The Sick GSE2S-E1311 (1063070) is a compact through-beam photoelectric sensor designed to deliver high-performance object detection in space-restricted industrial environments. By separating the emitter and receiver into different housings, the sensor achieves highly reliable detection even in challenging conditions, ensuring consistent performance across a wide range of automation tasks.

This model is engineered to detect objects over distances of up to 2 m, with a typical operating range of 1.5 m. Thanks to its through-beam design, the sensor maintains excellent accuracy even when handling small, shiny, or partially transparent objects that can cause difficulties for other sensing principles. Its versatility makes it ideal for use in automated conveyor systems, packaging equipment, and robotics, where precision detection is critical.

The optical system of the GSE2S-E1311 employs a visible red PinPoint LED operating at a wavelength of 640 nm. The LED produces a sharply defined, concentrated light spot approximately 23 mm in diameter at 500 mm distance. This feature not only simplifies installation and alignment but also ensures reliable detection performance by reducing errors caused by stray reflections or misalignment.

Electrically, the sensor is designed for high-speed industrial use. It is equipped with an NPN output configured in dark-ON mode, providing a fast response time of less than 0.6 ms and capable of switching frequencies up to 800 Hz. These specifications allow it to operate effectively in dynamic environments such as high-speed production lines, where rapid detection and output reliability are essential for smooth operations.

The mechanical design reflects the need for compactness and resilience. The GSE2S-E1311 measures only 7.7 × 21.8 × 13.5 mm, allowing it to be mounted in tight spaces without compromising performance. Constructed from durable ABS material, the housing is lightweight yet robust, providing excellent resistance to wear. With an IP67 protection rating, the sensor is safeguarded against dust and water ingress, ensuring stable operation in demanding industrial settings. Its operating temperature range of –25 °C to +50 °C further enhances its adaptability, allowing it to perform reliably in diverse environments.

The sensor also incorporates protective circuitry such as reverse polarity protection, short-circuit protection, and interference suppression. These safeguards ensure long service life and stable performance, even under electrically noisy or harsh operating conditions. The unit is supplied with a standard 2 m PVC cable, offering straightforward integration into existing control systems.

In conclusion, the Sick GSE2S-E1311 combines through-beam precision, high-speed electronics, rugged mechanical construction, and compact design in a single package. Its combination of performance and durability makes it an ideal solution for automation engineers looking to implement reliable object detection in fast, space-constrained, and demanding industrial environments.
