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.
