The Sick GL2S-E1311 (1063009) is a compact, high-performance photoelectric retro-reflective sensor developed to meet the needs of modern industrial automation. Its small size, rapid response, and durable housing make it ideal for use in space-constrained environments where reliable detection is essential.

At its core, the GL2S-E1311 incorporates a dual-lens optical system that enables short minimum sensing distances of just 0.03 m while maintaining a typical range of 2.5 m and extending up to 3 m with a suitable reflector. This combination of close-up precision and extended reach ensures flexibility across a wide variety of applications.

The sensor uses a visible red PinPoint LED at 640 nm, which projects a bright, sharply defined light spot measuring approximately 11 mm at 250 mm distance. This clear and concentrated spot greatly simplifies alignment during installation, allowing operators to quickly and accurately position the sensor without trial and error. The focused beam also enhances detection reliability, even when working with small or reflective objects.

Electrically, the GL2S-E1311 is equipped with an NPN transistor output in dark-ON mode. It offers high-speed switching capabilities with a maximum frequency of 800 Hz and a rapid response time of less than 0.6 ms. These attributes make the sensor particularly effective in fast-moving processes, such as packaging machinery, automated conveyors, or robotic pick-and-place operations, where precision and speed are both critical.

From a mechanical standpoint, the GL2S-E1311 is engineered to deliver robust performance despite its ultra-compact form factor. Measuring only 7.7 × 21.8 × 13.5 mm and weighing around 34 g, it fits easily into tight installations. The sensor housing is constructed from durable ABS and PMMA materials, earning it an IP67 protection rating, which ensures resistance to dust and water ingress. Its wide operating temperature range of –25 °C to +50 °C makes it suitable for demanding industrial environments.

Additional features further enhance its reliability. The sensor includes built-in short-circuit protection, reverse-polarity protection, and interference suppression to safeguard both the sensor and connected systems. A 2 m PVC cable with a 3-wire connection provides a simple and secure interface for integration into control systems.

In summary, the Sick GL2S-E1311 combines precision optics, high-speed electronic performance, and rugged mechanical construction in a remarkably compact package. It is an excellent choice for automation engineers and system integrators seeking a space-saving, high-reliability sensor that can keep pace with today’s fast and precise manufacturing requirements.
