Hinges GN 139.5 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.

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. Hinges GN 139.6 without switching function act as additional hinges, e.g. for larger doors or gates where several hinges are required.

Cable with connector coupling

8-pole, 5 or 10 meter long:

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

  • Hinges with operating angle > 0°
  • Hinges with other contact loadings
