DC 12-24 V IP 67 Blanking Light Curtain Photoelectric Protection Device Cold Storage Doors No Synchronization Line
The DC 12-24 V Blanking Light Curtain Photoelectric Protection Device is a vital safety solution designed specifically for cold storage doors, ensuring the protection of personnel and goods in temperature-sensitive environments. This innovative light curtain features a no synchronization line design, simplifying installation and reducing maintenance requirements while maintaining high safety standards. Ideal for use in refrigerated warehouses and food processing facilities, it helps prevent accidents during door operations.
Utilizing advanced photoelectric technology, this blanking light curtain creates an invisible safety barrier that accurately detects the presence of individuals and objects. The blanking feature allows the system to ignore certain items, such as pallets or carts, while still monitoring for human presence, enhancing safety without hindering workflow. Operating within a DC 12-24 V power range, it is compatible with various automated door systems. The quick response time ensures that any interruption in the detection beams triggers immediate safety protocols, such as stopping or reversing the door’s movement. By integrating the DC 12-24 V Blanking Light Curtain into cold storage door systems, businesses can significantly enhance operational safety, streamline access control, and create a secure environment that protects both employees and perishable goods.

Key features

Application
Application |
Roller shutter doors | Sliding doors |
Folding doors | High Speed Doors |
Cold storage doors | Fire Doors |
- 1. Roller shutter doors:
- Installed on both sides of the rolling door to prevent the door from colliding with any object or person during closing.
- Advantages: Increased safety, reduced damage and repair costs due to accidental collisions.
- 2. Sliding doors:
- Used in sliding door systems to detect any obstacles in front of the door and ensure that the door does not cause injury to personnel or equipment as it moves.
- Advantages: Improves operational efficiency and ensures the safe passage of people and goods.
- 3. Folding doors:
- Installed on or near the edge of a folding door, detects in real time any object within the door's path of movement.
- Advantage: Provides reliable protection against injuries caused by the door during folding and unfolding.
- 4. High Speed Doors:
- High speed doors are typically used in environments that require frequent opening and closing, such as workshops and warehouses. The privacy grating responds quickly to detect obstacles in front of the door.
- Benefits: Ensures efficient operation while preventing injury from fast moving doors.
- 5. Cold storage doors:
- Cold storage doors need to be opened and closed frequently to maintain temperature. An anti-infiltration grating prevents the door from colliding with personnel or handling equipment while closing.
- Advantage: Protects personnel while avoiding damage to equipment and the door.
- 6. Fire Doors:
- In an emergency, fire doors need to close quickly. The fire barrier ensures that there are no obstacles in the way of the emergency closing process, ensuring safety and smoothness.
- Advantage: Provides safety at critical times and ensures that evacuation routes are clear.

Conclusion
Blanking gratings in a variety of industrial door applications significantly improve safety and operational efficiency by providing real-time detection and response. Their use not only protects people and equipment, but also reduces maintenance and downtime due to accidental collisions and damage, thereby increasing overall productivity and safety levels.
