Capacitive Sensors

BCF Type

In difficult applications conventional sensors don't offer sufficient detection reliability. Particularly with conductive coatings, detection problems can occur that may cause total failures. This source of errors can now be excluded thanks to the new switching technology of the BCF sensors combined with electrode and compensation optimisation. The potentiometer with which the switching distance is set on conventional capacitive sensors is located in the sensitive generator area. This has the disadvantage that the sensor is very sensitive to RF interference and other interference sources.  These TURCK capacitive sensors are designed with the potentiometer located in a less sensitive area of the circuit. Additional protective measures are required for environments in which extreme interference is present. The BCF  series offers the following solution: All sensors of this series are fully resistant to radiated and conducted RF interference, burst interference, and electrostatic discharge (ESD).
