The Sick 1064249, model WTB2S-2N1310, is a compact and powerful photoelectric sensor designed for applications that demand precision in small spaces. As part of the W2 S-2 series, it combines advanced sensing technology with a miniature footprint, making it ideal for modern automation environments where space and accuracy are critical.

Measuring only 7.7 × 21.8 × 13.5 mm, the sensor’s ultra-small housing allows it to be mounted discreetly in tight or complex machine layouts. Despite its compact size, it provides background suppression starting at 20 mm, ensuring that only the intended target is detected, even when nearby surfaces or reflective backgrounds are present. This feature makes it particularly suitable for use in assembly lines, packaging machines, and small-part detection systems.

The sensing range of 1 mm to 18 mm, combined with a focused PinPoint red LED, delivers precise object recognition. The visible LED beam, with a narrow 2 mm spot size at 8 mm distance, enhances accuracy during setup and operation. This pinpoint beam allows the sensor to detect very small components or features that might be missed by broader light sources.

From an electrical standpoint, the WTB2S-2N1310 is engineered for speed and reliability. It provides an NPN light-switching output with a maximum load capacity of 50 mA. Its fast response time of less than 0.4 ms and high switching frequency of up to 1,200 Hz ensure consistent performance, even in high-speed production lines where rapid detection is essential.

Durability is another defining strength. The sensor features a rugged ABS/PC housing and PMMA optical components, built to withstand industrial environments. Rated IP67, it is resistant to dust and water ingress, ensuring reliable operation under challenging conditions. Furthermore, it supports a broad operating temperature range from –25 °C to +50 °C, making it suitable for use in a variety of climate and factory conditions.

In summary, the Sick WTB2S-2N1310 delivers advanced sensing performance in an exceptionally small package. With its combination of miniature size, pinpoint LED technology, background suppression, fast switching, and robust construction, it is perfectly suited for demanding automation tasks. Whether used in electronics assembly, material handling, or precision packaging, this sensor ensures accuracy, efficiency, and long-term reliability.
