GN 139.5 Hinges with Integrated Safety Switches 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 (see diagram under "Contact termination." 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.
Hinges with operating angle > 0° and hinges with other contact load ratings available upon request.
