Optical Sensors Photointerrupters Slot Type Logic Output: HOA6973-T55 application field and working principleOptical sensors are widely used in electronics, aviation, automotive, industrial automation and other fields, which are mainly used for controlling and sensing of physical parameters. Photointerrupters occupy an important position in the application of optical sensing, and they are widely used in instructions switch, counting, or detection of parts moving speed.HOA6973-T55 is a kind of slot type photosensor produced by HBOT. Slot type photointerrupter is mainly used for gap sensing, breaking detection, distance and speed detection, etc. HOA6973-T55 is able to operate at a wide operating temperature range, enabling it for high reliability and longer life.This device has several components in its working. It has an infrared LED light source, a photosensitive silicon detector which transfers light to electric signal, a source body protecting the light source, and a blacken chamber to prevent external light interference. The whole device is shaped like a rectangle or tube, with two long faces parallel to each other. The infrared LED emits light in both directions, which are reflected by the walls of the blacken chamber and collected by the photosensitive silicon detector. When nothing interrupts the light path, the detector can receive the light and the output will be “H” logic level. When an object interrupts the light path in between, the output will be “L” logic level.In addition, the HOA6973-T55 also has several features. Firstly, its directivity is very low, and it can collect reflected light up to 80%. Secondly, its signal output is very quick with a response time of 7.2 μs, making it suitable for high speed applications. Thirdly, it has compact design, dimension 8 × 8 × 8 mm and small package height and length. Fourthly, it is equipped with a shielding body that resists to environment interference. And lastly, it is compatible with IP65 protection and is rust-proof.HOA6973-T55 can be widely used in many fields, such as aviation, automotive, general security, industrial control, traffic management, and so on. It is capable of detecting movable objects, infrared rays, optical fibers, or even human body. It can be used in automatic assembly lines, conveyor systems, counting systems, automatic sensors, and so on. It can be applied to detect position and movement, gap sensing, breaking detection, distance and speed measurement, and other applications in its working area.Therefore, slot type photosensor such as HOA6973-T55 can provide targeting, trigger, distance and other functions, It can be widely used in many fields and provides fast, accurate and reliable signal output for various tasks.
