CR18-8DP Autonics Proximity Sensor
Autonics CR18-8DP Capacitive Proximity Sensor (M18, 8 mm, DC 3-Wire PNP)
Industrial M18 capacitive proximity sensor with 8 mm sensing distance for metal and non-metal detection.
Ideal for level detection of liquids, powders, plastics, glass, and packaging materials.
The Autonics CR18-8DP is a DC 3-wire capacitive proximity sensor designed to detect both metallic and non-metallic objects. With an 8 mm sensing distance and sensitivity adjustment, it is widely used for level detection in tanks and hoppers and for detecting powder, granules, plastic, glass, wood, and liquids in industrial automation environments.
