SICK NT6-03022 Through-Beam Photoelectric Sensor

The SICK NT6-03022 Through-Beam Photoelectric Sensor is a contrast-sensing solution in the NT6 family, featuring separate emitter and receiver heads and a vertical light spot for reliable contrast detection. It supports a sensing range of up to 5 meters (0–5 m) and offers a PNP transistor output with selectable dark-on or light-on operation, enabling straightforward integration with common PLC inputs. With a fast 2 ms response time, it is suitable for high-speed conveyor and packaging applications where precise edge or mark detection is required. The through-beam arrangement minimizes sensitivity to target reflectivity, making it robust against varying backgrounds and ambient light. Adjustable switching frequency lets you tailor performance to the pace of your process, while the compact, torsion-free mounting of the emitter and receiver simplifies installation on production lines. Ideal for color/contrast marking checks, registration sensing on conveyors, and other tasks that rely on reliable contrast detection across a defined gap, the NT6-03022 delivers quick, decisive sensing without reliance on surface reflectivity.
