Sick CM18 Series Capacitive Barrel-Style Capacitive sensor, M18 x 1, 3 → 8 mm Detection, NPN Output, 10 →

The CM capacitive proximity sensors detect objects and levels regardless of color, reflectance, and gloss of the surfaces. In the process, they detect powdery, granulated, liquid, and solid materials – even through non-metallic walls made of plastic or glass.

The proven and rugged sensors are cost effective and feature high electromagnetic compatibility (EMC), which prevents switching errors and reduces downtime. The variants with a PTFE housing are ideal for detecting the levels of chemical compounds, e.g. acids or solvents.
