The SICK WTB2S-2E1310 (Part No. 1064397) is a highly compact photoelectric sensor belonging to the W2 miniature series. Designed for modern automation systems, it offers superior background suppression in a small footprint, making it particularly valuable in tight installations and applications where space efficiency is a priority. Despite its compact housing size of only 7.7 mm × 21.8 mm × 13.5 mm, it delivers reliable detection of objects with outstanding accuracy.

This model is distinguished by its extended sensing range. It operates reliably from 3 mm up to 50 mm, with a maximum reach of up to 80 mm under optimal conditions. This capability makes it versatile across applications such as packaging lines, assembly processes, robotics, and electronics production, where both short-range and mid-range detection are required.

The integrated PinPoint LED emitter is a defining feature of the WTB2S-2E1310. Operating at a wavelength of 640 nm, the visible red beam produces a sharply defined light spot of approximately 2 mm. This makes sensor alignment quick and straightforward, while ensuring precise detection even on glossy or low-contrast surfaces. The visible spot also reduces setup time and simplifies maintenance during operation.

Performance speed is another strong advantage. The sensor features a PNP light-switching output, responding in less than 0.5 ms and handling switching frequencies up to 1,000 Hz. This ensures it performs reliably in high-speed conveyor systems, pick-and-place machines, and other automated environments where accurate, fast object detection is critical.

Reliability is reinforced by the IP67-rated enclosure, protecting the sensor against dust and water ingress. Constructed from durable ABS/PC housing materials with PMMA optics, the WTB2S-2E1310 is engineered to withstand mechanical stress and environmental challenges commonly found in industrial operations. It functions seamlessly across temperatures from –25 °C to +50 °C, with storage capability down to –40 °C and up to +75 °C.

The unit is simple to integrate, operating on a standard 10–30 V DC supply with a low current draw of approximately 20 mA. It connects via a 3-wire, 2 m PVC cable, ensuring flexibility during installation. Built-in electrical protections against short-circuit, reverse polarity, and overload further enhance safety and longevity in daily operation.

In summary, the WTB2S-2E1310 offers a balance of extended detection range, fast response, compact size, and rugged durability. It is ideally suited for industries that require precise, space-saving sensors capable of handling high-speed and demanding applications, such as electronics assembly, packaging, robotics, and medical device production.
