  • It is a component widely used in the automatic control industry for detecting, controlling, and noncontact switching. When the proximity switch is close to some target object, it will send out a control signal.
  • As it is a capacitive type proximity switch, its detecting object target is not limited to an only conductor, but also liquid and even powder things, like plastic, water, glass, oil, etc.
  • It's widely used in machines, paper making, the light industry for limiting stations, orientation taking count, speeding trials, etc.
  • Integrated circuit proximity switch which is composed of oscillator and shaping amplifier oscillator start-up after induction head switches the last alternating magnetic field.
  • This series of proximity switches for high-frequency oscillation with no contact, no pressure, no spark, quickly issued a detection signal.
  • This series of proximity switches are widely used in modern industry, machinery, metallurgy, transportation, electric power, military, textile, chemical, mining, scientific research departments of machine tools, and industrial automatic production lines.
