GL-R72H Keyence Safety Light Curtain – Large-Scale Hand Protection
The GL-R72H is a high-capacity safety light curtain from the Keyence GL-R Series, designed to provide an expansive safety barrier for tall machinery and wide access points. Featuring 72 high-intensity infrared beams and a 25 mm beam pitch, this unit is specifically optimized for hand protection. It meets the most stringent international safety requirements, including Type 4, SIL3, and PLe, making it a cornerstone for safety in heavy industrial automation.
Full-Height Sensing with No-Blind-Zone Design
The GL-R72H utilizes Keyence’s unique «No-Blind-Zone» technology. Unlike standard light curtains that have dead space at the ends of the housing, the sensing area of the GL-R72H reaches the very top and bottom of the unit. This allows for a continuous 1420 mm protective height, enabling seamless installation into machine corners without the need for additional shielding or overlapping units to cover gaps.
