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).
