KEYENCE GL-R Series Safety Light Curtains Deliver Modular, All-Round Machine Safeguarding for Global Smart Manufacturing
Industry News | Automation Safety & Sensors Sector, July 2026
OSAKA, Japan – July 3, 2026 – KEYENCE Corporation, a global leader in industrial automation sensors and safety components, reinforces its Type 4 safety light curtain portfolio with the full lineup of GL-R series models including GL-RP5N cable assembly, GL-RB01/GL-RB21 mounting brackets, finger-protection GL-R63F, and a complete spectrum of hand-protection variants: GL-R08H, GL-R12H, GL-R24H, GL-R32H, GL-R40H, GL-R52H. The unified modular solution addresses diversified safeguarding demands across automotive, electronics assembly, packaging, metalworking and robotic workstation applications, complying with IEC 61496, ISO 13849 PL e and global regional machinery safety standards.
Comprehensive Model Matrix Covers All Protection Height Requirements
The GL-R family splits into two core detection grades to match different risk isolation scenarios:
- Finger-protection GL-R63FAdopts 14 mm minimum detectable object resolution with 63 optical axes, delivering full finger injury prevention for precision press equipment, semiconductor handler stations and miniature component assembly lines. Its zero-dead-zone optical structure eliminates blind spots along the entire protection height, removing traditional light curtain coverage gaps that create hidden safety hazards on compact machinery frames基恩士. Detection range stretches from 0.2 m up to 10 m, supporting narrow-space installation on bench-top automated tools.
- Hand-protection GL-RH Series (GL-R08H / GL-R12H / GL-R24H / GL-R32H / GL-R40H / GL-R52H)Standardized 25 mm detection resolution for hand and arm protection, covering ultra-short to extended protection heights:
- GL-R08H: 8 axes, 160 mm total length, ideal for small injection molds and compact test fixtures
- GL-R12H: 12 axes, 240 mm length, suited for mini conveyor entry/exit safety barriers
- GL-R24H: 24 axes, 480 mm length, widely deployed on desktop robotic cells
- GL-R32H: 32 axes, 640 mm length, mainstream solution for mid-size stamping machines
- GL-R40H: 40 axes, 800 mm length, matches medium automated assembly lines
- GL-R52H: 52 axes, 1040 mm length, designed for large robotic welding and palletizing workcells
All GL-RH units feature a maximum 15 m long-distance sensing capability, allowing flexible layout design for spacious factory automation zonesKEYENCE DE....
Matching Accessories Simplify On-Site Integration & Installation
KEYENCE completes the system with dedicated supporting hardware to cut wiring and assembly downtime for system integrators:
- GL-RP5N: Standard 5-meter synchronized connection cable (PNP/NPN configurable), integrating transmitter and receiver wiring with simplified terminal layout to reduce wiring errors and cabinet space occupation; supports both wire synchronization and optical synchronization modes for multi-curtain parallel setup without mutual light interference基恩士.
- GL-RB01 & GL-RB21 Universal Mounting Brackets: Heavy-duty metal adjustable brackets with multi-angle positioning function. GL-RB01 is a compact single-point mount for narrow frames, while GL-RB21 dual-side brackets deliver stable fixation for long-length GL-R52H and GL-R63F units, resisting vibration from high-speed production equipment.
Core Technical Advantages for Harsh Industrial Environments
The entire GL-R series inherits KEYENCE’s rugged industrial design to lower long-term maintenance costs:
- Robust all-aluminum housing with dual shock buffer structure, capable of withstanding wrench impact, machine vibration and accidental collision on production floors基恩士; IP65/IP67 dust and waterproof rating adapts to coolant splashing, dust-laden metal processing and humid food packaging workshops.
- Real-time multi-color status indicator lights embedded on both transmitter and receiver, displaying beam blockage, power failure and synchronization faults at a glance for rapid troubleshooting.
- Optimized response time minimizes machine cycle loss during safety trigger; built-in EDM monitoring and restart interlock functions remove the need for extra auxiliary safety relays in most standard configurations.
- Support series connection of multiple light curtains via internal wiring channels, reducing the number of safety controllers required for multi-station linked production lines.
Market Application Value & Industry Trend Alignment
Against the backdrop of tightening global workplace safety regulations and booming Industry 4.0 smart factory transformation, modular safety light curtains have become mandatory standard equipment for new automated production lines. End-users face pain points including inconsistent mounting hardware, limited protection height options and complicated wiring when mixing different safety sensor brands. KEYENCE’s one-stop GL-R package (main curtains + dedicated cables + customized brackets) enables system integrators to standardize component procurement, shorten machine design cycles and unify after-sales maintenance standards.
Automotive OEMs, 3C electronics manufacturers and logistics automation system builders have widely adopted this full model lineup in mass production. For collaborative robot workstations, the combination of short GL-R08H/GL-R12H and long GL-R52H creates layered safety zones to distinguish low-risk material passing areas and high-risk robotic operation zones, balancing operator safety and production efficiency.
KEYENCE Global Sales & Technical Support
All listed GL-R models (GL-RP5N, GL-RB01, GL-RB21, GL-R63F, GL-R52H, GL-R40H, GL-R32H, GL-R24H, GL-R12H, GL-R08H) are available for immediate delivery across Asia Pacific, Europe and North America. KEYENCE’s local engineering teams provide free on-site layout simulation, wiring scheme design and safety compliance verification to help manufacturers pass ISO and CE machinery safety audits smoothly.
Industry analysts point out that integrated, fully matched safety sensor kits will become a mainstream development direction for the industrial safety component market in the next five years. KEYENCE’s complete GL-R modular ecosystem sets a benchmark for standardized, high-reliability machine safeguarding solutions for automated manufacturing worldwide.
