Abstract: A method for communication, intended in particular for the purpose of a configuration, calibration, parameterization, interrogation or even a test or diagnosis, between a master device and a slave product including at least a processing unit and a direct current power supply line or input, and, if necessary, at least one output line and/or output interface. The method includes transmitting to the product data that can be interpreted by the processing unit thereof, the data being transmitted via the power supply line and by modulating the supply voltage.

Abstract: An electronic device, in particular of the sensor or detector type, includes a housing having first and second longitudinal opposite and sealed ends. The housing contains an electronic card and with its inside volume being filled by an insulating filler material that coats the card, its components, and the end of a connecting cable connected to the card, the housing including an opening at its second end, which is sealed by a connected piece that is equipped with a passage opening for the connecting cable. The sealing piece includes at least a second through opening for injecting filler material (5), this or each second opening being sealed by a plug (9) made of a material that conducts and diffuses light, of which a portion is positioned in the vicinity of, and even in contact with, at least one light signaling element (10) or light indicator carried by the card (4).

Abstract: A sensor or detector device includes a box in the form of a tubular hollow body, through whose opening a connecting cable passes and that is sealed by a connected plug. The device also includes a card or an analogous substrate, carrying the electronic components of the sensor or detector and mounted in the box, by being coated by an insulating filler material filling approximately the entire remaining inside volume of the latter. The Device (1) is characterized in that it includes a mechanical element for the positioning with wedging of the card (6) in the box, preferably along a median plane or with longitudinal symmetry (PM) of the latter, with at least a portion of the element being integrated in the plug (5).
