摘要： A safety switch (1) having a reading head (2) and an actuator (3) having a transponder (4) and being movable relative to the reading head (2). Encoded signals of the transponder (4) are detectable by means of the reading head (2). As a means for detecting encoded signals, the reading head (2) has a resonant circuit (6) controlled by a processor unit, with the distance between the actuator (3) and reading head (2) being determined by means of an amplitude evaluation of the signals of the transponder (4) detected with the resonant circuit (6). Control signals are generated as a function of the distance signals thus determined.

摘要： A non-contact proximity switch with an oscillation circuit (L 1, C 1) which is activated in a step-like manner, has a reference voltage source (6) which produces at least one reference voltage level (U.sub.ref) and has at least one comparator (5) which compares the amplitude of the transient response with the associated reference voltage level (U.sub.ref) in order to be able to detect at least one value that is distinctive for the time curve of the decaying oscillation from at least one transient response of the oscillation circuit (L 1, C 1) after such an activation. At least one counter (7, 10) counts, at least within a portion of the decay period of the transient response, the number (DA) of the half-waves of the transient response, the peak of which deviated from the associated reference voltage level (U.sub.ref) in one of the two directions.

摘要： A target device for use with a switch device of a proximity switch has a wireless receiver means (6) for detecting and receiving a first pulsating signal (A) with a first carrier frequency (f1) from a nearby transmitter module (5), demodulating (6, 7) the received signal, and if a superimposed digital signal is present, inverting (9, 10, C4, and Q1) the superimposed received digital signal or, if the superimposed digital signal is absent, passing the existing energy through (10). The target device also has a wireless transmitter means (12) for modulating and sending the inverted pulse train if this exists by the second carrier frequency (f2) to the receiver switch unit (13). Additionally, the target comprises functionality to transmit the carrier frequency (f2) continuous and unmodulated where a continuous and unmodulated carrier frequency (f1) is present. However, upon existence of the pulsating signal only one of the receiver (6) and the transmitter (12) receives or transmits a signal at a given time.

摘要： A method and apparatus for sensing the proximity of a target object includes a sensor inductor (L.sub.S, 38) connected in series with an identical reference inductor (L.sub.R, 36) between an input and ground to form an inductive divider network. The sensor inductor is positioned so that its inductance can be varied in response to the proximity of a target object (14, 40) while the inductance of the reference inductor remains constant. Voltage pulses are periodically applied to the divider network from a source (32, 34) and divide across the reference and sensor in accordance with the ratio of the inductances, as varied or not by the presence of the target object. A detector (30) monitors the output of the divider network and provides a target status signal indicative of the proximity of the target object. For low-power operation, the detector circuit and conductive divider network are periodically and momentarily energized in synchronism. This enables configuration of a self-contained, leadless proximity sensor having a battery power source and an optical output.
