Item # SRC Speed Responsive Switch, Compact Motion Control

The Model CMS Motion Sensing Control is a compact 
unit designed to include all mechanical and electronic 
components in one housing. It will produce an output 
signal at a predetermined speed which may be either 
underspeed or overspeed. Rugged, heavy duty 
construction combined with solid state electronics and 
photo-electric technology, make this one of the most 
advanced detectors available.
The Model CMS protects all valuable rotating equipment 
including belt conveyors, bucket elevators, rotary 
feeders, or screw conveyors. It operates in either a 
clockwise or counterclockwise direction and mounts in 
any position.
The control can be mounted in any position, but the 
mounting surface should be flat and smooth. The 
bearing brackets and shim plates shown in the chart can 
be used to mount the unit directly to the pillow block 
supporting a shaft. Normally, only 1/4” mounting bolts 
and lock washers are required. If vibration is extreme two 
of the mounting holes should be doweled and bolts used 
in the others.
The shaft of the device should be mounted in line with 
or parallel to the driving shaft. Model CMS can be 
driven by a flexible coupling, V-belt drive, chain drive, or 
gear drive.
