GN139.1 Hinge Zinc Die Cast, Plastic Coated with Safety Switch
These hinges with integrated safety switches, GN 139.1, have been designed for the position monitoring of doors and covers of machines and plant.
Opening the door will activate the switch contacts which, in turn, will then e.g. 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 (see contact travel diagram).
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.
