The CMB 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, for example. The proven and rugged sensors are cost efficient and feature extremely high electromagnetic compatibility (EMC), which prevents switching errors and reduces downtime. Thanks to the IO-Link interface, different parameterizations can be performed and detailed data read out. This makes the CMB devices suitable for more complex applications and enables predictive maintenance.
