摘要： A method of non-intrusive, inductive proximity sensing of a target through a conductive barrier comprises the steps of: disposing an inductive proximity sensor on one side of a barrier of conductive material; disposing a target on the other side of the barrier; determining an appropriate drive frequency for operating the proximity sensor based on the conductive material and thickness of the barrier; and operating the proximity sensor with the appropriate drive frequency to non-intrusively sense the proximity of the target through the conductive barrier. The method may include the steps of: varying the gap between the target and proximity sensor over a gap range; measuring the inductive output of the proximity sensor at the appropriate drive frequency and different gaps to obtain inductive output measurements at the different gaps; determining the operating induction bandwidth of the proximity sensor operated at approximately the appropriate drive frequency from the inductive output measurements at the different gaps; and using the determined induction bandwidth for proximity sensing of the target through the conductive barrier. The gap range may be based on a sensor/target gap variation during actuation for a particular application.

摘要： A proximity sensor assembly includes a multilayer printed wiring board proximity sensor, the proximity sensor being operable as either a variable-reluctance sensor or an eddy current loss sensor. The proximity sensor includes a plurality of layers configured to form at least one wound coil disposed about at least a portion of a core. The coils are electrically driven to generate an alternating magnetic field such that the inductance of the coils changes when a permeable or conductive object is moved in relation to the magnetic field. The change in inductance is recognized and used to detect the proximity and presence of an object relative to the sensor.
