Hinge Safety Interlock Switches With Voltage Free Outputs

IDEM’s HS Hinge Switches are available in either die cast or stainless steel housing with a mirror polished finished and has been designed to be mounted for interlock position sensing of hinged moving guards.

The HS-range have been designed to be fitted to the hinged axis of machine guard doors and provide a robust hinge function in addition to interlock position sensing. They feature positive opening contacts in accordance with IEC 60947-5-1 and after fitting the switch offers a very high degree of anti-tamper.

The HSM is used to mount the machine guard door into the machine guard frame and contact blocks are available in slow make/break 3NC 1NO, or 2NC 2NO. Enclosures are protected to IP67 or IP69K with a low profile, hygienic design for washdown.

Operation of the switches is achieved by the rotating action of a cam and actuator to cause deflection of the switch plunger.

Positive actuation of the contacts is achieved at only 6 degrees of opening of the guard and can be adjusted up to 12 degrees if required upon installation.
