Miniature Photoelectric Sensor – WTB8-P2211

The WTB8-P2211 | W8 miniature photoelectric sensor offers high precision in a compact rectangular housing, making it an ideal solution for tight spaces and fine object detection. Utilizing background suppression technology, it ensures reliable detection of objects within 5 to 100 mm, regardless of background surfaces.

Equipped with a visible red LED light and an adjustable 4-turn potentiometer, it allows for precise sensitivity control. This sensor supports PNP output, light/dark switching, and operates with a rapid 1,000 Hz switching frequency, making it highly suitable for dynamic automation environments.

Designed for durability, the IP67-rated housing resists dust and water, while the supplied stainless steel mounting bracket makes installation easy and secure. Whether used in packaging, material handling, or assembly lines, the WTB8-P2211 delivers high performance in a small footprint.
