## Abstract

The Comprehensive Motion Detector Switch (CMDS) is a device used to sense repetitive mechanical motion in an industrial environment. The rotation of a pulley on a conveyor would be a typical application. This CMDS device is unique in that is has no internal moving parts, has a non-critical target sensing distance, and provides multiple output signals. The CMDS provides a speed-switch output which gives indication that the target device is in motion. The speed-switch signal is switch selectable between a pulsed output or as a constant stop-switch output. Additionally there is a field programmable under-speed signal available. This signal will indicate when the target device slows by a fixed percentage of the programmed speed. Another feature is that the CMDS device is available in both hard-wired and wireless versions.
