The Electro-Sensors 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. In the event of rotational failure, such as broken drives, belt slippage, product overloads, clogs and jams, the SPDT 5-Amp control relay can be used to provide equipment shut down and/or alarm. This detection of a developing problem enables proactive maintenance to prevent equipment damage, product waste and excessive downtime.
