In large-scale distribution facilities, boxes of varying sizes move swiftly on conveyor belts. The GRL18S-P2436 ensures reliable package detection even when objects are far from the sensor. Its 7.2 m sensing range and polarization filter prevent false signals from shiny tapes or uneven surfaces. The fast 500 µs response time keeps pace with high-speed conveyors, reducing misreads and improving automated sorting efficiency. Its compact M18 housing allows installation in narrow conveyor sections without interfering with material flow, making it a dependable choice for logistics automation.
In packaging machinery, the sensor helps verify whether flaps, labels, or product edges are correctly positioned before sealing or labeling. The visible red PinPoint LED provides an easy alignment reference during setup, while the retro-reflective dual-lens system ensures stable detection of glossy materials like coated cardboard or film wraps. Its IP67-rated construction protects against moisture and dust from adhesives or product residue, reducing unplanned downtime and ensuring continuous, precise operation in high-volume packaging lines.
During automotive production, metal brackets or panels often reflect strong light, making optical sensing difficult. The GRL18S-P2436 overcomes this with its polarization filtering and dual-lens precision, reliably detecting reflective metal parts on conveyors or robotic assembly stations. Its 1 kHz switching frequency captures rapid part movement without signal loss. The robust ABS housing resists vibration and mechanical stress, while its complementary PNP output allows easy integration with automated control systems in manufacturing lines.
At industrial sites or warehouses, automated doors and vehicle gates need consistent detection in dusty or outdoor environments. The GRL18S-P2436 provides accurate vehicle or object sensing with a long detection range and strong resistance to environmental light changes. The sealed IP67 enclosure prevents moisture intrusion, while the visible LED assists with quick visual alignment during installation. This combination of rugged design and precision sensing ensures smooth, reliable gate operation and enhanced safety in high-traffic zones.
