4B's line of speed switch sensors includes proximity, inductive, zero speed, stop motion, and protect encoders to monitor dangerous belt slip, underspeed, or stop conditions on conveyors, bucket elevators, and any other shaft driven machinery. Our non-contacting sensors can be used to detect screw conveyor flights, elevator bucket bolts, and other moving ferrous targets. Speed switches can be connected to a PLC or to one of 4Bs hazard monitory systems to provide alarm and/or shutdown of your machinery when dangerous conditions are detected.
