Safety Anti Pinch Photocell with 1m 4 Infared Light Beams for Industrial PVC Fast Door
Product Name: JUTAI Safety Light Curtain Sensor
Product Description: The JUTAI Safety Light Curtain Sensor is a state-of-the-art solution designed to ensure the safety and security of industrial doors, barrier gates, and residential areas. Standing at 1 meter tall and equipped with 4 infrared beams, this sensor offers unparalleled functionality and reliability. Engineered to endure harsh environments and intense light interference, it provides robust protection with an IP65 waterproof rating.
Working Principle: The operation of the JUTAI Safety Light Curtain Sensor revolves around the emission, propagation, interaction, reflection, and reception of infrared radiation. Here’s a detailed look at its working principles:
Infrared Emission:
- The sensor emits an infrared beam using a built-in infrared emitter.
Beam Propagation:
- This infrared beam travels along a predefined path, creating an invisible detection barrier.
Target Interaction:
- When an object intersects the beam, it interacts with the infrared light by reflecting, absorbing, or scattering it.
Reflection or Scattering:
- The sensor’s infrared receiver captures the reflected or scattered infrared light from the object.
Signal Processing:
- The sensor processes the received signal to analyze attributes such as signal strength and frequency, determining crucial details about the object, like its presence and distance.
Output Results:
- The processed data is then converted into electrical or digital signals, which can trigger actions, alarms, or data logging.
Key Features:
-
Exceptional Durability:
- Designed to resist severe light interference and tough outdoor conditions, the sensor features an IP65 waterproof rating, ensuring long-lasting durability.
-
Extended Detection Range:
