Available. GL-R44H-T + GL-R44H-R. The Keyence GL-R44H-T and GL-R44H-R are components of the GL-R series safety light curtains, designed to provide hand protection in industrial environments. The GL-R44H-T is the transmitter unit, and the GL-R44H-R is the receiver unit, each featuring 44 optical axes for comprehensive detection coverage. These units are suitable for applications requiring high-resolution safety measures, such as machine guarding and automated processes. Key features include a detection capability of ø25 mm, a total length of 880 mm, and a detection height of 860 mm. The effective detection distance ranges from 0.2 to 15 meters, with an effective aperture angle of ±2.5° when the operating distance is 3 meters or more. The light source is an infrared LED operating at 870 nm, ensuring reliable performance in various lighting conditions. The response time for the optical synchronization system (Channel A or B) is 12.9 ms for ON→OFF and 58.2 ms for OFF→ON transitions. These specifications make the GL-R44H-T and GL-R44H-R units ideal for enhancing safety in automated industrial settings.
