GN 139.1 hinges with safety switch are used for hinged and opening protective equipment such as doors or covers on machines, in plants, in automation engineering and in the automobile industry. The hinge is compact and sturdy, making it the ideal choice for many applications.
Classed as protective equipment, GN 139.1 hinges with safety switch can prevent hazardous situations as the contacts change their status from a defined opening angle forward. This switching point can be adjusted within the range +4°.
The electrical switching elements are fully integrated in the mechanical hinge and are invisible from the outside, allowing the hinges to be classed under IP 67 (plug-type version) and IP 69K (cable version). Two contact switches offer double safety! The concealed bolt attachment from the back also makes this hinge particularly tamper-proof.
The GN 139.2 hinges are similar in design and differ externally only by featuring a connector plug, making them the ideal choice as add-on hinge with unchanged perfect appearance.
Flat and angled mounting plates are available to mount the hinges, allowing them to be mounted from the front or in the clearance between door frame and door.
Oblong holes are designed for mounting to profile systems.
In general, the GN 139.1 hinges with safety switch conform to many international standards and directives.
