lanking Light Curtain, IP67 Protection Level, Aluminum Alloy Housing, -20℃~+60℃ Operating Temperature

1. Designed specifically for industrial door safety, this Blanking Light Curtain stands out with its robust IP67 protection level—offering complete dustproof and waterproof performance that makes it ideal for harsh industrial environments like workshops, warehouses, and cold storage facilities. Crafted with a durable aluminum alloy housing, it resists impact, corrosion, and daily wear, ensuring long-term reliability even in high-frequency use scenarios. What’s more, its wide operating temperature range of -20℃~+60℃ eliminates concerns about performance issues in extreme cold or hot conditions, whether installed outdoors or in temperature-fluctuating indoor spaces. Equipped with 8 infrared eyes and a stable detection range of 1-8m, it accurately identifies obstacles (people or objects) near industrial doors (such as rapid doors, rolling doors, and elevating equipment), triggering safety measures instantly to prevent pinch injuries while using the blanking function to avoid false triggers from the door’s own movement

2. This Blanking Light Curtain is a critical safety component for industrial automation systems, combining ruggedness and precision to enhance industrial door operation safety. Its IP67 rating ensures it can withstand splashes, dust accumulation, and even short-term exposure to wet conditions, while the aluminum alloy housing adds structural strength to handle the rigors of industrial settings. The -20℃~+60℃ operating temperature adaptability means it works seamlessly in cold storage facilities (where low temperatures are common) and high-temperature production workshops alike, without compromising detection accuracy. It features clear LED status indicators—red for obstacle blockage, blue for normal operation, and blinking blue for misalignment between the transmitter and receiver—allowing for quick status checks and troubleshooting. With a working voltage of DC12V-24V, low power consumption (less than 20mA for the receiver at DC12V), and switchable NO/NC output (default NO), it easily integrates with most industrial door control systems, providing consistent anti-pinch protection and ensuring smooth, safe door operation.

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.
