The JUTAI CL Series Safety Light Curtain emerges as a specialized protective sensing solution engineered to safeguard personnel and preserve operational safety across industrial and commercial scenarios—with a sharp focus on industrial automatic doors and garage doors. Its IP67-rated waterproof and dustproof structure, paired with trusted detection technology, forms an invisible protective grid that reacts instantly to unexpected intrusions, warding off pinching accidents, equipment damage, and safety hazards in high-traffic door environments.
This product family offers an extensive range of models with varied lengths and beam configurations, tailored to match the dimensions of different door types and specific safety requirements. Spanning from compact 500mm units for small garage doors to large-scale 2500mm systems for industrial automatic doors, each light curtain is constructed for long-lasting durability, precise detection, and smooth integration with existing door control systems—eliminating compatibility issues for retrofits or new installations.
The CL Series comprises 9 models, featuring two beam configurations (8 beams and 16 beams) and five length options to cover the full spectrum of industrial and garage door applications:
*Actual detection range may vary based on environmental conditions such as sunlight exposure, dust, or humidity.
Certified IP67 waterproof and dustproof, the light curtain excels in harsh door environments—resisting rain, splashes, heavy dust, and industrial debris. Its hermetically sealed aluminum alloy housing endures temporary water submersion and intense dust accumulation, ensuring unwavering performance for outdoor garage doors, dusty warehouse automatic doors, or humid workshop entrances.
Operating reliably within a range of -20℃ to +60℃, with specialized models available for extreme low temperatures down to -25℃. This versatility makes it ideal for cold storage automatic doors, outdoor garage doors exposed to seasonal fluctuations, and industrial doors in temperature-variable facilities.
- Normal Mode: Delivers full-coverage protection across the entire detection area, triggering immediate door reversal or stopping whenever any beam is interrupted. Perfect for high-traffic industrial automatic doors where personnel or objects may accidentally enter the door’s path.
- Blanking Mode: Customized for door gap installations, where sequential beam blocking during normal door closure is expected. This mode eliminates false alarms while retaining protection against unintended intrusions—critical for roller shutter doors and garage doors with overlapping panels.
With 100mm beam spacing, the light curtain can detect objects as small as 50mm, ensuring no potential hazard is overlooked. This level of precision is essential for anti-pinch protection, preventing doors from closing on hands, limbs, or small objects near industrial automatic doors and garage doors.
CE certified and compliant with EN 61496 machinery safety standards, the product meets international safety regulations—guaranteeing reliability and compliance for global deployments, whether for commercial garage doors or industrial facilities operating across borders.
Boasting low power consumption (≤4W), the light curtain reduces long-term operational costs and environmental impact without sacrificing performance. This energy-saving design is ideal for 24/7 operation of industrial automatic doors and frequently used garage doors.
Equipped with standard 5-pole M8 male connectors and adjustable mounting brackets, the product simplifies installation on various door types. Color-coded cables streamline wiring, and the system seamlessly integrates with most door control panels—minimizing setup time for both new installations and retrofits.
LED indicators on both the transmitter and receiver provide clear real-time feedback:
- Transmitter: Steady blue light (normal operation), fast-flashing red light (voltage irregularity: <9V or >28V).
- Receiver: Steady red light (beam blocked/intrusion detected), steady blue light (no obstruction), flashing blue light (alignment required after initial power-on).
This allows for quick troubleshooting and ensures operators can easily verify system status.
- High-Speed Doors: Enables instant stopping or reversal of fast-closing doors in manufacturing plants, distribution centers, and logistics hubs—preventing pinching during rapid operations.
- Roller Shutter Doors: Protects against entrapment in warehouses, retail back entrances, and industrial facilities with frequent door usage.
- Sectional Doors: Provides safety monitoring for large industrial doors in factories and warehouses, covering wide openings with reliable detection.
- Cold Storage Doors: Delivers consistent performance in low-temperature, high-humidity environments, preventing door closure on personnel or equipment.
- Fire Doors: Ensures safe automatic closure during emergencies without endangering personnel near the door’s path.
- Commercial Garage Doors: Offers anti-pinch protection for loading docks, parking garages, and business entrances with high vehicle and pedestrian traffic.
- Residential Garage Doors: Safeguards families, pets, and property by preventing the door from closing on people or objects in driveways.
- Food Processing Plants: Withstands washdown procedures and high humidity for automatic doors in production areas.
- Warehouse and Logistics Centers: Protects personnel and equipment near automated storage and retrieval system doors.
- Automotive Manufacturing Facilities: Shields workers near automated assembly line doors and vehicle entry/exit points.
The CL Series Safety Light Curtain features user-friendly installation tailored to door applications:
- Flexible mounting options for vertical installation on door frames (compatible with industrial automatic doors and garage doors).
- Simple alignment process guided by LED indicators—ensuring precise positioning of the transmitter and receiver.
- Color-coded cables for straightforward wiring to door control systems, with clear warnings to prevent damage (NO/NC must not connect to power supply positive terminals).
- Configurable NO/NC output modes via easy setup procedures, adapting to different door control requirements.
- Blanking mode activation for door gap scenarios, avoiding false alarms during normal door closure.
The system offers comprehensive diagnostic capabilities to resolve common door-related issues:
- Slow-flashing lights after power-on: Realign the transmitter and receiver for proper beam alignment.
- Fast-flashing red light (transmitter): Check power supply voltage (ensure it falls within 9V-28V).
- Light curtain normal but no anti-pinch action: Inspect wiring connections for errors.
- Unable to enter Blanking Mode: Ensure no light leakage during door descent and that the door or obstruction meets the minimum continuous blocking distance.
Routine maintenance is simple:
- Wipe optical lenses with a dry, soft cloth to remove dust or debris.
- Verify alignment periodically, especially after door maintenance.
- Keep connecting cables away from high-voltage or high-current conductors to avoid interference.
- Avoid bending or twisting cables, and protect the receiver from direct sunlight to prevent false triggers.
- Door-Specific Design: Engineered to address the unique safety needs of industrial automatic doors and garage doors, with dual modes to avoid false alarms.
- Rugged Durability: IP67 protection and aluminum alloy housing ensure longevity in harsh door environments—outdoor, dusty, or humid.
- Global Compliance: Meets international safety standards, suitable for worldwide deployment in commercial and industrial settings.
- Easy Integration: Compatible with most existing door control systems, reducing installation time and costs.
- Customization Options: 9 standard models plus specialized low-temperature versions to match any door size or environment.
- Dedicated Support: Comprehensive technical assistance, including installation guidance and troubleshooting for door-specific applications.
