Allen Bradley GuardMaster Non-Contact Switch

The Allen Bradley GuardMaster 440N series magnetic safety switch has a supply voltage rating of 250VAC, 300VDC at 0.5A current. This switch comes with S21 housings and a 3m cable. It incorporates several magnetically sensitive elements, which must be triggered in a particular sequence to operate correctly. It is designed to operate with its actuator, helps to prevent defeat ability by a simple magnet. Its moulded-in brackets and diminutive size make it extremely versatile and simple to install. This switch has a sensor that must be connected to the Sipha control unit, giving a monitored circuit. For high-risk applications, the control unit is used with a single sensor to give a high-integrity system. It has facilities for connecting a manual reset button and monitoring external devices such as contactors.
