Risoluzione dei problemi comuni
- Sensor LED off: Check pins 12 power supply and polarity. Reverse polarity will not destroy the sensor but causes no output.
- Power supplied but no output when metal approaches: Verify target metal material; keep actual working distance ≤40 mm. Keep largesize metal objects away from sensor side faces. Although uprox+ resists predamping, adjacent bulk metal will still attenuate sensing performance.
- Output chattering: Do not exceed 200 mA load current; check powersupply ripple; reduce operating switching speed.

Selezione & Onsite Application Notes for CK40 NI50UCK40AP6X2H1141
- Nonflush mounting is mandatory, do not embed into metal. Safe practical operating distance ≤40 mm (0.81×Sn), avoid operating at full 50 mm nominal distance.
- Adjacent bulk metal causes predamping effect; keep sufficient metalfree clearance alongside sensor side faces.
- Weldspatterexposed environments: StandardCK40 housing does not resist weldspatter accumulation. Install protective baffles or select WeldGuardcoated variants.
- Wiring for M124pin male connector: Pin1 24V brown, Pin2 0V blue, Pin3 PNPoutput black, Pin4 unused.
