About this product
An inductive proximity sensor with a 4 mm sensing distance that detects conductive metal objects without contact. It uses a 3-wire connection (brown, blue, black) and a cable of about 1.2 m. It is used for end-stop detection, position sensing and counting metal parts in automation, 3D printer and CNC projects.

Frequently asked questions
What is the price of LJ12A3-4-Z/BX Inductive Proximity Sensor, 4mm, 3-Wire in Egypt?
LJ12A3-4-Z/BX Inductive Proximity Sensor, 4mm, 3-Wire currently costs 133 EGP in Egypt.
Where can I buy LJ12A3-4-Z/BX Inductive Proximity Sensor, 4mm, 3-Wire in Egypt?
LJ12A3-4-Z/BX Inductive Proximity Sensor, 4mm, 3-Wire is available from Most Electronics. Compare the offers above to find the best price.
How do I wire the 3-wire sensor?
Connect brown to the positive supply, blue to 0 V (GND), and black to the signal input. With NPN output, the black wire pulls to GND when metal is detected, so use a pull-up resistor or INPUT_PULLUP on the microcontroller pin. Check the label for the exact output type.
Can I power it from the Arduino 5 V pin?
The listing gives two supply ranges (5–30 V and 6–36 V), so 5 V is not guaranteed. A 12 V or 24 V supply is the safer choice, with the signal level adapted to your microcontroller's logic voltage.
