Inductive Proximity Sensor Lj12A3-4-Z/Bx Detection Switch NPN DC6-36V 4mm Normally Open Proximity Switch

This Inductive Proximity Switch is widely used in automatic control industry for detecting, controlling, and noncontact switching. When proximity switch is close to some target object, it will send out control signal.

Also can be used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial etc.

These are a popular choice for 3D Printers, being ideal for bed leveling.

 

Inductive proximity sensor is a great way to precisely detect when a metal object is at a given distance. Since this is a non-contact sensor, it is ideally suited to situations where dust, dirt, or liquids may be present. This specific sensor triggers when the sensor tip is 4mm away and features an LED that also illuminates when the sensor is tripped. Mounting this sensor is quite easy – it has a long threaded body allowing for a considerable adjustment.

Internally this sensor is wired like an NPN transistor; the base pin of the transistor is triggered when the metal object is at a distance of 4mm. The sensor operates at 6 – 36VDC and will output the same voltage on the output wire. Because of the higher voltage, the output will need to have the logic level shifted to a lower voltage to operate with a Raspberry Pi or Arduino. To wire up this sensor: Brown = DC in: (6 – 36VDC) , Blue = Ground , Black = Output Signal .

  • MODEL:  LJ12A3-4-Z/BX
  • OUTPUT:  NPN, 3 WIRE, NO (NORMAL OPEN)
  • WORK VOLTAGE: 6VDC – 36VDC
  • OUTPUT CURRENT: 300mA. (SINK)
  • SIZE: DIA. 12 mm. L: 64 mm. (BODY)
  • CABLE LENGTH: 100 cm.
  • DETECTION RANGE: 4 mm.
  • DETECTION OF METAL: (COPPER, IRON, ALUMINUIM ETC.)

This Inductive Proximity Switch is widely used in automatic control industry for detecting, controlling, and noncontact switching. When proximity switch is close to some target object, it will send out control signal.

    The machine came a few days earlier than stated. Very well packaged and the installation also went smoothly. After I executed the commands and calibrated the device, everything went as it should and the machine correctly found the position of the laser head. I hope that it will remain stable in the future and that the values will remain as it is calibrated. Everything works correctly I am really impressed with the performance of the machine and the results of the laser work.

    I did find that there was some smell while using it and found it would be better to use this engraver in a ventilated area. I think it should be necessary to buy another air assist to direct the airflow to the outside, the effect will be better!

    I am a beginner and this laser engraver is equipped with everything I need. I USED GBRL SOFTWARE WITH A MAC SYSTEM AND THE CONNECTION WAS EASY. When cutting wooden blocks, I find it as easy as carving planks. And the effect is not bad, it is a good laser machine.
