ABSTRACT:
The invention relates to a temperature-stable inductive proximity switch having a transistorized resonant circuit oscillator. The feeding into the emitter-to-collector circuit of the resonant circuit transistor T1 of a balancing current, which depends on the individually determined temperature of the resonant circuit transistor T1 and the individually determined temperature of the resonant circuit coil, ensures that the proximity switch is temperature-stable with respect to its switching distance for every adjusted basic current.
