The SH-72 photointerrupters incorporate a slot type logic optical output, in which a light source and a photodetector are encased in a plastic package. The integrated mechanism utilizes a small slot for the light to pass through an object, and then the photodetector is triggered upon reaching the small obstruction. Such photointerrupters are widely used for developing a wide range of applications, such as material handling, safety systems and detection systems for transportation.

This type of photointerrupter is ideal for feature recognition applications involving detection of small objects, as well as the speed and position monitoring of large objects. Users can insert block-shaped objects in the small slot to determine the timing of when the light passes through, thereby creating a pulse-like wave that can be accurately and reliably detected. The SH-72 is also used for other types of applications, such as counting items, detecting the presence of a material, and communication.

The SH-72 can also be effectively used in medical environments. For instance, it can be used in X-ray film scanners, which use the light of the photointerrupter to detect the opacity of the X-ray film. This technology is also used in cardiology departments to monitor the presence of diabetes in patients. Furthermore, it can be used in the laboratory for lab analysis, in order to count the number of cells in a sample, or to measure the speed of a chemical reaction, or even to monitor the accuracy of a surgery.

Moreover, the SH-72 is an excellent choice for a wide range of industrial operations. Its small size, fast response time, high reliability, and low power consumption make it ideal for industrial machines, robots, and other systems at an industrial scale. For instance, it can be used to count pieces in a manufacturing line and conveyor systems or to measure the speed of a motor. Additionally, the photointerrupter can be used for controlling the movement of moving parts, such as slides or racks, and can be used to identify blockages in production lines.

The working principle of a SH-72 photointerrupter involves the use of an infrared light emitting diode (LED) and a phototransistor. The IR LED emits infrared light onto the phototransistor, which in turn triggers a logic output when the light is blocked. This logic output is used to detect the presence or the absence of an object at various distances from the photointerrupter. The range of the soundless output can be adjusted by changing the intensity of the applied voltage.

The SH-72 photointerrupter is an advantageous optical detection device that offers great accuracy, sensitivity, and stability. Its power consumption is also very low, making it suitable for a long list of applications. When compared to other forms of detection devices, the SH-72 is more stable, reliable, and efficient, and offers an improved resolution for a wide variety of detection tasks.
