Anti-Pinch Safety Barrier for Overhead Doors | Blanking Function, 8/16 Beam Options

Paragraph 1: Introducing the Blanking Safety Light Curtain (Focus on Safety and Technology)

Ensure maximum safety and operational efficiency for your facility's industrial doors with our Blanking Safety Light Curtain Series. Specifically engineered as a reliable Anti-Pinch Safety Barrier for high-speed, overhead sectional, and cold storage doors, this device prevents accidents by instantly detecting obstructions in the door's closing path. The core of its advanced performance is the proprietary Blanking Function, a smart technology that ignores the door's normal closing structure (such as cables or seals) while remaining highly sensitive to foreign objects. This intelligent discrimination ensures the light curtain will not interfere with the door's regular downward motion, eliminating nuisance trips and downtime. Featuring a rapid 20ms response time and rugged, anti-interference components, our light curtain provides dependable protection in the most challenging industrial environments, offering true peace of mind.

Paragraph 2: Key Features, Specifications, and Installation Advantages (Focus on Durability and Cost)

Our Blanking Light Curtain is built for extreme durability and cost-effectiveness. The unit boasts an IP67 waterproof rating due to a robust aluminum housing with a full-potting thermal conductive adhesive, making it ideal for cold storage and washdown areas. We offer flexibility to meet any installation requirement, with lengths available up to 2.5m and two beam density options: 8-beam for standard protection or 16-beam for high-security applications. Installation is significantly simplified by a Cable-Free Design, which requires no synchronization wire between the transmitter and receiver, drastically cutting labor and wiring costs. Furthermore, its single-pair configuration delivers the safety of conventional dual-pair systems with a single, highly adaptive 12-24VDC power supply, resulting in a superior, low-maintenance, and cost-efficient safety solution.

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.

3. Environmental Adaptability & Specification Options

• 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.
