Safety Switch Hinges Monitor Covers of Equipment

Sept. 14, 2017
J.W. Winco offers easy monitoring of machine equipment with their safety hinges.

316L Stainless Steel GN 139.5 Hinges with Safety Switch are designed for use in monitoring doors and covers of machines and equipment. Opening the door activates the switch contacts, which 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, as they will definitely be separated when activated and have no hysteresis. The angle at which the switching points are reached is 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 makes the hinge particularly tamper-proof.


Hinges with operating angle greater than 0-deg. and hinges with other contact load ratings are available upon request. The hinge body and hinge pin are made from 316L stainless steel, with the body having a polished finish.
