The SICK GTB2S-F1311 is a miniature, high-performance photoelectric proximity sensor that delivers precise and reliable object detection in compact and fast-moving automation environments. As part of SICK’s G2 series, it features background suppression technology paired with a visible PinPoint red LED, making it capable of identifying small objects with outstanding accuracy. The sensing range extends from 1 mm to 18 mm, reaching up to 31 mm under optimal conditions, providing flexibility for a wide range of short-distance detection applications.

Designed with space efficiency in mind, the GTB2S-F1311 comes in a compact rectangular housing measuring only 7.7 mm wide, 21.8 mm high, and 13.5 mm deep. Its IP67 rating ensures that the sensor can withstand dust, water splashes, and general industrial wear. Constructed from durable ABS plastic with PMMA optics, it maintains strong mechanical resilience while keeping its lightweight and compact profile, which is essential for installations where space is limited.

Performance is where this sensor excels. With a response time of less than 0.6 ms and the ability to handle switching frequencies up to 800 Hz, the GTB2S-F1311 ensures high-speed detection without sacrificing reliability. Its NPN light-switching output integrates easily with industrial control systems, ensuring compatibility across many automation setups. The light-on output configuration is particularly useful for applications that require detection when an object is present in the sensing field.

Ease of use is another highlight of this model. The GTB2S-F1311 features a fixed sensitivity design, eliminating the need for manual adjustments. This simplifies installation and commissioning, ensuring consistent performance across different machines or applications. Operating on a 10–30 V DC power supply, the sensor consumes only around 20 mA, making it energy-efficient while maintaining strong operational reliability.

To safeguard both the sensor and connected equipment, the GTB2S-F1311 is equipped with integrated protection circuitry. This includes reverse polarity protection, short-circuit resistance, and overcurrent protection, all of which enhance system safety and reduce downtime risks. Additionally, with a Mean Time to Dangerous Failure (MTTF_D) exceeding 3,000 years, the sensor offers an exceptionally long service life.

In summary, the SICK GTB2S-F1311 blends compactness, fast response, reliability, and durability into one sensor. It is particularly well-suited for industries that require rapid and precise small-object detection in tight installation spaces, such as packaging machinery, robotics, electronic component handling, and automated inspection systems.
