The SICK GSE2S-P1311 (Part No. 1064362) is a high-performance through-beam photoelectric sensor engineered for compact integration and reliable performance in industrial automation. Part of the G2 series, it combines precise detection capabilities with rugged construction, making it suitable for a wide range of machine and process applications.

Measuring only 7.7 mm × 21.8 mm × 13.5 mm, this miniature sensor provides powerful through-beam sensing in a remarkably small package. Despite its compact size, it offers a sensing distance of up to 2 m, with typical operation around 1.5 m. This allows it to handle long detection paths in tight installation environments, ensuring flexibility in machinery design and system integration.

The GSE2S-P1311 is equipped with PinPoint LED technology, which emits a visible red light at 640 nm. The resulting light spot is sharply defined, measuring around 23 mm in diameter at 500 mm. This crisp beam improves accuracy during object detection and simplifies alignment during setup and maintenance. Operators can easily see and adjust the beam, ensuring proper calibration even in dynamic or visually complex environments.

Speed and responsiveness are central to its performance. With a PNP light-switching output, the GSE2S-P1311 achieves response times under 0.6 ms and supports switching frequencies up to 800 Hz. This makes it ideal for fast-paced applications such as conveyor monitoring, packaging systems, or robotic handling, where rapid detection is critical to maintaining throughput and process reliability.

In addition to speed, the sensor integrates comprehensive electronic protections. It is safeguarded against reverse-polarity connections, electrical interference, over-current, and short-circuit conditions. These protective features enhance long-term reliability and reduce the risk of failures that could interrupt production.

The sensor’s housing is built from durable ABS plastic and rated IP67, offering robust resistance to dust, water ingress, and harsh industrial conditions. With an operating voltage range of 10–30 V DC and a temperature tolerance from –25 °C to +50 °C, it is capable of performing consistently in demanding environments.

Energy efficiency further strengthens its suitability for large systems. The sensor consumes only around 20 mA of current, while supporting output loads up to 50 mA. This balance of low consumption and reliable switching capacity ensures efficient integration into automation networks without sacrificing performance.

In summary, the SICK GSE2S-P1311 provides a perfect blend of compact design, long through-beam range, fast response, and rugged construction. It is an excellent choice for machine builders, integrators, and automation engineers seeking a space-saving yet powerful sensor solution for high-speed, high-reliability applications.
