Hinge Switches

A heavy-duty hinge actuated safety interlock switch, the Rotacam shaft can be used as, or connected to, the existing hinge pin for direct operation of the Hinge Switches. Machine power is isolated when the guard has been opened just 5°. For applications requiring a larger degree of operation the internal cam can be adjusted from 5° to 11°.

The Rotacam is available with two N.C. safety contacts and one N.O. auxiliary contact. The Hinge Switches includes the necessary safety related functions, such as forced guided contacts and a tamper resistant mechanism, allowing machinery to be safeguarded in compliance with the machinery directive.

The die-cast housing of Hinge Switches is sealed to IP66 and features one M20 conduit entry (1/2in NPT and connector style also available). Two different shaft lengths of 30mm and 85mm can also be specified. EX and Pneumatic styles of Rotacam are also available; see the Explosion Proof section on page 16-1 for more information.
