Description
The SICK WTB12 / WL12 series are compact, high-performance photoelectric sensors designed for precise object detection in industrial automation. These sensors utilize either red light (WTB12) or laser (WL12) technology with background suppression (BGS) or retroreflective (3N) principles, ensuring reliable operation regardless of surface color or reflectivity. Featuring M12 connectors, IP67 protection, and robust metal or plastic housings, they are ideal for harsh environments in packaging, material handling, and assembly lines.
