The invention relates to a shielded double-coil multilayer assembly intended to be used in an inductive detector. This multilayer assembly comprises a plurality of stacked parallel separated layers, namely:

Shielded double-coil multilayer assembly for inductive detector

The invention relates to an inductive proximity detector comprising an oscillating circuit excited with resonance by a generator and comprising a detection coil sensitive to a metal target to be detected, wherein the oscillating circuit comprises a reference coil arranged to present a mutual inductance with respect to the metal target to be detected that is substantially lower than that of the detection coil with respect to the metal target, the oscillating circuit comprises a switch able to assume two positions to connect each coil alternately, the detector comprises processing means connected to the coils making it possible to determine the presence or absence of the metal target close to the detector.

Inductive proximity detector with switched windings

A detector for monitoring rotation of a target includes a sensor unit, a microcontroller, and an operator conversation apparatus. The operator conversation apparatus is connected to the microcontroller and enables setting of the detector in a working mode or a learning mode.

Detector for monitoring rotation

A self-adaptable proximity detector delivering a binary output signal for the presence or absence of a target. The proximity detector includes a processing unit and operates according to a short learning mode for an adjustment relative to its environment, according to a long learning mode for an adjustment relative to its environment and to a target, and according to a working mode corresponding to normal operation. The proximity detector also includes a variable digital storage resistor driven by the processing unit in the learning mode and connected to the detection stage so that variation of the value of the digital resistor causes a variation of the switching threshold. In the working mode, the processing unit is in a standby state and the variable digital storage resistor remains at its set operating value.

Learning proximity detector

A component of a generally cylindrical luminous signaling column housing plural conductors that are substantially parallel to the axis of the cylinder and a printed circuit bearing plural LED luminous sources. The printed circuit is oriented such that its main plane is parallel to the axis of the component and bears plural LEDs on each surface. The cylindrical luminous signaling column includes a cylindrical inner surface provided with light-diffusing reliefs.
