特徴とする近接スイッチ。A sensor section including a coil, an oscillation circuit whose oscillation state changes by changing the conductance of the coil depending on the presence or absence of an object near the sensor section, and an oscillation circuit that changes the oscillation state by changing the conductance of the coil depending on the presence or absence of an object near the sensor section. In a proximity switch comprising a circuit section including an output circuit for deriving a detection signal, and a cable connecting the sensor section and the circuit section, the sensor section is provided with a temperature that compensates for changes in conductance of the coil due to temperature. A proximity switch characterized by being provided with a compensator.
