The SICK GTB2S-F5311 is a compact and efficient photoelectric proximity sensor engineered for precise object detection in demanding industrial applications. Part of the proven SICK G2 series, it employs advanced background suppression technology in combination with a PinPoint red LED light source. This setup ensures reliable detection of objects from 8 mm to 100 mm, delivering stable performance even in conditions where background reflectivity could otherwise interfere with accuracy. The clearly visible red light also simplifies sensor alignment during installation and maintenance.

The GTB2S-F5311 is built for environments where space is limited but durability is essential. Measuring only 7.7 mm wide, 21.8 mm high, and 13.5 mm deep, its ultra-compact rectangular housing fits easily into tight spaces on machinery or automated systems. Despite its small footprint, the sensor maintains a rugged design, constructed from ABS housing material with PMMA optics. It is rated to IP67, ensuring reliable operation against dust ingress and water exposure, making it a dependable choice for both standard and challenging production environments.

In terms of performance, the GTB2S-F5311 excels in high-speed applications. It features a fast response time of under 0.6 ms and supports switching frequencies up to 800 Hz, enabling it to detect rapidly moving objects with precision. This makes it especially useful in automation processes such as conveyor monitoring, robotic handling, and packaging systems, where timing and reliability are critical. The sensor is equipped with an NPN light-switching output, which integrates seamlessly with existing industrial control systems.

Ease of integration is further enhanced by its fixed sensitivity design, which eliminates the need for manual adjustment or calibration. This plug-and-play approach reduces installation time and ensures consistent detection performance across multiple devices or systems. The sensor operates on a 10–30 V DC power supply, consuming around 20 mA, making it both energy-efficient and straightforward to implement.

To protect both itself and the connected automation system, the GTB2S-F5311 includes comprehensive protective circuitry, such as short-circuit protection, reverse polarity protection, and overcurrent safeguards. Additionally, it offers an exceptionally long operational reliability with a Mean Time to Dangerous Failure (MTTF_D) exceeding 3,000 years, ensuring confidence in long-term deployments.

In conclusion, the SICK GTB2S-F5311 combines compactness, robust durability, fast response, and ease of use. It is ideally suited for industries that require reliable short-range detection in tight installation spaces, including packaging, electronics assembly, conveyor automation, and robotics.
