9.  Troubleshooting Guide 

IssuePossible CauseRecommended Action
No LED indicationNo power supplyVerify 10–30 V DC is supplied correctly to the sensor (brown to V+, blue to GND)
Loose wiring or broken cableCheck cable continuity and ensure all wires are properly connected
Internal faultReplace sensor if wiring and power are correct
LED ON but output not switchingTarget object not within sensing range (Sn = 2 mm)Ensure the target is within 1.6 mm operating range
Target material not suitableUse standard Fe360 metal as target (correction factor = 1)
False switching (intermittent signal)Excessive vibration or unstable mountingSecure the sensor properly using the M8 x 1 thread
Electrical noise/interferenceCheck for proper grounding; isolate sensor wires from high-power lines
Sensor switches continuouslyMetallic dust or object permanently in frontClean sensing face and remove interfering objects
Short circuit in output lineCheck load wiring, replace sensor if damaged
Short sensor lifespanOverload on switching output (>100 mA)Ensure the output current does not exceed 100 mA
Incorrect power polarityUse proper polarity (brown = V+, blue = GND)
Cable damageExcessive bending or mechanical strainUse protective routing and strain relief for cable
