The SICK WTB2S-2P3110 (Part No. 1064395) is a miniature photoelectric proximity sensor designed for high-precision object detection in environments where both space and reliability are critical. Part of the proven W2 sensor family, it combines advanced background suppression with a compact housing, measuring only 7.7 mm × 21.8 mm × 13.5 mm, making it ideal for tight machine spaces and applications with limited installation room.

At its core, the sensor operates with background suppression technology, which ensures it detects the intended target without interference from reflective or complex backgrounds. The effective sensing range spans from 3 mm up to 15 mm, and under ideal conditions, the range can extend to 18 mm. This versatility allows the sensor to perform well with a wide variety of objects, including those with challenging surfaces such as shiny metal or dark plastics.

The inclusion of PinPoint LED technology sets the WTB2S-2P3110 apart. Emitting at 640 nm, the LED produces a sharp, visible light spot approximately 2 mm in size at an 8 mm distance. This small, concentrated beam makes alignment fast and straightforward, while enhancing detection accuracy even for low-contrast objects.

Speed is another defining strength. With PNP light-switching output, the sensor achieves a lightning-fast response time under 0.4 ms and supports switching frequencies up to 1,200 Hz. This makes it exceptionally suitable for high-speed conveyor belts, rapid pick-and-place robotics, and other fast-moving industrial processes where detection delays cannot be tolerated.

Durability is ensured by its IP67-rated enclosure, which protects against dust and water ingress. The housing is constructed from strong ABS/PC materials with PMMA optics, guaranteeing long service life under demanding conditions. The sensor operates reliably in a temperature range from –25 °C to +50 °C, with storage capacity extending from –40 °C up to +75 °C.

Installation and integration are straightforward thanks to its 3-pin M8 connector with 200 mm PVC cable, providing compatibility with standard industrial wiring setups. Power requirements are modest, running on 10–30 V DC with a typical current consumption of only 20 mA. Built-in safeguards such as short-circuit, reverse polarity, and overcurrent protection add an extra layer of reliability and system safety.

In summary, the WTB2S-2P3110 combines compact construction, fast response, and rugged reliability to deliver premium object detection performance in miniature form. It is especially effective in industries like electronics assembly, medical technology, packaging, and robotics, where high precision and small sensor size are indispensable.
