Key Features & Strengths:

Long Sensing Range: Retro-reflective sensors offer a longer range than diffuse sensors. The WL11-B560 has an impressive sensing range of up to 8 meters (approx. 26 feet), making it suitable for applications where the sender and receiver need to be housed in the same unit but distance is a factor.

Polarization Filter (Key Feature): This model is equipped with a polarization filter. This is a critical feature that allows the sensor to reliably detect shiny, reflective objects (like metal packaging, polished surfaces, or glass). Without this filter, such objects might falsely appear as the reflector, preventing detection. The filter ensures the sensor only recognizes the light returned from its specific, corner-cube reflector.

High Excess Gain: Provides a strong light signal, ensuring stable operation even in dirty environments or with partially obscured reflectors.

High Immunity to Ambient Light: Uses modulated infrared light (880 nm), which allows it to effectively filter out interference from ambient light sources like sunlight or factory lighting.

Robust Metal Housing: Housed in a heavy-duty, nickel-plated brass body. This construction provides excellent resistance to mechanical impact, chemicals, oils, and vibrations, making it ideal for harsh industrial environments.

High Protection Rating: Features an IP67 protection rating, meaning it is completely protected against dust and can withstand temporary immersion in water.

Clear Status Indicators: Integrated LEDs provide clear visual feedback for power (green) and output switching (yellow), simplifying setup and diagnostics.

Fixed-Cable Connection: The model designation suggests a fixed cable connection (e.g., 2m PVC cable), offering a secure and reliable wiring solution.
