Inductive proximity switches LSI |
| |
The inductive proximity switch operates on the
principle of the attenuated LC oscillator: when metal enters the
response range of the proximity switch, power is withdrawn from the
system. The metal part causes an energy loss, which is caused by the
formation of eddy currents. The eddy current losses are related to the
size and nature of the metal part.
The change in the oscillation amplitude of the oscillator results in a
current change, which is evaluated in the downstream electronics and is
converted into a defined switching signal. A steady-state signal is
available at the output of the unit, for the duration of the
attenuation.
