Title
(EN) Sensor element of inductive proximity or distance sensor, and method for operating the sensor element
(ZH) 感应式接近度传感器或距离传感器的传感器元件和用于操作所述传感器元件的方法
Abstract
(EN)
The invention relates to a sensor element (10) of an inductive proximity sensor or distance sensor (12), the element containing a coil arrangement (26) with at least one excitation coil (T, C) and at least one receiving coil (R+, R-) and comprising an electrically conductive shielding which contains a shielding cup (24) that surrounds the coil arrangement (26) laterally and on the rear face. The invention also relates to a method for operating the sensor element (10). The sensor element (10) is characterized in that the shielding further contains a flange (22) which is provided on the front face of the sensor element (10), is connected to the shielding cup (24) in an electrically conductive manner, and completely surrounds the coil arrangement (26).
