Inductive Proximity Switch

Inductive Proximity Switch
Inductive Proximity Switch
Product Code : LM4, LM5
Product Description

Product Description:

LM4/LM5 Inductance type proximity sensor
Inductive proximity switch 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,thirlpool will generate in metal object,resulting in attenuation of vibration 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 control for non-contact detection.

Main features:

  • compact volume
  • High precision of repeated location
  • Diversified exterior structures
  • Good performance of anti-interference
  • Many output forms
  • High on-off frequency
  • Wide voltage range
  • Dust proof,vibration proof,water proof and oil proof
  • with short-circuit protection and inverted connecting protection
  • Long service life
