Description

The SICK WL11G-2B2531 is a specialized retro-reflective photoelectric sensor engineered specifically for the reliable detection of transparent objects such as glass bottles, PET containers, and clear films. Unlike standard sensors that often look right through clear materials, this device utilizes advanced ClearSense technology to detect the slightest attenuation of light intensity, ensuring stable operation even with highly transparent targets. It features Autocollimation optics that combine the sender and receiver into a single optical axis, effectively eliminating blind spots and allowing for detection right up to the sensor face. With a precise PinPoint LED for easy alignment and a rugged IP67 housing, it is the industry standard for high-speed packaging and bottling applications.

    SICK WL11G Research Summary

    SICK WL11G-2B2531

    Clear Material Detection Sensor

    The sensor that sees the invisible. Using high-sensitivity attenuation logic to detect glass, PET bottles, and transparent films that standard sensors miss.

    1. Detection Logic

    Glass bottles reduce light intensity by only ~15%. Standard sensors interpret this as "clear path." The WL11G interprets this as "object present."

    Standard Sensor

    Status: NO DETECTION

    Signal Drop: 15%
    Threshold: 50% (Missed)

    SICK WL11G

    Status: OBJECT DETECTED

    Signal Drop: 15%
    Threshold: 10% (Triggered)

    Sensitivity Analysis

    The difference lies in the Switching Threshold. The WL11G monitors the continuous signal level. When a clear object passes, the signal dips slightly.

    • 1 100% Signal: Clear path to reflector.
    • 2 85% Signal: Glass bottle in beam.
    • 3 Result: WL11G triggers at ~90% threshold.

    Autocollimation Optics

    In many sensors, the sender lens and receiver lens are separate. This creates a "blind spot" close to the sensor where objects cannot be detected.

    The WL11G uses a single lens for both sending and receiving.

    This creates a precise, coaxial beam with zero blind zone, allowing reliable detection of bottles even if they pass immediately in front of the sensor face.
