The SICK GSE2S-P5311 (Part No. 1064364) is a compact through-beam photoelectric sensor engineered to deliver high-performance detection in confined spaces. As part of the G2 series, this sensor combines precise optics, fast response times, and rugged construction, making it an excellent choice for industrial automation applications that demand both reliability and durability.

With dimensions of just 7.7 mm × 21.8 mm × 13.5 mm, the GSE2S-P5311 offers powerful detection capabilities within an exceptionally small housing. Its through-beam design allows sensing distances of up to 2 m, providing reliable object detection even across wider gaps. This makes it particularly effective for use on compact machinery, conveyors, or automated assembly lines where installation space is restricted but dependable performance is essential.

The optical system of the sensor is built around PinPoint LED technology, which operates at 640 nm. This visible red beam produces a bright and sharply defined spot, measuring approximately 23 mm at 500 mm, ensuring rapid and precise alignment of the emitter and receiver during setup. The clearly visible spot not only improves installation accuracy but also helps technicians perform quick inspections or adjustments during operation.

Performance is further enhanced by the fast PNP light-switching output, which achieves a response time of less than 0.6 ms and allows switching frequencies up to 800 Hz. This enables the sensor to handle high-speed applications such as packaging lines, robotics, and automated handling processes where rapid detection of objects is critical to maintaining production efficiency. To ensure long-term operational reliability, the sensor’s electronic system is protected against common electrical risks, including reverse-polarity connections, electrical noise, overload conditions, and short-circuits.

Durability is a defining characteristic of the GSE2S-P5311. Its housing is made from robust ABS plastic and rated IP67, ensuring strong resistance to dust, dirt, and water ingress. The sensor operates effectively across a supply voltage range of 10–30 V DC and within a temperature range from –25 °C to +50 °C, making it adaptable to a variety of industrial environments.

Energy efficiency is also built into the design. With a typical current consumption of around 20 mA and the ability to handle output loads up to 50 mA, the sensor minimizes energy demands while still providing reliable electrical performance.

In summary, the SICK GSE2S-P5311 delivers compact, fast, and precise through-beam detection in a rugged and reliable package. Its combination of visible optical alignment, rapid response time, and protective housing makes it a trusted solution for machine builders, integrators, and engineers seeking dependable sensing technology for modern automation systems.
