Available. The Sick WTB9L-3P2261 is a compact photoelectric proximity sensor designed for precise detection of small objects in industrial automation applications. Featuring background suppression, it offers a sensing range from 25 mm to 300 mm, utilizing a visible red laser diode with a wavelength of 650 nm. The sensor operates with a supply voltage between 10 V DC and 30 V DC and provides a PNP complementary output. Its robust VISTAL® plastic housing ensures durability in harsh environments, and the device is rated IP66/IP67/IP69K for protection against dust and water ingress. The sensor is equipped with a 5-turn potentiometer for precise adjustment, allowing for fine-tuning of the detection range. With a response time of less than 500 µs and a switching frequency up to 1,000 Hz, the WTB9L-3P2261 is suitable for high-speed applications requiring reliable object detection.
