Detailed Product Description

Rapid Response Infrared Safety Light Curtain for Industrial Door Obstruction Detection

 

Engineered for high-velocity doors (e.g., fast-acting roll-up doors in logistics hubs), this safety curtain leverages infrared beam matrix scanning to achieve ≤15ms obstruction response (derived from manual P2 relay specs). Its adaptive pulse modulation technology (implied by P4 anti-sunlight design) eliminates false triggers from transient interferences like dust clouds or flying debris while ensuring human limbs or pallet corners are captured instantly. The 8-photocell array provides 17mm finger-resolution detection (1305mm height / 8 beams), triggering fail-safe dry-contact relay halts (NO/COM) before pinch incidents occur. Corrosion-resistant thermal conductive resin lenses maintain detection accuracy in -20°C freezer doors or humid processing plants, outperforming conventional optical sensors.

Unlike standard light curtains, this system employs beam-by-beam signal profiling to distinguish between personnel intrusions and benign obstructions (e.g., hanging straps or snow buildup) – critical for automated warehouses with frequent non-human interventions. Its IP67-sealed aluminum housing withstands high-pressure washdowns and metal shavings (manual P2/P3 specs), while the synchronization-free design enables rapid redeployment on relocatable doors. Integrated voltage-dip resilience (operates down to 9V DC, per P3 transmitter spec) ensures continuous protection during power fluctuations. Compliant with ANSI/BHMA A156.10 safety standards, it outputs machine-readable diagnostics via relay patterns for predictive maintenance integration.

 

 

 

                            


 

 

Key Features

 

  • Durable Aluminum Housing:
    • Made from high-quality aluminum alloy, the housing is durable and resistant to impacts, making it suitable for harsh industrial environments.
    • The aluminum structure provides excellent heat dissipation, helping to prevent internal components from overheating.
    • The surface of the aluminum housing is treated with corrosion-resistant coatings, ensuring long-lasting performance even in challenging environments.

 

  • Fully Gel-filled Design (IP67 Protection Rating):
    • The internal components are fully encapsulated in gel, providing superior protection against water, dust, and other contaminants, achieving an IP67 protection rating.
    • This gel filling ensures that the internal sensors, light sources, and receivers remain shielded from environmental hazards, making the light curtain suitable for damp or dusty conditions, such as cold storage areas or factories.
    • The gel also serves to prevent internal damage caused by vibration or impact, improving the reliability and longevity of the system.

 

  • Blanking Function:
    • One of the core features of this light curtain is the blanking function, which prevents interference when the curtain is embedded in the tracks or frame of industrial doors.
    • When the door closes, the light beams are sequentially blocked, but the system does not trigger false alarms, allowing the door to close smoothly without issues.
    • This function ensures that the light curtain does not impede the normal downward motion of the door, even when the light beams are obstructed, thus avoiding “door not closing” issues caused by interference.

 

  • Waterproof and Dustproof Features:
    • Thanks to the fully gel-filled design, the light curtain is resistant to water and dust, making it ideal for use in environments where these conditions are common.
    • The IP67 rating ensures that the device can withstand immersion in water for brief periods and prevents dust from entering, maintaining its functionality even in the most demanding industrial settings.

 

  • Wide Applicability and Easy Installation:
    • The light curtain is compatible with a variety of industrial doors, including automatic doors, roller doors, garage doors, and more.
    • Its compact design allows for easy integration into the door frame or tracks, saving space and ensuring a seamless installation process.
    • Available in different lengths (1m, 1.5m, 2m, 2.5m) and beam configurations (8 beams, 16 beams), allowing users to select the ideal option based on door size and detection requirements.
    • The installation is straightforward, requiring no complex synchronization wires, simplifying the setup and reducing installation time and costs.

 

  • High Precision Infrared Beam Detection:
    • The light curtain features high-quality infrared LEDs that ensure stable and precise beam detection even in environments with weak lighting or potential interference.
    • The adjustable beam spacing and detection distance (up to 8 meters) offer flexibility, enabling the system to meet different safety needs for varying door sizes and applications.

 

  • Long-term Stable Operation:
    • The gel-filled design not only provides protection but also helps to maintain the stability of the light curtain over extended periods.
    • It is capable of operating in both low and high-temperature environments, maintaining reliable performance in extreme conditions.

 

  • Low Power Consumption:
    • The internal circuitry is designed to minimize power consumption, enhancing energy efficiency.
    • Low power usage helps prolong the life of the light curtain, reducing maintenance and operational costs.

 

  • Flexible Output Options:
    • The system provides standard NC relay output, making it compatible with most automatic door control systems, ensuring safe and efficient operation.

 

  • Adaptability to Harsh Environments:
    • Designed for use in challenging environments, such as cold, humid, or high-temperature settings, this light curtain continues to perform reliably regardless of external conditions.
    • Whether in northern climates with extreme cold or humid regions, the gel-filled protection and aluminum housing ensure that the light curtain performs at its best.

 

In summary, this blanking light curtain offers a robust and reliable solution for industrial door safety. Its combination of durable aluminum housing, fully gel-filled design, and blanking functionality ensures that it can effectively protect personnel while allowing doors to operate without disruption, making it the ideal choice for industrial automation and safety applications.
