Product Introduction
Our CZ-460 Limited Reflective Photo Sensor is a limited reflective photoelectric sensor adopting linear light spot design, specially engineered for substrate industry applications. It features a 5mm×30mm linear light spot to stably detect workpieces with hollowed structures or concave-convex surfaces, while optimized optical design reduces color difference interference for consistent detection in multi-color workpiece production lines.
Key Benefits
▶Linear light spot design: It adopts a 5mm × 30mm linear light spot, which is not easily disturbed by substrate notches and hollow structures, enabling stable detection of workpieces with concave-convex surfaces.
▶Excellent color difference suppression: Optimized optical lens greatly weakens the detection deviation caused by different workpiece colors, realizing reliable sensing on mixed-color production lines.
▶Tool-free sensitivity setting: No sensitivity adjustment is required before operation. Side mounting holes with M3 screws simplify assembly and cut commissioning time significantly.
