FIELD: machine building.
SUBSTANCE: proposed transducer comprises oscillator with inductive sensor composed if inductor arranged in annular groove of ferrite core open end, first threshold element, flip-flop with capacitative sensor, detector, second threshold element, logical element AND with its first and second inputs connected with appropriate outputs of threshold elements and its output making transducer output. Note here that capacitative sensor with central hole and inductive sensor are aligned to make transducer sensor. With metal part displacing relative to transducer sensor, signal with logical "1" is generated at transducer output to indicate control over said metal part. In case non-metal part is displaced, no said signal is generated and signal with logical "0" exists at transducer output.
EFFECT: higher reliability.
