Hinges with integrated safety switch GN 139.1 are 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 include 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.
The compact construction combines safety and attractive design. The hinges are tamper-proof because of the covered mounting from the backside.
