LJ12A3-4-Z/BX NPN DC5-36V 4mm Normally Open Tube Type Inductive Proximity Sensor Switch

This LJ12A3-4-Z-BX-NPN DC 5-36V Inductive 4mm NPN-NO Proximity Sensor Switch also known as Approach Sensor is a component widely used in the automatic control industry for detecting, controlling, and non-contact switching. When the proximity switch is close to some target object, it will send out a control signal.

When the metal approaches near-proximity switch sensing area, an Edy Current is induced in metal. Which in turn disturbs the magnetic field produced by the Inductive Proximity Sensor. This change is sensed by the sensor.

These inductive proximity switches can be non-contact, have no pressure, no spark, and quickly issue the electrical command. Accurately reflect the position and stroke movement mechanism. Positioning accuracy, operating frequency, service life. Easy to install and suitable for harsh environments.

This 4mm proximity sensor can detect a variety of metals, miniature size, long life, low price, shielded type installation, anti-interference ability, 1mm detection distance, used for precise positioning of molds, precision machine tools, and robots. 

Applications:

  • It is widely used in machines, paper making, light industry for limiting stations, orientation taking count, speeding trials, etc.
  • Used in the automatic control industry for detecting, controlling, and noncontact switching.
