The SICK GL2S-P1311 (Part No. 1064357) is a high-performance miniature photoelectric retro-reflective sensor designed for industrial automation environments where space, precision, and reliability are key. Belonging to the G2 series, this sensor is engineered for demanding applications where consistent detection is required, even under harsh conditions.

At only 7.7 mm × 21.8 mm × 13.5 mm, the GL2S-P1311 is exceptionally compact, making it suitable for installations where mounting space is limited. The sensor features a dual-lens retro-reflective design, which provides stable object detection at minimal distances from the reflector, allowing it to be used in tight machine layouts and restricted mounting locations.

A standout feature of the GL2S-P1311 is its PinPoint LED technology. The sensor emits a visible red light beam at 640 nm, creating a small and sharply defined spot of approximately 11 mm in diameter at a 250 mm distance. This makes alignment simple and ensures accurate detection of small or irregularly shaped objects. By providing a clearly visible beam, the sensor reduces setup time and improves detection reliability.

Performance is another strong point of the GL2S-P1311. It offers a PNP light-switching output with a very fast response time of less than 0.6 ms, achieving a maximum switching frequency of 800 Hz. This high-speed performance ensures reliable detection of rapidly moving objects, making it ideal for conveyor systems, packaging machinery, and robotic applications. Built-in protection against reverse polarity, interference, over-current, and short circuits enhances long-term reliability and minimizes downtime in production environments.

The sensor’s housing is made from robust ABS plastic and is rated IP67, providing protection against dust ingress and water immersion. Combined with its wide operating voltage range of 10–30 V DC and ability to perform reliably in temperatures from –25 °C to +50 °C, the GL2S-P1311 is well-suited for challenging industrial conditions. Additionally, its integrated polarization filter minimizes the effects of unwanted reflections, further enhancing detection accuracy in reflective or cluttered environments.

With a low current consumption of just 20 mA and the ability to handle switching loads of up to 50 mA, the sensor is energy efficient while still delivering robust performance. Its compact size, rugged build, and advanced optical technology make it a dependable choice for engineers seeking a balance of precision and durability in their automation systems.

In summary, the SICK GL2S-P1311 is a compact, precise, and reliable sensor designed to provide high-speed detection in space-constrained environments. Its visible LED spot, rugged construction, and protective features make it an excellent solution for industrial automation, robotics, and material handling applications where accuracy and durability cannot be compromised.
