Overview
The Blanking Light Curtain - CL15-8L8 by Shenzhen Jutai Comm Co., Ltd. is an advanced safety device designed to enhance the security and efficiency of industrial doors. It features a robust active infrared sensor with exceptional light resistance, ensuring reliable performance in various lighting conditions. With an impressive detection range of up to 8 meters and a rapid response time, this sensor is vital for safety monitoring in diverse industrial applications, making it a valuable asset for workplace safety.
Working Principle and Application
- Principle: It usually consists of an emitter and a receiver to form a light curtain system. The emitter emits a series of parallel infrared beams, and the receiver receives these beams. When the light curtain is blocked by an object, the receiver detects the change in the light signal.
- For preventing industrial doors from crushing: In industrial door scenarios (such as large rolling doors in factories, garage doors, etc.), if an object (such as personnel, vehicles, goods, etc.) enters the area below the door during its descent or closing process, the light curtain sensor can quickly detect it and send a signal to the control system to stop the door from closing or reverse its opening, thus preventing the door from crushing the object and causing damage or safety accidents.
Blanking Function (This is its distinctive feature)
- The blanking function works in such a way that if the beams are blocked sequentially from top to bottom, this will not trigger the relay and is considered a normal door closing. However, if the beams at the bottom of the door are blocked during the closing process, the relay signal will be output.
- Improves production efficiency and flexibility: Without sacrificing safety, situations that would otherwise trigger unnecessary shutdowns can be avoided, allowing industrial processes to proceed more smoothly.
Key Takeaway
A blanking light curtain is a specialized safety apparatus that allows specific sections of its detection field to be deactivated, or "blanked," without affecting the entire curtain. This feature is essential in environments where machinery or production processes regularly interrupt the light curtain's field. By selectively blanking these areas, the light curtain maintains protection by detecting unexpected interruptions in non-blanked sections, ensuring safety without unnecessary stoppages or false alarms. This functionality is particularly beneficial in complex automated environments where both flexibility and safety are crucial.
