| Issue | Possible Cause | Recommended Action |
|---|---|---|
| No LED indication | No power supply | Verify 10–30 V DC is supplied correctly to the sensor (brown to V+, blue to GND) |
| Loose wiring or broken cable | Check cable continuity and ensure all wires are properly connected | |
| Internal fault | Replace sensor if wiring and power are correct | |
| LED ON but output not switching | Target object not within sensing range (Sn = 2 mm) | Ensure the target is within 1.6 mm operating range |
| Target material not suitable | Use standard Fe360 metal as target (correction factor = 1) | |
| False switching (intermittent signal) | Excessive vibration or unstable mounting | Secure the sensor properly using the M8 x 1 thread |
| Electrical noise/interference | Check for proper grounding; isolate sensor wires from high-power lines | |
| Sensor switches continuously | Metallic dust or object permanently in front | Clean sensing face and remove interfering objects |
| Short circuit in output line | Check load wiring, replace sensor if damaged | |
| Short sensor lifespan | Overload on switching output (>100 mA) | Ensure the output current does not exceed 100 mA |
| Incorrect power polarity | Use proper polarity (brown = V+, blue = GND) | |
| Cable damage | Excessive bending or mechanical strain | Use protective routing and strain relief for cable |
