The M100T is a compact, self-contained shaft rotation monitoring speed switches ideal for detecting unwanted slow down or stoppage of process equipment. The unit has a terminal block inside the housing for easy wiring connection, calibration, and installation, and a relay setpoint range of between 5 rpm and 100 rpm.

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 down time.
