Perfect For
- 3D Printer Auto Bed Leveling & Homing: Use as an endstop or Z-probe for precise metal bed detection on printers like Ender 3, Prusa, and custom CoreXY builds.
- CNC Machine Home & Limit Switches: Replace mechanical limit switches with this wear-free sensor for reliable axis homing on CNC routers, mills, and laser cutters.
- Industrial Conveyor Object Counting: Detect and count metal parts on production lines with the fast 500Hz response for accurate throughput monitoring.
- Robotic Arm Position Feedback: Integrate into robotic joints or end-effectors for non-contact position confirmation and collision avoidance.
- RPM & Speed Measurement: Mount near a rotating shaft with a metal target to measure motor RPM for tachometer or closed-loop speed control projects.
- Automated Door & Gate Systems: Detect vehicle or metal gate positions for automatic opening/closing systems in parking and access control.
- Arduino & Raspberry Pi
LJ18A3-8-ZBX 8mm Inductive Proximity Approach Sensor

Wiring Guide
| Wire Color | Connection |
| Brown | V+ (6-36V DC positive supply) |
| Blue | V (DC ground / GND) |
| Black (Signal) | NPN NO output - connects to PLC input, microcontroller digital pin (with pull-up resistor), or relay module |
Note: NPN output sinks current to ground when activated. For Arduino use, connect the signal wire to a digital input pin with a 10kOhm pull-up resistor to 5V. The pin reads LOW when metal is detected and HIGH when no metal is present.
