Safety Light Curtain for Door Gap Protection and Personnel Safety Detection

Core Specifications (Detailed Parameter Table)

Key Functions & Advantages (Clear Points)

1. Door Gap Protection Specialization

• Targets door gap hazards: Prevents pinching of hands, limbs, or objects in the gap during door closure (ideal for roller shutters, fast doors, and automatic doors).
• Blanking Mode support: Blocks the first channel without triggering safety responses, adapting to door gap structures and avoiding false alarms from normal door operation.

2. Reliable Personnel Safety Detection

• 8-beam full coverage: Eliminates safety blind spots in the door area, accurately detecting personnel or objects entering the detection zone.
• Instant response: Triggers door reversal/stopping immediately upon beam interruption, leaving no time lag for high-risk scenarios.

3. Durable & Adaptable Design

• IP67 protection: Withstands dust, water splashes, and temporary immersion, suitable for indoor/outdoor industrial environments.
• Wide temperature range: Operates stably in low-temperature (-20°C) cold storage or high-temperature (+60°C) workshop settings.
• Rugged aluminum alloy shell: Resists mechanical wear, vibration, and corrosion for long-term use.

4. Easy Installation & Configuration

• Color-coded wiring: Simplifies connection without professional guidance (details in Wiring Guide below).
• Adjustable mounting: Matches different door frame structures, with clear mounting hole indicators for quick positioning.
• Configurable output: Supports NO/NC switching via simple operation to adapt to various door control systems.

Wiring Guide (Standardized Table)

Blanking Mode & NC Configuration Steps

1. Power on the device (ensure wiring is correct).
2. Within 1 minute of power-on, touch the receiver’s Green wire to its GND (Black wire) five times.
3. Observe the receiver’s Red light blinking to confirm activation: Yellow wire switches to NC mode, and Blanking Mode is enabled.

Application Scenarios (Targeted List)

• Automatic doors (commercial buildings, industrial workshops)
• Roller shutter doors (warehouses, retail stores, logistics centers)
• Fast doors (production lines, clean rooms, cold storage facilities)
• Industrial access doors (factory workshops, loading docks)
• Lifting equipment doorways (elevators, hydraulic lifts with door structures)

Troubleshooting (Problem-Solution Table)

Usage & Maintenance Caveats (Key Reminders)

• Keep connecting cables away from high-voltage/high-current conductors to avoid interference or damage.
• Regularly wipe the emitter/receiver lenses with a dry, soft cloth to remove dust, oil stains, or condensation (avoids detection failure).
• Do not bend, twist, or pull the cables forcefully; avoid scratching the infrared lenses.
• Prevent direct sunlight or other infrared light sources from shining on the receiver (avoids false triggers).
• Ensure the door or obstruction used for Blanking Mode meets the minimum continuous blocking distance requirement.
