摘要： A proximity detector is provided with an oscillating circuit generating cyclically an unsustained pseudo-oscillation. The detector includes a processing circuit having a comparator which compares the relaxation voltage of the oscillating circuit with a predetermined threshold and a logic circuit which generates control pulses with low duty ratio for a switch in series with the oscillating circuit and also an output signal as a function of the measurement pulses delivered by the comparator. The closure duration of the switch is substantially equal to half the pseudo-oscillation period.

The oscillating circuit has a first terminal connected to an energy source by a first switch and a second terminal referenced alternately to a potential substantially equal to half the high potential of the power supply and to the low potential of the power supply. This alternate reference is determined by a second switch controlled synchronously with the first switch by the logic circuit.
