Following two principles are used in a inductive sensor. Now that we’ve understood what proximity sensors are, we’ll dive further into the various types; each well suited to its specific applications and environments. To help determining whether an inductive camshaft sensor is functioning correctly, different possible deviations from the example signal are mentioned along with probable causes. There are many types of inductive sensors, and common ones are self-inductive, mutual inductance and eddy current three. In addition, they are insensitive to vibration, dust and moisture. When the coil is connected to the measuring circuit and the excitation power is turned on, a voltage or current output proportional to the displacement input amount can be obtained. Three types of photoelectric sensors are available. Inductive proximity sensor with gold-plated pins. Ready?
