Hinges GN 139.1 with integrated safety switches have been designed for monitoring doors and covers of machines and plants. 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 make the hinge more tamper-proof.

Cable with connection coupling

8-pole, 5 or 10 meters long:

  • Cables with conntector coupling GN 330 -M12x1-8-G-5.
  • Cables with conntector coupling GN 330 -M12x1-8-G-10.

  • Hinges with operation angle > 0°
  • Hinges with other contact terminations
