The SICK WTB8-P2131 is a miniature photoelectric proximity sensor from the W8 series, utilizing background suppression technology for reliable object detection in close-range industrial automation applications. It features a visible red LED light source operating at 650 nm wavelength with an adjustable sensing range from 40 mm to 300 mm via a 4-turn potentiometer. The sensor provides PNP switching output with selectable light/dark switching modes through a rotary switch. Housed in a compact rectangular ABS plastic enclosure measuring 11 x 31 x 20 mm and weighing just 10 g, it is designed for panel mounting with M3 threaded holes. The device includes IP67 enclosure protection, making it suitable for harsh industrial environments. It connects via an M8 3-pin connector and is supplied with a stainless steel mounting bracket (BEF-W100-A).
