he SICK WTB2S-2P1310 (Part No. 1064393) is an ultra-compact background-suppression photoelectric proximity sensor crafted for detecting very small objects with exceptional speed and accuracy. Part of SICK’s renowned W2 series, this miniature sensor excels in scenarios where precision and spatial constraints are critical, such as miniature part detection, micro-positioning, and tight-machine integrations.

Despite its tiny dimensions (just 7.7 mm × 21.8 mm × 13.5 mm), the WTB2S-2P1310 delivers reliable detection within a close range of 3 mm to 15 mm, with a maximum capability of up to 18 mm—ideal for differentiating features or tiny components in close proximity. Its background-suppression design improves detection accuracy by ignoring unwanted reflections beyond its detection zone, ensuring precise operation in cluttered environments

At the heart of its optical performance is the PinPoint LED emitter. This 640 nm visible red LED generates a very small and sharply defined light spot—only around 2 mm in diameter when measured at just 8 mm from the sensor tip. This fine beam allows for exact alignment and detection of miniature targets, making setup and calibration quick and foolproof
