Capacitive Sensor

CM30-25NNP-KW1 is a capacitive proximity sensor from SICK, designed for non-contact detection of various materials including solids and liquids. It features a robust M30 x 1.5 threaded plastic (PBT) housing, with an adjustable sensing range from 4 to 25 mm (non-flush mounting). 

The sensor operates on 10–36 V DC, provides an NPN complementary output (NO + NC), and connects via a 4-pin M12 male connector. It offers a switching frequency of 50 Hz, sensitivity adjustment via potentiometer, and is rated IP67 for dust and water protection, making it suitable for harsh industrial environments.
