The Series PS Proximity Sensors are noninvasive sensors ideal for level detection, position indicating and counting applications. Capacitive type sensors detect electrically conducting and nonconducting materials, liquids, solids, or powders and include a sensitivity adjustment to differentiate between various materials. Inductive sensors detect ferrous or nonferrous metals only. A bright red LED indicates the state of the output switch. Sensors feature short circuit, reverse polarity and transient protection. Small size and threaded body make installation easy. Inductive sensors are embeddable (can be mounted flush). Capacitive sensors are environmentally protected to IP65 and Inductive sensors are protected to IP68. Units include two fixing nuts, screw driver, and operating instructions.

APPLICATIONS
Level control of liquids, powders, or solids, parts detection and counting, motion and speed detection, leak detection, rotation control.
