Industrial DoorBlanking Safety Light Curtain, Aluminum Alloy Shell, Suitable for Rolling & Rapid Door Safety
Engineered specifically for rolling and rapid door safety, this Industrial Door Blanking Safety Light Curtain features a premium aluminum alloy shell that delivers exceptional durability—resisting impact, corrosion, and daily wear from industrial debris or frequent door operation. This robust housing not only extends the device’s lifespan but also ensures stable performance in high-use environments like warehouses, manufacturing plants, or logistics hubs where rolling and rapid doors operate continuously. Equipped with an IP67 protection rating, it stands up to dust accumulation and occasional water splashes, while its wide operating temperature range of -20℃~+60℃ eliminates concerns about malfunctions in cold storage facilities or hot production workshops. The core blanking function is tailored for rolling and rapid doors: it intelligently ignores beam blockages caused by the door’s own downward movement, preventing false triggers, while instantly detecting foreign obstacles (people or goods) to halt or reverse the door, effectively avoiding pinch injuries.
As a reliable safety solution for rolling and rapid doors, this Blanking Safety Light Curtain’s aluminum alloy shell offers both structural strength and practicality—its lightweight design simplifies installation in tight spaces, such as door gaps or tracks, without requiring complex mounting adjustments. The device is fitted with 8 high-precision infrared eyes and a stable detection range of 1-8m, ensuring full coverage of the rolling/rapid door’s operating area to catch even small obstacles that could lead to accidents. Clear LED status indicators enhance usability: a red light signals beam blockage by obstacles, a steady blue light confirms normal operation, and a blinking blue light alerts to misalignment between the transmitter and receiver—allowing maintenance teams to troubleshoot quickly and minimize downtime. With a working voltage of DC12V-24V, it seamlessly integrates with most industrial power systems, and its low power consumption (receiver <20mA@DC12V) reduces energy costs while providing uninterrupted anti-pinch protection for rolling and rapid doors
1. Core Structural & Performance Advantages
The product’s design and performance are optimized for harsh industrial environments, ensuring long-term stability and safety:
Durable & Protective Housing: Adopts a high-strength aluminum alloy housing combined with fully encapsulated internal components. This structure not only resists impact, corrosion, and mechanical wear but also achieves an IP67 protection rating—effectively preventing dust intrusion and damage from short-term water immersion, making it suitable for workshops with oil fumes, dust, or frequent cleaning.
Fast Response & Stable Detection: Equipped with a high-sensitivity signal processing chip, the response time is as fast as ≤20ms, ensuring immediate triggering of safety measures (e.g., door reversal or stop) when an obstacle is detected. Its stable detection range covers up to 8 meters, fully meeting the width requirements of most standard and large industrial doors.
Safety-Oriented Output Design: Features a default normally closed (NC) relay output—a safety-focused configuration that ensures the door stops or reverses immediately if the light curtain loses power or is interrupted, avoiding potential risks caused by power failures.
2. Installation Flexibility & Blanking Function
The product solves common pain points in industrial door safety device installation and operation:
Compact & Space-Saving Design: With a slim profile, it can be directly installed in narrow gaps between industrial door frames and tracks, or mounted on the side of door guide rails. No major modifications to the existing door structure are required, reducing installation time and costs.
Intelligent Blanking Function: The unique Blanking Function is the core advantage of this series. It can be pre-set to "ignore" fixed obstructions (such as door hinges, reinforcing ribs, or fixed brackets) within the detection area. This ensures the light curtain only triggers an alarm or stops the door when encountering moving objects (e.g., personnel, forklifts, or goods), completely avoiding interference with the door’s normal downward closing process.
Strong Anti-Light Interference: Uses high-quality infrared LEDs with narrow-band filtering technology, which can resist interference from strong ambient light (such as direct sunlight, high-brightness workshop lamps, or strobe lights). It maintains stable detection performance in both indoor and semi-outdoor industrial environments.
Diversified Specification Selection: To match different industrial door heights and safety requirements, the series offers four length options: 1m, 1.5m, 2m, and 2.5m. Each length is further divided into two beam configurations—8-beam and 16-beam:
8-beam version: Suitable for scenarios with low to medium safety requirements (e.g., non-personnel-intensive storage area doors), balancing cost and basic protection.
16-beam version: Features higher detection density (smaller beam spacing), suitable for high-risk areas (e.g., workshop doors with frequent personnel and forklift movement) to ensure no small obstacles or body parts are missed.
Transparent Pricing Logic: The number of beams is the primary factor affecting the price—since more beams require more infrared emitters/receivers and more precise calibration. You can select the most cost-effective combination based on your industrial door’s height (matching the light curtain length) and on-site safety level (matching the beam count).
Whether you need to upgrade the safety system of existing industrial doors or equip new doors with reliable protection, this Blanking Safety Light Curtain series provides a "customizable, easy-to-install, and highly reliable" solution to safeguard personnel and property in industrial sites.
