High and Low Range Types for 6 to 3000 RPM Operation
25 Turn Potentiometer and LED Indicator Simplifies Precise Ser‑Point Adjustment
Accurate and Repeatable to 5% of Nominal Speed
The Motion Detector Series detects under‑speed conditions in conveyor lines, machine tools, ventilating systems, or any other rotating shaft where a minimum speed requirement exists. Typically, a flat, keyway, or bolthead, is detected, precisely timed, and compared during each revolution to a set‑point adjustment made at minimum speed. Any drop in speed immediately produces an output which may be used for emergency stop or other control function. The Motion Detectors operate as AC or DC switches and are available with high‑ and low‑speed range.
