Working Principle

Infrared beam sensors operate by emitting, propagating, and receiving infrared radiation to detect objects. Here's a detailed breakdown of their functionality:

Infrared Emission:
An infrared emitter generates a focused beam of infrared light.

Beam Propagation:
The emitted beam travels through a predetermined path, creating an invisible detection line.

Target Interaction:
When an object crosses this path, it interacts with the beam through reflection, absorption, or scattering of the infrared light.

Reflection or Scattering:
The infrared receiver within the sensor captures the reflected or scattered light from the object.

Signal Processing:
The sensor processes the received signal, analyzing parameters such as signal strength and frequency to determine the presence, distance, or other relevant characteristics of the object.

Output Results:
The analyzed data is converted into electrical or digital signals, which can then trigger specific actions, alarms, or data logging.
