Sensor element of an inductive proximity or distance sensor containing coil arrangement having electrically-conductive shielding with flange completely enclosing the coil arrangement and method for operating the sensor element

摘要

A sensor element of an inductive proximity sensor or distance sensor contains a coil arrangement with at least one excitation coil and at least one receiving coil and includes an electrically conductive shielding which contains a shielding cup that surrounds the coil arrangement laterally and on the rear face. A method operates the sensor element. The shielding of the sensor element further contains a flange which is provided on the front face of the sensor element, is connected to the shielding cup in an electrically conductive manner, and completely surrounds the coil arrangement.
