The SICK GSE2S-N1311 (Part No. 1064365) is a compact through-beam photoelectric sensor designed for reliable detection in industrial environments where space, precision, and durability are essential. Belonging to the miniature G2 series, it combines advanced optical sensing, fast response electronics, and rugged housing into a sensor that is both space-efficient and performance-driven.

Measuring just 7.7 mm × 21.8 mm × 13.5 mm, the GSE2S-N1311 is one of the smallest photoelectric sensors in its class. Despite its small footprint, it offers a sensing distance of up to 2 m, with a typical range of 1.5 m, making it highly effective for applications involving conveyors, packaging lines, robotic systems, and automated assembly processes. Its compact size allows engineers and integrators to install it in confined spaces without sacrificing detection reliability.

At the core of its performance is PinPoint LED technology, which projects a bright and visible 640 nm red beam. The beam forms a precisely defined spot of about 23 mm at 500 mm, making it easy to align the emitter and receiver during installation. This feature significantly reduces setup time and ensures long-term detection accuracy, even when operating in environments with limited visibility or complex machine layouts.

The NPN light-switching output is engineered for speed and responsiveness. With a reaction time of less than 0.6 ms and the ability to operate at switching frequencies up to 800 Hz, the sensor is well-suited for dynamic, high-speed applications. It enables precise detection of fast-moving objects, ensuring smooth operation in demanding automation processes. To enhance reliability, the electronics are safeguarded against reverse-polarity wiring, electrical interference, overload, and short-circuit conditions, minimizing downtime and extending service life.

The robust ABS housing is rated IP67, providing excellent protection against dust and water ingress. This makes the GSE2S-N1311 ideal for environments where moisture, particulate matter, or cleaning processes are common. It operates within a supply voltage range of 10–30 V DC and a temperature range of –25 °C to +50 °C, ensuring adaptability across diverse industrial conditions.

Efficiency is also a hallmark of its design. With a low current consumption of approximately 20 mA, it integrates seamlessly into energy-conscious automation systems. At the same time, its output can reliably switch loads up to 50 mA, balancing low power usage with dependable electrical performance.

In conclusion, the SICK GSE2S-N1311 is a compact, fast, and durable through-beam sensor built for high-precision detection in space-limited industrial applications. With visible PinPoint alignment, rugged housing, and high-speed NPN output, it offers a reliable and efficient solution for machine builders, system integrators, and automation engineers seeking performance in miniature form.
