4B M100 Stopswitch – Inductive Zero-Speed / Stop-Motion Sensor
The M100 Stopswitch is a simple, self-contained inductive shaft-speed monitor with a single set point that signals when the shaft has stopped rotating. It's ideal for process control, motion detection, and stopped-shaft indication.
An inductive sensor in the nose of the enclosure detects a metal target — an existing bolt head or a device attached to the shaft. The M100 requires no calibration and provides an output the moment the shaft stops turning.
