Industrial Gate Safety Light Curtain Sensor with No/Nc Output and 4 Beams 1m Long
Working principle:
Infrared beam sensors operate based on the principles of infrared radiation emission, reflection, and reception. The fundamental working principles are outlined as follows:
-
Infrared Emission: The sensor incorporates an infrared emitter that projects an infrared beam.
-
Beam Propagation: The emitted infrared beam travels along a defined path, creating a virtual beam.
-
Target Interaction: If there is a target object along the beam path, it interacts with the infrared light. The target's reflection, absorption, or scattering of the infrared light causes variations.
-
Reflection or Scattering: The sensor includes an infrared receiver designed to capture the reflected or scattered infrared light returning from the target.
-
Signal Processing: The received signal undergoes processing, analyzing features such as signal strength, frequency, or other characteristics to determine the presence, distance, or other relevant information about the target.
-
Output Results: The analyzed results are typically output as electrical or digital signals, triggering corresponding actions, alarms, or data recording.
The ultimate solution for industrial door protection, barrier gate safety, and home security. Our standard model stands at 1 meter tall and is equipped with 4 infrared beams, delivering unmatched functionality and dependability.
