Blanking Light Curtain, DC12V-24V Wide Voltage, Anti-Pinch Function for Industrial Automation Systems

Blanking Light Curtain, DC12V-24V Wide Voltage, Anti-Pinch Function for Industrial Automation Systems

1. As a critical safety component for industrial automation systems, this Blanking Light Curtain excels with its DC12V-24V wide voltage design, seamlessly adapting to various industrial power supply configurations without the need for additional transformers—simplifying integration into existing rapid door, rolling door, or elevating equipment control systems. Its core anti-pinch function works by creating a protective beam network between the transmitter and receiver: the moment a person or object enters the detection area, the blocked beams instantly trigger the safety system to halt or reverse the door’s movement, effectively preventing pinch injuries and equipment damage. With a stable detection range of 1-8m and 8 infrared eyes, it ensures comprehensive coverage of industrial door operation zones, while the blanking mode further eliminates false triggers caused by the door’s own downward motion—striking a perfect balance between safety and operational efficiency for industrial automation workflows.
2. Engineered to enhance safety in industrial automation systems, this Blanking Light Curtain leverages its DC12V-24V wide voltage compatibility to fit diverse industrial setups, from small workshops to large-scale manufacturing facilities. The anti-pinch function is not only reliable but also low-power: the receiver operates at less than 20mA@DC12V and the transmitter at less than 65mA@DC12V, reducing energy consumption while maintaining consistent performance. It features clear LED status indicators—red for beam blockage, blue for normal operation, and blinking blue for transmitter-receiver misalignment—allowing maintenance teams to quickly identify and resolve issues, minimizing downtime for industrial doors like rapid doors and rolling doors. Constructed with an aluminum alloy housing and an IP67 protection rating, it resists dust, water, and harsh industrial conditions, ensuring long-term durability while providing uninterrupted anti-pinch protection for industrial automation systems

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.
