Multibeam Infrared Sensor for Sectional Doors | 1-8m Range, 20ms Response, Aluminum Housing

Paragraph 1: Introducing the Multibeam Infrared Sensor (Focus on Performance and Key Specs)

Upgrade the safety profile of your sectional and high-speed industrial doors with our high-performance Multibeam Infrared Sensor series. Engineered for rapid, reliable object detection, this safety light curtain features a blistering 20ms Fast Response time, ensuring immediate signal output to halt the door upon sensing an obstruction. The robust sensor is designed to cover detection lengths up to 2.5m with a stable operating range of up to 8 meters between transmitter and receiver. By utilizing multiple high-quality infrared beams (available in 8 or 16 beams), it creates an impenetrable safety barrier across the entire closing path. This device is the perfect, seamless integration solution for new or existing industrial doors requiring superior, continuous area monitoring to prevent costly damages and safeguard personnel.

Paragraph 2: Durability, Environmental Resistance, and Cost-Efficiency

Our Multibeam Infrared Sensor is built to withstand the harshest industrial conditions. Encased in a durable Aluminum Housing and featuring a Full-Potting Design with thermal conductive adhesive, it achieves an industry-leading IP67 waterproof rating, making it suitable for cold storage, humid, and condensation-prone environments (operating reliably from -30 degrees Celsius to 70 degrees Celsius). The system incorporates advanced Anti-Interference technology, effectively resisting electromagnetic, UV, and intense light sources. Optimize your installation and maintenance budget with the sensor's inherent Cost-Effective design: it uses a single-pair installation method and a Cable-Free synchronization system. Choose from standard lengths (1m, 1.5m, 2m, 2.5m) with variable beam counts to find the perfect safety solution for your specific Sectional Doors, ensuring long-term reliability and minimal operational cost.

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.
