Multi-Voltage Underspeed Sensor

4B Components Ltd has developed a multi-voltage (24 -240 AC/DC) speed sensor to monitor rotating machinery for dangerous underspeed conditions. The M800 Elite speed switch is designed to detect belt slip, belt underspeed, stop motion, low speed, or zero speed on bucket elevators, conveyors, airlocks, mixers, fans, grinders, and many other rotating machines. Totally sealed and simple to calibrate, the M800 Elite works in the harshest of conditions. An inductive sensing device located in the nose of the M800 Elite enclosure will detect a metal target. This target can be an existing bolt head or the patented Whirligig fully guarded target and sensor mount. The Whirligig is available with 1, 2, 4, or 8 pulse targets, and attaches to the rotating shaft by either a ½-in. tapped bolt hole or magnetically using 4B’s Mag-Con adapter.
