Allen Bradley Guardmaster Hinge Switch, 600V AC / 24V DC Maximum Voltage, 85mm Shaft Length - 440H-R03079

Pick this hinge switch from Rockwell Automation's Allen Bradley Guardmaster range to prevent unauthorised access through restricted doorways. It's ideal for low-power systems due to its maximum DC voltage of 24V. The unit functions with two NC contacts securing the hinge and one NO contact that can be used to operate an alarm, adding a further safety benefit. Thanks to an adjustable cam you can adjust the degree of hinge actuation and determine the angle that isolates machine power.

• Tested to more than one million operations for longevity

• IP66 enclosure rating means that it's dust-tight and withstands spray from powerful water jets

• MTTFd exceeds 385 years for reliability

• Precise monitoring prevents access after sensing between 5° and 11° of door movement

• Works in a temperature range between -20°C and +80°C, so suitable for use in demanding environments

What material is this hinge switch made from?

This device has a heavy-duty die-cast alloy housing and a stainless steel shaft. Together, these deliver high impact resistance and resilience to mechanical stress.

Allen-Bradley Rotacam Hinge Switch

The Rotacam is heavy-duty, hinge-actuated safety-interlock switch. It can be used as, or connected to, the existing hinge pin for direct operation of the switch. 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…11°.

Can be used as a hinge pin on light and medium weight guard doors

Isolates power within 5° of door movement (2° to operate 2N/C safety contacts, 3° to operate 1N/O auxiliary - which can be used to indicate which guard has been opened, or can operate an alarm)

Degree of operation can be customized with adjustable cam

Robust die-cast case, ideal for heavy-duty applications

Contacts 2 NC & 1 NO

Forced guided contacts - complies with EN 1088, IEC 947-5-1
