Product Description

New Genuine German SICK WL11G-2B2531 Compact W11G-2 Series Polarized Retroreflective Photoelectric Sensor

 

This authentic SICK WL11G-2B2531 belongs to premium W11G-2 miniature rectangular photoelectric sensor series, equipped built-in polarisation coaxial optical filter, specially optimized for stable detection of transparent plastic film, glossy aluminum cans, polished metal and reflective packaging surfaces, eliminate false triggering caused by surface stray reflection. Effective adjustable sensing distance covers 0m to maximum 4m, fitted high-brightness 640nm visible red pinpoint LED light spot for fast on-site optical axis alignment without auxiliary calibration tools. Adopts universal dual NPN/PNP complementary switching output, freely switchable light-on / dark-on logic via wiring control, fully compatible with all mainstream European PLC sink/source input control cabinets. Operating supply voltage 10-30 VDC with integrated reverse polarity, short-circuit, overcurrent and EMC multi-layer anti-interference protection circuit, effectively prevent sensor burnout from field wiring misoperation. Robust ABS plastic rectangular housing reaches triple protection grade IP66/IP67/IP69K, withstand 80ºC high-pressure hot water jet cleaning, food workshop detergent chemical splash, ink mist and metal dust accumulation, perfectly match strict sanitation food & beverage production line washdown requirements. Ultra-fast ≤330μs response time and 1500Hz ultra-high switching frequency adapt high-speed continuous packaging, film slitting and logistics conveying material counting scenes. Standard M12×1 5-pin waterproof male electrical connector, wide operating temperature range -30ºC ~ +60ºC to suit cold frozen food storage lines and high-temperature printing & injection molding workshops. Original factory sealed packaging includes dimension drawing, M12 wiring schematic, full English official datasheet and PL80A reflector matching installation guide, convenient European food & packaging automation integrator transparent material detection circuit design and bulk spare parts inventory stocking.

FAQ 4

Question: What is the core advantage of built-in coaxial polarisation filter compared with ordinary non-polarized retroreflective sensors?
Answer: Ordinary mirror reflection sensors will generate continuous false trigger signals when detecting transparent film, shiny metal cans and polished plastic surfaces due to direct surface light reflection; WL11G-2B2531 integrated coaxial polarisation optical filter blocks all stray surface reflection light, only receives directional reflected beam from dedicated PL80A reflector, realize stable, error-free detection for high-gloss and fully transparent objects without signal drift or missing counts.
 

FAQ 5

Question: What is the difference between WL11G-2B2531 and WSE11G-2B2531 sensor models?
Answer: Optical detection principle distinguishes the two variants:
WL11G-2B2531: Coaxial polarized retroreflective type, max 4m range, dedicated transparent & glossy packaging material detection (this listing model)
WSE11G-2B2531: Split through-beam emitter-receiver separate type, max 10m ultra-long distance for thick transparent bottle barrier detection

 

Both share dual NPN/PNP output, IP69K washdown protection and M12 5pin connector, only differ in optical detection structure and maximum sensing range.

FAQ 6

Question: Can WL11G-2B2531 sensor work stably after daily high-pressure hot water cleaning in food beverage filling workshop?

 

Answer: Yes. This model reaches top IP69K food sanitation washdown protection standard, passed ECOLAB detergent corrosion test, resist 80ºC high-pressure hot water jet and food cleaning chemical splash, fully suitable for daily regular cleaning food & beverage automated production lines.
