Dépannage courant
- 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.

- Automotive Weldingshop / BIW Production Lines (Typical Highfrequency Working Condition)
Scenario 1: Skidconveyor Position Detection
But: Position confirmation of transport skids, to inform PLC for skid release / locking. Skids are made of mixed carbon steel, aluminum alloy and stainlesssteel materials.
Pain Points: Conventional proximity sensors suffer heavy sensingdistance attenuation for aluminum targets; strong magneticfield interference in welding stations causes false triggering; variable onsite installation space requires multidirection detection capability.
CK40 Advantages: Constant 50 mm sensing distance for iron / aluminium / stainlesssteel via Factor1; weldingmagneticfield immunity; 5way rotatable sensing face without mechanicalbracket modification; long sensing distance absorbs assembly tolerances.
Installation: Mounted on side / bottom of machine frame, nonflush mounting; safe working distance controlled ≤40 mm.
Scenario 2: Toolingfixture & locatingpin Position Feedback
But: Position feedback for robot grippers and locatingpins (retracted / extended status), to prevent collision caused by incomplete fixture positioning.
Note: For heavyweldspatter stations, select variants with WeldGuard antispatter coating. Install protective baffles for standard PBThousing sensors.
- Entreposage Logistique, Stacker Cranes & AGV
Scenario 1: Stackercrane Fork Limit & Strokeend Detection
But: Zeropoint and upper/lowerlimit detection for fork extension / retraction; forkinposition signal for anticollision protection against racking.

Sélection & 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.

- Critical Application Limitations
- Flush metalembedding installation is prohibited. Do not operate at full 50 mm nominal distance; keep practical working distance ≤40 mm.
- For weldspatterexposed locations, standard housing cannot resist weldspatter accumulation. Install protective baffles or select WeldGuardcoated variants.
- Never exceed 200 mA loadcurrent; otherwise cyclic shortcircuit protection will trigger and cause output chattering.
