KEYENCE GL-R79F Industrial safety light curtains
Product Description: KEYENCE GL-R79F Safety Light Curtain
The GL-R79F is an industrial safety light curtain from KEYENCE, designed to provide high-level protection for automated machinery. It detects the presence of objects (e.g., human hands, tools) in hazardous areas by emitting and receiving infrared light beams, preventing injuries or equipment damage. This light curtain supports optical/wired synchronization to avoid signal interference in complex industrial environments.
