GN 139.1 Hinges

J.W. Winco Inc. offers series GN 139.1 hinges with electrical switching function, with safety switch, in metric sizes. These RoHS-compliant hinges have been designed for use on monitoring doors and covers of machines and equipment. Opening the door activates the switch contacts. This causes an interruption in a protective circuit via broken contact (NC) and at the same time signals 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 is 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 particularly tamper-proof.

Hinge body is zinc die-cast, with silver metallic powder coated finish. Hinge pin is stainless steel. Offered in types with connector plug on top, bottom, or on back with 200mm cable. All types are available with narrow hinge wing or broad hinge wing. The mounting from the back makes the hinge particularly tamper-proof.
