Built with Sickβs trusted optical sensing technology, the WTB4S-3P2261 Photoelectric Sensor delivers consistent performance with background suppression, making it ideal for detecting small or reflective objects in cluttered industrial environments. It operates on a 10β30 V DC supply and features a PinPoint LED light source emitting a visible red beam at 650 nm. The light spot measures Γ 6.5 mm at 150 mm, offering high visibility and accuracy for setup and alignment. The sensor's sensing range spans from 10 mm to 180 mm, providing flexibility in detecting objects of varying sizes and distances.
The WTB4S-3P2261 uses a PNP digital output with light/dark switching, supporting rapid response times under 0.5 ms and a switching frequency of 1,000 Hz. Its 5-turn potentiometer allows for fine adjustment of sensing distance, ensuring optimal setup in complex automation tasks. The device is housed in a slim, rectangular ABS body (dimensions: 12.2 mm Γ 41.8 mm Γ 17.3 mm) with a PMMA front screen, and it includes a durable M8, 4-pin male connector for secure integration. Rated to IP66/IP67, it withstands harsh industrial environments including dust, moisture, and fluctuating temperatures from β40 Β°C to +60 Β°C.
With its extended sensing range, reliable suppression of background noise, and rugged IP-rated housing, the Sick WTB4S-3P2261 is trusted by engineers across sectors such as packaging, electronics, and machine automation. Itβs designed for seamless integration, low power consumption (20 mA), and long operational life.
