About this item

  • Item Name: Inductive proximity switch; Model : LJ12A3-4-Z/BY; Output type : NPN NO(Normal Open); Wire type : DC 3 wire type (black, brown, blue).
  • Detecting: Detecting distance : 4mm. Detect object : metal. The working principle of an inductive sensor: It senses the change of the electromagnetic field emitted from its tip. When the magnetic field approaches a metal object, the amplitude of the magnetic field changes. This change is sensed by the internal circuit.
  • Voltage: DC 6-36V; Current output : 300mA. If you want the probe to work under DC 5V, DC 6-36V NPN sensors can also work under DC 5V.
  • Application: Diameter of column sensor: 12mm. The induction proximity switch has fast response speed and high sensitivity, which is very suitable for 3D printers.
  • Package Content: 2 pcs NPN NO 4mm inductive proximity switch; 2 pcs I-type bracket; 2 pcs L-type bracket.

NPN - Forget sinking sourcing, you have plus, minus and third wire that switches to 0V, common or negative, however you like to refer. Sense distance as advertised.
