Câblage, Commissioning and Troubleshooting Guide (SICK WT160-F410 / 6022788)
- Étapes de câblage
- Brown wire (Épingle 1) to DC10~30V+, blue wire (Épingle 2) to 0V. Verify voltage before power-up. AC supply and reverse polarity are forbidden.
- Black wire (Épingle 3) for PNP output: Output voltage approximates supply voltage when target is detected. White wire (Épingle 4) remains unconnected; do not short-circuit.
- Commutateur DIP:
L/D: Allumé / Dark-on selection
Valeur par défaut: Allumé. Output activates when an object enters the sensing zone.
- PLC wiring for PNP: Connect black wire to PLC input terminal; PLC common terminal to 0V.
LED Indicator Description:
LED verte: Steady ON = Power OK; Green OFF = No power or open circuit
LED jaune: Sensing indicator; Yellow ON = Target detected
Comissioning Guide (Focus on BGS Background Suppression)
- Sensing range: 4–60 mm. Avoid mounting target closer than 4 mm (risk of false triggering). 8–50 mm is the preferred stable working zone.
- BGS characteristic: Only detects objects within the set distance; cadres métalliques, conveyor belts and other rear backgrounds will not trigger the sensor.
✅ Commissioning verification method:
① Place target workpiece, yellow LED lights up;
② Remove workpiece, yellow LED turns off;
③ Keep workpiece in place and move background plate closer to the sensor. If yellow LED status stays unchanged, background suppression works properly.
- Light spot: Small red spot, suitable for tiny workpieces. For highly reflective bright metal parts, increase distance appropriately to avoid saturation and false triggering.
- Installation: Keep optical window free of oil, dust and coolant. Prevent direct strong light exposure (sunlight, high-power light sources).
- Tableau de dépannage
| Symptôme | Check Items |
| LED verte éteinte | Insufficient supply voltage, reversed brown/blue wiring, câble cassé, loose pins in M8 connector |
| Green LED ON, yellow LED always ON (no target present) | Background too close, highly reflective background, dirty lens, DIP switch set to Dark-on, internal optical failure |
| Green LED ON, yellow LED does not light with target present | Beyond maximum sensing range, dark high-absorption target, spot misaligned on workpiece, lens blocked |
| Yellow LED flickering, unstable signal | Excessive supply ripple, long cable with interference, loose mounting causing vibration, target at sensing boundary |
| Output intermittent while yellow LED works normally | Incorrect PLC wiring, shorted output load, PNP output overcurrent (max load current 100 mA) |
- Limites & Remarques
- Max output current: 100 mA. Do not drive solenoid valves or high-power relays directly; utiliser des relais intermédiaires.
- IP67: Only protected against temporary splash water. Not for permanent immersion. Extra protection required for coolant or oil mist environments.
- Modèle abandonné: Higher risk of optical drift and unstable signal with aging. Replace with WT160-F420 once instability occurs.
General Diffuse vs BGS Background Suppression Diffuse (WT160-F410 type)
BGS versions are preferred for cluttered backgrounds prone to false triggering.
- Conditionnement & Industrie de l'imprimerie (BGS diffuse most widely used)
Bottle, pouch and carton presence detection, position confirmation and counting on conveyors
Capuchon, label and sealing film presence check
Film feed deviation detection and missing material alarm
Workpiece trigger for printing stations and rejection of defective missing parts
Avantage: Conveyor and metal frame backgrounds do not trigger false signals. Ideal for compact stations such as WT160 series.
- Électronique, Semi-conducteur & 3C Assembly
Position confirmation of PCB boards, connecteurs et petites pièces en plastique
Gripper object detection for robotic handling
Material presence check for cells, modules and carriers
Workpiece trigger for labeling, screw locking and dispensing stations
Small terminal and component incoming detection (small red spot models)
- Logistique, Entreposage & Sorting Lines
Parcel passing detection, counting and diversion trigger
Bin / pallet presence detection at rack locations
Low obstacle detection for AGVs and positioning of material frames
Trigger assist for barcode scanning in parcel sorting
- Nourriture & Industrie des boissons
Bottle and carton presence detection and counting on production lines
Bin / hopper level monitoring (full / vide)
Workpiece position detection for aseptic packaging; stainless steel IP67 / IP69K hygienic versions recommended
Note: Ordinary diffuse sensors struggle with transparent bottles and films. BGS or laser types are preferred.
- Composants automobiles, Machines-outils & Automatisation personnalisée
Workpiece in-position and discharge detection for stamping and machining stations
Part placement verification on fixtures
Blockage and missing material alarm for material chutes
Auxiliary detection (not a replacement for safety light curtains)
- Matériel de bureau & Industrie légère
Paper detection for printers and copiers
Portes automatiques, sensor taps, hand dryers and smart bins
Auxiliary anti-pinch detection for elevator doors
✅ Selection Guide for Drawing
- Standard diffuse (without BGS) – Suitable for single, distant clean backgrounds. Faible coût. Strongly affected by target color and reflectivity; black targets may fail detection.
- BGS Background Suppression Diffuse (WT160-F410) – Triangulation principle. Only detects objects within the target distance and shields rear frames, conveyors and metal backgrounds. Suitable for short-range, cluttered background applications where workpieces sit close to conveyors; widely used in custom automation.
❌ Unsuitable Applications
Long-distance detection (>1 m; through-beam or retro-reflective preferred)
Highly transparent objects (transparent films, bouteilles en verre; unstable for standard diffuse sensors)
Mirror-like highly reflective workpieces (easy saturation and false trigger)
Direct strong sunlight, heavy dust or heavy coolant splash without shielding
Safety protection circuits (not safety-rated sensors)
