SICK AG CM30-25NNP-KC1 Proximity Sensor

The SICK CM30-25NNP-KC1 is a compact, M30-capacitive proximity sensor designed to detect dielectric (non-metallic) materials across a 4 to 25 mm sensing range, wired as a 4‑wire device with NPN outputs offering both normally open and normally closed switching paths. It operates on a 10–36 VDC supply, enabling easy integration into standard industrial control circuits. The cylinder housing is molded plastic and rated IP67, suitable for wet or dusty environments, with a KC1 4‑pin connector configuration that supports reliable field installation in conveyors, hoppers, or packaging lines. With dual outputs, it provides flexible feedback for presence or level sensing of materials like plastics, powders, grains, or liquids without contact. Typical applications include detecting the presence or absence of non-conductive targets on automated equipment, level monitoring in simple reservoirs, and safety interlock-style signaling where fast, contactless sensing is beneficial. The CM30‑25NNP‑KC1’s combination of wide supply voltage range, rugged enclosure, and dual-output capability helps minimize wiring complexity while delivering precise, repeatable switching for process or machine control. Temperature tolerance and environmental sealing further support consistent performance in industrial settings, making it a suitable choice when you need a reliable capacitive sensor with versatile output options in a compact M30 form factor.
