Inductive Proximity Sensor Non-flush Type Two Wires AC Voltage Proximity Switch LM18-2008A

LM series inductive proximity sensors is composed of three parts: oscillator, switch circuit and magnified output circuit. The oscillator will generate an alternating electric field. When the metal object approaches this electric field and reaches the induction distance, whirlpool will generate in metal object, resulting in attenuation of vibrate on and then stop. The change of vibration and stop of oscillator is treated by behind stage magnified circuit and converted to switching sign, triggering driving con-contact detection.
