Verdrahtung, Commissioning and Troubleshooting Guide (SICK WT160-F410 / 6022788)

1. Verdrahtungsschritte
2. Brauner Draht (Stift 1) to DC10~30V+, blaues Kabel (Stift 2) to 0V. Verify voltage before power-up. AC supply and reverse polarity are forbidden.
3. Schwarzer Draht (Stift 3) for PNP output: Output voltage approximates supply voltage when target is detected. White wire (Stift 4) remains unconnected; do not short-circuit.
4. DIP-Schalter:

L/D: Licht an / Dark-on selection

Werkseinstellung: Licht an. Output activates when an object enters the sensing zone.

4. PLC wiring for PNP: Connect black wire to PLC input terminal; PLC common terminal to 0V.

Beschreibung der LED-Anzeige:

Grüne LED: Ständig EIN = Stromversorgung OK; Green OFF = No power or open circuit

Gelbe LED: Sensing indicator; Yellow ON = Target detected

Comissioning Guide (Focus on BGS Background Suppression)

2. Erfassungsbereich: 4–60 mm. Avoid mounting target closer than 4 mm (risk of false triggering). 8–50 mm is the preferred stable working zone.
3. BGS characteristic: Only detects objects within the set distance; Metallrahmen, 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.

3. Lichtfleck: Small red spot, suitable for tiny workpieces. For highly reflective bright metal parts, increase distance appropriately to avoid saturation and false triggering.
4. Installation: Keep optical window free of oil, dust and coolant. Prevent direct strong light exposure (Sonnenlicht, high-power light sources).
5. Fehlerbehebungstabelle

4. Einschränkungen & Notizen
5. Max output current: 100 mA. Do not drive solenoid valves or high-power relays directly; use intermediate relays.
6. IP67: Only protected against temporary splash water. Not for permanent immersion. Extra protection required for coolant or oil mist environments.
7. Auslaufmodell: 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.

1. Verpackung & Druckindustrie (BGS diffuse most widely used)

Flasche, pouch and carton presence detection, position confirmation and counting on conveyors

Kappe, 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

Vorteil: Conveyor and metal frame backgrounds do not trigger false signals. Ideal for compact stations such as WT160 series.

2. Elektronik, Halbleiter & 3C Assembly

Position confirmation of PCB boards, Steckverbinder und kleine Kunststoffteile

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)

3. Logistik, Lagerung & 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

4. Essen & Getränkeindustrie

Bottle and carton presence detection and counting on production lines

Bin / hopper level monitoring (voll / leer)

Workpiece position detection for aseptic packaging; stainless steel IP67 / IP69K hygienic versions recommended

Notiz: Ordinary diffuse sensors struggle with transparent bottles and films. BGS or laser types are preferred.

5. Automobilkomponenten, Werkzeugmaschinen & Benutzerdefinierte Automatisierung

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)

6. Büroausstattung & Leichtindustrie

Paper detection for printers and copiers

Automatiktüren, sensor taps, hand dryers and smart bins

Auxiliary anti-pinch detection for elevator doors

✅ Selection Guide for Drawing

1. Standard diffuse (without BGS) – Suitable for single, distant clean backgrounds. Niedrige Kosten. Strongly affected by target color and reflectivity; black targets may fail detection.
2. 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

Fernerkennung (>1 M; through-beam or retro-reflective preferred)

Highly transparent objects (transparente Folien, Glasflaschen; 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)
