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.
– 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.
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.
