Capacitive Sensor

CM30-25NAP-KW1 is a capacitive proximity sensor from SICK, designed for non-contact detection of objects such as solids and liquids. It features a robust M30 x 1.5 threaded plastic (PBT) housing with a 4–25 mm adjustable sensing range (non-flush mounting). The sensor operates on 20–250 V AC, provides NC or NO output via a 2-wire, 2-meter cable, and allows sensitivity adjustment with a potentiometer. 

It offers a switching frequency of 10 Hz, high EMC resistance, IP67 protection, and reliable operation in harsh industrial environments from -25°C to +80°C.
