The Sick GL2S-F5311 (1063008) is a high-precision, retro-reflective photoelectric sensor that excels in compact automation environments. Designed to combine reliable detection with a very small footprint, this sensor is a dependable solution for space-constrained applications requiring fast and accurate object recognition.

Its optical performance sets it apart in its class. With a dual-lens system, the GL2S-F5311 achieves a very short minimum detection range of only 0.03 m while extending to a typical operating distance of 2.5 m, and a maximum of 3 m when paired with the appropriate reflector. This wide operating span makes it versatile for applications that demand both short-distance precision and moderate-range detection.

The sensor uses a visible red PinPoint LED with a wavelength of 640 nm. The focused beam produces a small, highly accurate light spot of approximately 11 mm diameter at 250 mm distance. This clear, precise beam greatly simplifies setup and alignment, ensuring users can install and configure the sensor quickly and with confidence in its accuracy.

From an electrical standpoint, the GL2S-F5311 is equipped with a PNP transistor output operating in dark-ON mode. It delivers a rapid response time of less than 0.6 ms and can switch at frequencies up to 800 Hz. This high-speed performance allows it to excel in dynamic industrial environments such as packaging, pick-and-place automation, or high-speed conveyor lines where objects move quickly and precise detection is critical.

Mechanically, the sensor is built with durability in mind despite its tiny dimensions. Measuring just 7.7 mm × 21.8 mm × 13.5 mm and weighing only 17.5 g, the unit is small enough for tight integration into machinery. Its ABS and PMMA housing materials provide resilience, while the IP67 protection rating ensures resistance against dust and water ingress. It maintains reliable performance within operating temperatures ranging from –25 °C to +50 °C, making it suitable for a wide variety of indoor and semi-protected industrial settings.

Additional protective features include short-circuit protection, reverse polarity protection, and electrical interference safeguards, which enhance reliability and reduce risks in demanding environments. The sensor is also fitted with a polarization filter to maintain detection integrity, even when reflective surfaces could otherwise interfere with operation.

In summary, the GL2S-F5311 delivers an exceptional balance of compact size, fast response, optical precision, and rugged housing. It is especially well-suited to high-speed automated processes, small-part detection, and systems where installation space is limited but uncompromising detection accuracy is required.
