G2 is available in both slim and flat housing versions, allowing easy integration into compact machines and installations with very limited mounting space. This provides a wide range of application possibilities.
- With the dual-lens system and polarization effect, the sensors ensure reliable object detection. G2 photoelectric sensors can be installed quickly and easily, improving overall user-friendliness.
Product Overview – GL2S-N0311S03 Photoelectric Sensor
The GL2S-N0311S03 is a miniature retro-reflective photoelectric sensor belonging to SICK‘s G2 product family. It employs a dual-lens optical system to minimize the required minimum distance to the retroreflective target, enabling reliable object detection across a broad operating range from 30 mm to 2,500 mm (typical) and up to 3,000 mm (maximum) when used with the PL40A reflector. The integrated polarization filter suppresses false triggering caused by shiny or reflective object surfaces, ensuring consistent switching performance in demanding industrial environments.
5 Key Specifications:
- Sensing range: 0.03 m – 2.5 m (typical), up to 3 m maximum (PL40A reflector)
- Switching output: NPN, light/dark selectable switching mode
- Light source: PinPoint LED, 640 nm red light, 100,000-hour average service life at +25 °C
- Enclosure rating: IP67 – complete dust ingress protection and temporary water immersion

Industrial Applications – GL2S-N0311S03 Photoelectric Sensor
With its 3 m sensing range, NPN discrete output, and IP67-rated enclosure, the GL2S-N0311S03 is suited for a broad range of industrial automation applications:
- Conveyor systems and sortation lines: The 800 Hz switching frequency and < 0.6 ms response time enable reliable high-speed object detection on production conveyors. The Ø 11 mm PinPoint LED light spot ensures precise detection of small components.
- Food and pharmaceutical packaging lines: IP67 ingress protection withstands regular washdown procedures and dusty processing environments. The 3 m sensing range accommodates flexible conveyor layouts with varying installation distances.
- Automated industrial doors and access gates: Detects personnel or vehicles at distances up to 3 m, supporting safe and reliable actuation logic. The compact 7.7 x 21.8 x 13.5 mm housing integrates readily into door frame assemblies.
- Automotive and electronics manufacturing: The visible red light beam (640 nm) facilitates optical alignment during installation and commissioning. The integrated polarization filter eliminates cross-talk from metallic or glossy workpiece surfaces.
- Warehouse automation and intralogistics: NPN output signal is directly compatible with the majority of industrial PLCs and motion controllers deployed in Vietnam. Suitable for object counting, positioning, and product verification tasks.
AUMI has supplied GL2S-series sensors to multiple industrial automation projects across Vietnam, including electronics manufacturing plants, food packaging lines, and automated warehouse systems.
