General description
Typical application of our sensors
Our sensors contain a transistor oscillator which is actuated when a defined capacitance is exceeded
by the approach of the medium. The smaller the dielectric permittivity (Ɛr) the closer the medium has
to be approached. Our IAS sensors (inductive proximity switches / sensors) detect metallic media, our
KAS sensors (capacitive proximity switches / sensors) detect all media (including liquids). The effect can
also be achieved by detecting through non-metal materials, if the dielectric permittivity of the material to
be detected is higher (approx. factor 5 for KAS sensors). Depending on the version, the current change
of the oscillator is amplified into an analogue output signal or output as a binary signal via a switching
amplifier.
Mounting
Threaded sensors are supplied with 2 nuts. The following table should be consulted when considering
the maximum torque. For mounting in threaded blocks the maximum screw-in length has to be taken
into consideration (according to DIN 13). For sensors without thread the range of accessories provides
suitable mounting blocks.
