The SICK GSE2S-F1311 (Part No. 1064363) is a compact through-beam photoelectric sensor designed for applications requiring speed, precision, and durability in tight installation spaces. Belonging to the G2 series of miniature sensors, it combines advanced optical technology, fast switching performance, and rugged construction, making it a reliable solution for modern industrial automation.

Measuring just 7.7 mm × 21.8 mm × 13.5 mm, the GSE2S-F1311 offers impressive functionality in a small footprint. It provides a through-beam sensing range of up to 2 m, with typical operation around 1.5 m, making it ideal for detecting objects across conveyors, assembly systems, and machinery where space constraints are common. Its dual-component emitter-receiver design ensures dependable detection even under challenging conditions.

Equipped with PinPoint LED technology, the sensor projects a visible red beam at 640 nm, forming a sharply focused light spot measuring approximately 23 mm at 500 mm. This clear and concentrated light beam ensures quick and precise alignment during installation and facilitates accurate detection of objects, regardless of surface finish or shape. The visible beam also helps operators verify sensor positioning during routine maintenance, reducing downtime.

One of the defining features of the GSE2S-F1311 is its fast PNP dark-switching output, which reacts in under 0.6 ms and supports switching frequencies up to 800 Hz. This speed makes it highly effective for dynamic processes such as high-speed packaging lines, robotic handling systems, and automated inspection setups where rapid detection is essential. To guarantee reliability, the output electronics are fully protected against common industrial hazards, including reverse-polarity wiring, electrical interference, over-current loads, and short-circuits.

The sensor’s build quality reinforces its suitability for demanding environments. Constructed from durable ABS housing and rated IP67, the GSE2S-F1311 resists both dust and water ingress, ensuring uninterrupted operation in tough industrial conditions. It operates reliably within a voltage range of 10–30 V DC and across a temperature span from –25 °C to +50 °C, enabling flexibility across diverse machine designs and climates.

Energy efficiency is another advantage of the GSE2S-F1311. It consumes a modest 20 mA of current, making it an energy-conscious choice for integration into large-scale automation systems. At the same time, its switching output supports loads of up to 50 mA, providing dependable electrical performance without compromising efficiency.

In summary, the SICK GSE2S-F1311 combines compact design, visible optical alignment, high-speed dark-switching output, and rugged housing into a sensor built for precision and endurance. It is the ideal choice for engineers and system integrators seeking a through-beam sensor that delivers consistent, high-speed detection in space-restricted environments.
