SICK GL6G Series Photoelectric Sensors: Compact Retro-Reflective Sensors for Industrial Automation | Technical Specifications​

​Product Overview​

The SICK GL6G series is a family of ​retro-reflective photoelectric sensors​ designed for precise object detection in compact industrial applications. Housed in a miniature enclosure (12 mm × 31.5 mm × 21 mm), these sensors leverage PinPoint LED technology and SICK ASIC to deliver reliable performance with a detection range of up to 6 meters. With IP67 protection, metal-threaded inserts, and dual-lens systems, they are suited for logistics, packaging, and material handling environments .

​Technical Specifications​

​Key Features​

1. ​PinPoint LED Technology: Generates a bright, visible red spot for precise alignment and detection of objects, including transparent materials like glass or film .

2. ​SICK ASIC Integration: Embeds proprietary circuitry for enhanced noise immunity, stability, and resistance to crosstalk, ensuring consistent performance in electrically noisy environments .

3. ​Compact and Durable Design: Metal-threaded inserts enable secure mounting with standard M3 screws, while the IP67-rated housing resists dust, moisture, and mechanical stress .

4. ​User-Friendly Configuration: Features a 270° potentiometer for sensitivity adjustment and bright LED indicators for status monitoring, simplifying setup and maintenance .

5. ​Polarization Filter: Suppresses false triggers from reflective surfaces by detecting only polarized light from approved reflectors (e.g., PL80A) .

​Application Scenarios​

• ​Logistics and Conveyor Systems: Detects packages, pallets, or containers on conveyor belts, ensuring accurate positioning and jam prevention in warehouses .

• ​Transparent Object Detection: Identifies glass bottles, plastic films, or transparent packaging in food, beverage, and pharmaceutical production lines .

• ​Automated Guided Vehicles (AGVs)​: Monitored load presence and positioning on AGVs, with resilience to vibration and ambient light interference .

• ​Access and Safety Systems: Secures gates, doors, or machinery by detecting personnel or obstacles in hazardous zones .

• ​Packaging Machinery: Verifies label application, fill levels, or box sealing with high-repeatability switching .
