The SICK WTB2S-2N3130 (Part No. 1064581) is a compact, high-performance photoelectric proximity sensor with background suppression, engineered for precise object detection in industrial automation environments. As part of the proven WTB2S sensor family, this model is optimized for applications that demand accurate sensing, robust construction, and reliable performance even under challenging operating conditions.

With its background suppression technology, the WTB2S-2N3130 ensures stable detection within a sensing range of 30 mm to 400 mm, ignoring interference from surfaces behind the target object. This feature makes it highly effective when detecting objects of varying colors, shapes, or reflectivity, as it focuses only on the intended target. The visible red LED emitter produces a clearly defined light spot, allowing operators to align and configure the sensor quickly and confidently, reducing installation time and ensuring proper operation.

The NPN light-switching output makes this model suitable for applications where NPN logic is required for system integration. It is capable of handling fast-moving production processes with a response time of less than 0.5 ms and a switching frequency of up to 1,000 Hz. This ensures that objects moving at high speeds on conveyors or automated equipment are detected reliably without delay or missed signals.

Built for durability, the WTB2S-2N3130 features a rugged housing made from ABS/PC with PMMA optics and is rated to IP67 protection standards. This robust construction provides resistance to dust, moisture, and industrial wear, ensuring consistent performance in harsh environments such as packaging lines, material handling systems, and robotic work cells. The sensor also maintains reliable operation in a temperature range from –25 °C to +55 °C, offering versatility across a wide range of industrial conditions.

Integration into existing automation systems is straightforward, thanks to its 10–30 V DC operating voltage and built-in electrical protection features, including reverse polarity protection, short-circuit protection, and overload protection. These safety functions not only safeguard the sensor itself but also protect the connected equipment, ensuring long-term system stability and reduced maintenance.

The WTB2S-2N3130 is particularly well-suited for applications in conveying, packaging, robotics, and automated assembly, where reliable detection at close to medium distances is critical. Its combination of compact size, fast response, and robust housing makes it a valuable solution for manufacturers seeking to optimize automation efficiency and reduce downtime.

In conclusion, the SICK WTB2S-2N3130 offers a powerful mix of precise detection, NPN output capability, rugged durability, and compact design, making it an excellent choice for industries requiring accurate and reliable sensing solutions in space-limited and high-speed environments.
