Infrared Safety Sensor Grid for Roller Shutter Doors with Anti-Pinch Protection

Core Specifications (Parameter Table)

Key Advantages (Clear Points)

1. Targeted Anti-Pinch Protection

• Detects hands, limbs, or objects near roller shutter doors, triggering immediate door reversal to prevent pinching accidents.
• 8-beam full coverage eliminates safety blind spots in door openings, adapting to common roller shutter door sizes.

2. Blanking Mode for False Alarm Prevention

• Blocks the first channel without triggering safety responses, adapting to roller shutter door gap structures.
• Avoids unnecessary interruptions during normal door closure while retaining protection against unintended intrusions.

3. Rugged & Environmentally Adaptable

• IP67 protection resists dust, water splashes, and harsh industrial conditions, suitable for indoor/outdoor roller shutter doors.
• Wide temperature range (-20°C ~ +60°C) ensures stable operation in cold storage, workshops, or outdoor settings.

4. Easy Installation & Operation

• Color-coded wiring simplifies connection to roller shutter door control systems (details in Wiring Guide).
• Intuitive LED indicators enable quick status checks without professional tools.
• Adjustable mounting brackets fit various roller shutter door frame structures.

Wiring Guide (Standardized Table)

Critical Warning

• Do NOT connect NO/NC terminals to the power supply positive terminal—this will damage the optical relay.

Blanking Mode Activation Steps

1. Power on the sensor grid and confirm correct wiring.
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)

• Industrial roller shutter doors (factories, warehouses, logistics centers)
• Commercial roller shutter doors (retail stores, shopping malls, commercial buildings)
• Cold storage roller shutter doors (refrigerated warehouses, freezer rooms)
• Garage roller shutter doors (residential, commercial parking facilities)

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 emitter/receiver lenses with a dry, soft cloth to remove dust, dirt, or condensation.
• Do not bend, twist, or pull cables forcefully; avoid scratching infrared lenses.
• Prevent direct sunlight or other infrared light sources from shining on the receiver (avoids false triggers).
• Ensure the roller shutter door or obstruction used for Blanking Mode meets the minimum continuous blocking distance requirement.
