The Sick GL6G-P1212 Photoelectric Sensor operates on a dual-lens retro-reflective sensing principle using a PinPoint LED that emits visible red light at 650 nm. It provides dependable object detection across a sensing range of up to 5 meters, with a maximum distance of 6 meters. The 8 mm light spot at 350 mm ensures accurate alignment with reflectors and allows stable operation even with small, shiny, or transparent targets.
This photoelectric sensor features a PNP digital output and supports both light-on and dark-on switching via a user-selectable switch. Engineers can fine-tune the sensing field using the built-in 270Β° potentiometer. The GL6G-P1212 sensor delivers rapid switching with a response time under 625 Β΅s and supports a high-frequency output of 1,000 Hz, making it suitable for high-speed production lines. Operating at 10 V DC to 30 V DC with a low current consumption of 30 mA, it is optimized for energy-efficient, continuous automation tasks.
Encased in a rugged ABS/PC rectangular housing (12 mm Γ 31.5 mm Γ 21 mm), the GL6G-P1212 Photoelectric Sensor includes a standard 3-wire, 2-meter cable for easy electrical connection. The PMMA front screen and IP67 protection rating ensure dust-tight, waterproof operation in harsh industrial environments. It operates reliably between β25 Β°C and +55 Β°C, weighs just 60 g, and is widely adopted across packaging, material handling, and machine automation sectors.
The Sick GL6G-P1212 Photoelectric Sensor is ideal for mid-range object detection in applications where reflector-based sensing is preferred. It is widely used in labeling machines, carton detection, bottle filling lines, and compact conveyors where fast and accurate object sensing is critical.
Its dual-lens retro-reflective design ensures consistent operation even when target surfaces vary in reflectivity or transparency. The visible red light and adjustable sensitivity allow for quick setup and alignment during installation. Maintenance engineers can easily adjust the sensing threshold using the potentiometer, ensuring reliable operation without the need for complex calibration.
For engineers and students alike, the GL6G-P1212 photoelectric sensor represents an efficient solution that blends robust design with high-performance optics. Whether you're integrating it into a new automation system or replacing a legacy sensor, this Sick photoelectric sensor delivers precise detection, fast switching, and long-lasting reliability in industrial environments.
