THROUGH BEAM SENSOR WITH AMPLIFIER UNIT
Download our Brochure For Technical Details
WORKING PRINCIPLE
This consist of two devices; a light emitter and a light receiver. These two devices are kept apart facing each other. The Gallium-Aluminium-Arsenide-Luminescent diode integrated in the transmitter sends pulses of light in the infra-red range which are invisible to the human eye. The receiver opposite to the transmitter receive these rays. Sensing is achieved when these rays are interrupted by the object.
ADVANTAGES
– Large sensing distance is possible as emitter and receiver are kept opposite to each other.
– Suitable for precise detection of large as well as small objects.
– Repeatability and indexing precision are not impaired even if the object surface or background is reflecting.
FIELD OF APPLICATION
Through Beam Sensors are used for sensing semitransparent opaque objects such as Glass/Plastic Bottle, Sliver breakage detection, Paper breakage detection, Door opening/closing etc.
