SIEMENS sensor-detector AGG5.310

SIEMENS sensor-detector AGG5.310 AGG5.310 is an inductive sensor. Suitable for LMV5, usually used with signal disc (outer diameter 70mm). It works using the principle of electromagnetic induction and contains components such as coils, oscillators and other components. The shell has dust-proof and waterproof functions, and its induction distance is determined by the coil diameter and is related to the size and material of the metal object to be tested. The main function is to detect the approaching situation of an object, generate high-frequency signals through the oscillator, and cause the coil to emit an alternating electromagnetic field. When a metal object enters the electromagnetic field, it is excited to generate eddy currents, which in turn causes the oscillator to attenuate. The threshold switch controls the shutdown of the output stage based on the specified attenuation value to determine whether there are metal objects approaching. It can be used to detect the position, speed and status of the objects, etc., and is widely used in industrial fields such as machinery, chemical industry, and metallurgy.
