Effective for detecting transparent objects. The beam passes through the (transparent) target twice, so light attenuation increases. Since the light axis of both the receiver and emitter are a coaxial structure, high-accuracy positioning is possible. Model: Transparent-object Detection Sensor DR-Q Series The Z3D-W20 wide angle diffuse reflective. This document explains how photoelectric sensors detect transparent objects, introducing different sensor types and the optical principles used to identify transparent materials, along with factors that affect detection accuracy. A photoelectric sensor is a small electronic device and a key.

High detection capabilities for stable detection of a wide range of transparent workpieces in the food and packaging industries, including glass bottles, PET bottles, films, and trays. This fiber optic sensor is built for transparent detect scenarios—ideal for industries like packaging (clear film checks), electronics (transparent component inspection), and food (see-through container verification).
