupt a protective circuit via break contact (NC) and at the same time signal the door opening by closing a normally open contact element (NO).

The contact blocks are fitted with positive opening slow action contacts, i.e. they will definitely be separated when activated and have no hysteresis. The angle at which the switching points are reached are adjustable.

Together with the integrated contact blocks, the hinges are a compact, easy to mount unit with an attractive design. The mounting from the back makes the hinge more tamper proof.


Zinc die casting, plastic coated, silver metallic

Pin - Stainless Steel NI AISI 303

RoHS compliant
