SICK WL250-2R1531 6 044 700 Photoelectric Sensor

The SICK WL250-2R1531 (part no. 6044700) is a compact retro-reflective photoelectric sensor from SICK's WL250 family. It employs a dual‑lens, light-on switching arrangement with a visible red LED and is designed for reliable long-range detection when paired with standard reflectors PL80A or P250. The rectangular housing measures 20 x 60 x 43.9 mm and is made of ABS plastic with an IP67 rating for protection against dust and water. It provides a relay output over a 5‑wire cable (2 m) and operates at 10–30 V DC; the device includes a 2‑turn potentiometer for adjustment and a polarization filter for ambient light rejection. Sensing range is 0.01 m to 15 m (up to 12 m with certain reflectors, per the reflector used), with a light spot of about Ø260 mm at 8 m and a focus of roughly 2 degrees. The WL250-2R1531 is designed for light-on switching and includes BEF-W250 and P250 accessories in the package; service life is about 100,000 hours at +25 °C. Common applications include object detection on production lines, product flow control on conveyors, presence detection in packaging equipment, motion sensing for automatic doors, and guidance tasks in logistics and warehouse automation.
