Optical Sensors are used for detecting the presence of objects in a specific area. The output can be a digital signal or an analog signal depending on the specific application.A Photointerrupter is a type of optical sensor which uses light to detect the presence of an object. It consists of a light source and two photodetectors, which are placed in a slot so that the light source and one of the photodetectors will be blocked when an object is placed between them.The H21B5 is a transistor output Slot Type Photointerrupter which is designed for use in a range of applications. It operates on a supply voltage of 5V and has a maximum current of 200mA. The output signal is a logic gate level, which can be used to detect the presence of objects. The detector has a viewing angle of 120° and a switching frequency of up to 10kHz. It is also IP67 rated, making it suitable for use in harsh environments.

The working principle of the H21B5 is quite simple. When an object is placed between the light source and one of the photodetectors, it will block the light and the output signal will be low. When the object is removed, the light will be allowed to pass through again and the output signal will go high. This signal can then be used to control any number of devices, such as relays or motors, depending on the application.

The H21B5 is a versatile, lightweight and cost-effective solution for detecting the presence of objects in many different applications. It is suitable for use in industrial control systems, robotics, automotive and aviation applications, safety systems and more.The H21B5\'s compact size and high switching frequency make it ideal for applications where space and speed are of paramount importance. The device is easy to integrate and its low cost makes it an attractive option for cost-sensitive applications.

The H21B5 provides a reliable and cost-effective way to detect the presence of objects in a wide range of applications. The device is compact and lightweight, and its IP67 rating ensures that it can be used in even the harshest environments. The simple working principle and the logic gate level output makes it easy to integrate in any system, and its switching frequency of up to 10kHz makes it suitable for a wide range of applications. All these factors make the H21B5 an ideal choice for any application where the presence of an object needs to be detected.
