49C Series Diffuse Reflection Sensor with Background Suppression

49C Series Diffuse Reflection Sensor with Background Suppression

Product Introduction

The 49C Series is a high-performance diffuse reflection sensor utilizing background suppression technology to ensure precise object detection across varying surfaces. Engineered for reliability, it minimizes black-white detection errors to <10% within a 1200 mm range, making it ideal for industrial automation tasks. With a wide operating range (0.005–3 m for white surfaces, 0.02–2 m for gray, and 0.05–1.5 m for black), the sensor adapts to diverse materials. Powered by a red LED light source (630 nm wavelength), it features dual relay outputs, transient protection, and a rugged IP67-rated housing, ensuring consistent performance in harsh environments from -40°C to 60°C.
