Product Feature

Long distance photoelectric sensor

Reflector-Free Design, One Sensor for Multiple Uses Breaks free from the constraint of reflectors in industrial applications—no need to distinguish between diffuse reflection, reflector-type, or through-beam sensors, significantly simplifying product selection.

Intelligent Background Suppression for Accurate Detection
Automatically filters out interference objects, reducing false trigger rates by 90%! Precisely identifies transparent glass, reflective metals, dark-colored objects, and other targets without errors.

Selectable Detection Distances & Stable Performance
Optional detection distances: 1m/2m/3m, with full-range coverage from 0.05M to 50M for flexible application. High positioning accuracy, compact size, and focused light beam (no diffusion). Can stably detect transparent objects without being affected by the target’s color or material.
