The SICK GL2S-F1311 (Part No. 1064358) is a miniature photoelectric retro-reflective sensor from the G2 series, engineered to deliver precision detection in compact spaces while maintaining ruggedness and reliability. With its high-performance optical system, fast response capabilities, and durable housing, the GL2S-F1311 is a trusted solution for industrial automation environments where accuracy and space efficiency are crucial.

Compact in size at just 7.7 mm × 21.8 mm × 13.5 mm, this sensor is specifically designed for machinery and applications where installation space is limited. Its dual-lens retro-reflective design allows for stable detection even at minimal distances from the reflector, making it highly versatile for close-range setups and confined layouts.

Equipped with PinPoint LED technology, the GL2S-F1311 projects a visible red light beam at 640 nm, forming a small, sharply defined spot of about 11 mm in diameter at 250 mm. This concentrated beam ensures precise detection of small, shiny, or irregularly shaped objects while also simplifying sensor alignment during installation and maintenance.

From a performance perspective, the GL2S-F1311 delivers impressive speed. It features a PNP dark-switching output with a rapid response time of less than 0.6 ms and supports switching frequencies of up to 800 Hz. This makes it ideal for use in high-speed automation systems such as packaging, robotics, conveyor lines, and other environments where objects move quickly and detection accuracy cannot be compromised.

Reliability is reinforced by integrated protective circuits, including safeguards against reverse polarity, electrical interference, over-current, and short circuits. These built-in protections ensure long-term operational stability and reduce the likelihood of unexpected downtime.

The housing of the GL2S-F1311 is constructed from durable ABS plastic and rated IP67, providing robust resistance against dust ingress and water exposure. Combined with a wide operating voltage range of 10–30 V DC and an operational temperature span from –25 °C to +50 °C, the sensor is designed to withstand tough industrial conditions without compromising performance.

With a low current draw of only 20 mA and the capability to switch loads up to 50 mA, the GL2S-F1311 strikes an excellent balance between energy efficiency and robust functionality. The inclusion of a polarization filter further enhances detection reliability by suppressing unwanted reflections, ensuring accurate results even in reflective or cluttered optical environments.

In conclusion, the SICK GL2S-F1311 is a compact yet powerful photoelectric sensor that combines high-speed detection, precision optics, and rugged durability. It is particularly well-suited for applications in automation, robotics, and material handling where space is limited and reliable performance is a must.
