Allgemeine Fehlerbehebung

1. Sensor LED off: Check pins 12 power supply and polarity. Reverse polarity will not destroy the sensor but causes no output.
2. 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.
3. Output chattering: Do not exceed 200 mA load current; check powersupply ripple; reduce operating switching speed.

Application Cases for TURCK uprox+ CK40Series Square Sensors (NI50UCK40AP6X2H1141)

Kernvorteile: Factor1 uniform metal sensing, 5direction adjustable sensing face, 50 mm long sensing distance, weldingfield magneticfield resistance, IP68, 30~+85 ℃ wide temperature range, M12 quickdisconnect connector. 40×40 square housing, optimized for longrange detection, high installation tolerance, mixedmetaltarget detection and heavyEMIinterference environments.

1. Automotive Weldingshop / BIW Production Lines (Typical Highfrequency Working Condition)

Scenario 1: Skidconveyor Position Detection

Zweck: 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

Zweck: Position feedback for robot grippers and locatingpins (retracted / extended status), to prevent collision caused by incomplete fixture positioning.

Notiz: For heavyweldspatter stations, select variants with WeldGuard antispatter coating. Install protective baffles for standard PBThousing sensors.

2. Logistiklager, Stacker Cranes & AGVs

Scenario 1: Stackercrane Fork Limit & Strokeend Detection

Zweck: Zeropoint and upper/lowerlimit detection for fork extension / retraction; forkinposition signal for anticollision protection against racking.

Arbeitsbedingungen: Lowtemperature warehouse down to 20 ℃; heavy vibration & Schock; mixed steelaluminumalloy target profiles.

CK40 Benefits: Operating down to 30 ℃; 30 g shock resistance; 50 mm long sensing distance maintains stable signal despite fork mechanical oscillation; M12 quickconnector simplifies field replacement & Wartung.

Scenario 2: AGV Liftingmechanism Limit & Palletpresence Detection

Zweck: Upperlimit & lowerlimit detection for AGV lifting platforms; palletpresence confirmation on conveyor lines.

Pain Points: Mixed steelpallet / aluminumpallet handling, conventional sensors lose range on aluminum targets; heavy vehiclebody vibration for AGVs.

Auswahlhinweis: NI50UCK40AP6X2H1141 (PNPNO), directly compatible with PLC digital input modules.

Auswahl & Onsite Application Notes for CK40 NI50UCK40AP6X2H1141

1. 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.
2. Adjacent bulk metal causes predamping effect; keep sufficient metalfree clearance alongside sensor side faces.
3. Weldspatterexposed environments: StandardCK40 housing does not resist weldspatter accumulation. Install protective baffles or select WeldGuardcoated variants.
4. Wiring for M124pin male connector: Pin1 24V brown, Pin2 0V blue, Pin3 PNPoutput black, Pin4 unused.
