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

配線手順
Brown wire (ピン 1) to DC10~30V+, blue wire (ピン 2) to 0V. Verify voltage before power-up. AC supply and reverse polarity are forbidden.
Black wire (ピン 3) for PNP output: Output voltage approximates supply voltage when target is detected. White wire (ピン 4) remains unconnected; do not short-circuit.
ディップスイッチ:

L/D: Light-on / Dark-on selection

Factory default: Light-on. 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:

緑色のLED: Steady ON = Power OK; Green OFF = No power or open circuit

黄色のLED: Sensing indicator; Yellow ON = Target detected

Comissioning Guide (Focus on BGS Background Suppression)

検出範囲: 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; 金属フレーム, 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.
インストール: Keep optical window free of oil, dust and coolant. Prevent direct strong light exposure (sunlight, high-power light sources).
トラブルシューティング表

症状	Check Items
緑色の LED が消灯	供給電圧が不十分です, reversed brown/blue wiring, 壊れたケーブル, 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
黄色のLEDが点滅する, 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 ミリアンペア)

制限事項 & 注意事項
Max output current: 100 ミリアンペア. Do not drive solenoid valves or high-power relays directly; use intermediate relays.
IP67: Only protected against temporary splash water. Not for permanent immersion. Extra protection required for coolant or oil mist environments.
Discontinued model: 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.

包装 & 印刷業 (BGS diffuse most widely used)

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

キャップ, 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

アドバンテージ: Conveyor and metal frame backgrounds do not trigger false signals. Ideal for compact stations such as WT160 series.

✅ Selection Guide for Drawing

Standard diffuse (without BGS) – Suitable for single, distant clean backgrounds. 低コスト. 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

長距離検出 (>1 メートル; through-beam or retro-reflective preferred)

Highly transparent objects (transparent films, glass bottles; 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)
