The Keyence GL-R31F is a fine-resolution safety light curtain engineered to deliver precise and dependable safeguarding in compact industrial applications. With its 31-beam configuration, ultra-fine √∏14 mm detection capability, and extended protective coverage, the GL-R31F provides a high level of safety where operator hand or finger protection is critical.

A standout feature of the GL-R31F is its fine detection capability, able to sense objects as small as 14 mm (0.55″) in diameter. This makes it suitable for applications requiring high levels of protection, such as preventing hand or finger intrusion into hazardous zones. Its fine resolution ensures that even small-scale intrusions are captured reliably, offering peace of mind in industries where precision and operator safety cannot be compromised.

The unit is built with a 31-beam arrangement, creating a dense detection grid with minimal spacing between beams. This configuration ensures consistent protection across the entire coverage area, reducing the risk of blind spots and guaranteeing dependable safety performance. With such density, the GL-R31F provides accuracy and stability well-suited for high-risk environments where operators work close to machinery.

The GL-R31F offers a detection height of 300 mm (11.81″), making it effective for small- to medium-sized machine openings and work areas. To enhance safety further, the protection zone extends to 324 mm (12.76″), adding an extra buffer that minimises the chance of accidental bypass. This layered approach to protection makes it ideal for securing compact but critical access points.

Despite offering fine detection and high-density beam coverage, the GL-R31F maintains a compact total length of just 320 mm (12.60″). Its space-efficient design allows for straightforward installation in machinery with restricted layouts, making it an excellent choice for equipment upgrades or new designs where space is at a premium.

Built as part of the GL-R Series, the GL-R31F combines precision with rugged durability. Its housing is engineered to withstand industrial challenges such as vibration, dust, and environmental stress, ensuring reliable long-term performance. This robust construction minimises maintenance needs and supports consistent safety compliance.

The GL-R31F is suitable for a wide range of applications. In electronics manufacturing, it ensures operators are safeguarded when working near compact assembly stations. In packaging, it protects operators during manual interaction with equipment. In automotive and metalworking industries, it provides reliable protection around presses, fixtures, or smaller automation tools.

In summary, the Keyence GL-R31F is a compact, fine-resolution safety light curtain designed to deliver high-density protection in space-limited environments. With its ability to detect √∏14 mm objects, 31-beam layout, 300 mm detection height, and durable 320 mm housing, it offers manufacturers a reliable and precise safeguarding solution. For industries requiring dependable finger- and hand-level safety in compact applications, the GL-R31F is an excellent choice.
