The SICK WTB2S-2P1145 (part number 1064614) is a miniature photoelectric proximity sensor that provides high-precision detection in tight installation environments. Its rectangular housing measures just 7.7 mm wide, 21.8 mm high, and 13.5 mm deep, making it perfectly suited for compact machinery, robotics, and applications where available mounting space is extremely limited.

At the core of this sensor’s design is its PinPoint red LED technology, which generates a highly visible, sharply focused light spot. This ensures accurate and effortless alignment, reducing installation time and increasing reliability in operation. The visibility of the LED also supports easier diagnostics and adjustment in the field, helping operators confirm sensor performance at a glance.

The WTB2S-2P1145 is engineered for short-range detection with background suppression, making it ideal for applications where objects must be detected at close distances with precision. Its working range spans from 5 mm to 40 mm, and it can extend up to 45 mm when detecting reflective surfaces. This ensures stable and consistent detection performance in applications such as part positioning, presence verification, and small component monitoring.

Speed and reliability are central to the sensor’s operation. With a response time of less than 0.5 milliseconds and a switching frequency up to 1 kHz, it is well-suited for high-speed production environments. The PNP light-switching output, capable of handling up to 50 mA, ensures compatibility with standard control systems, providing dependable signal transmission even in fast-moving automation processes.

The sensor operates on a 10–30 V DC supply, with low power consumption of around 20 mA. It is designed with built-in protection against reverse polarity, short circuits, and overload conditions. These safety features extend the product’s service life and minimize risks of damage to connected devices.

Mechanically, the IP67-rated enclosure ensures the WTB2S-2P1145 is dust-tight and resistant to water ingress. The rugged housing is constructed from durable ABS/PC plastic with PMMA optical components, making it suitable for use in harsh industrial environments. Whether exposed to dust, splashing water, or mechanical stress, the sensor continues to deliver consistent performance.

For connectivity, the WTB2S-2P1145 comes with a 2-meter, 3-wire PVC cable. The cable’s slim 3 mm diameter and 0.09 mm² conductor cross-section allow easy routing and integration into tight installation spaces.

In conclusion, the SICK WTB2S-2P1145 combines compact design, reliable close-range detection, fast response, and rugged protection in a single miniature sensor. It is the ideal solution for OEMs, system integrators, and machine builders seeking a space-saving yet powerful sensor for demanding automation environments.
