M100T and M5000T speed switches are complete rotation monitoring systems, ideal for detecting unwanted slowdown or stoppage of process equipment. These switches have a terminal block inside the housing for easy wiring connection and installation. The M100T has a relay setpoint range of between 5RPM and 100RPM. The M5000T has a relay setpoint range of between 100RPM and 5000RPM. This range is where the relay can be set to trip - both switches have the same operating range. These switches are commonly used to monitor drive trains, power driven components, crushers, exhaust fans, screw conveyors, or tail pulleys on belt conveyors and elevator legs.
