Speed Switches

4B's line of speed switches includes: proximity, inductive, zero speed, stop motion and rotech 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 4B’s hazard monitoring systems to provide alarm and/or shutdown of your machinery when dangerous conditions are detected.
