Optical sensors are very important in electrical and electronic engineering because they allow us to detect changes in the environment. In particular, they can be used to detect the presence of objects such as people or vehicles. Photointerrupters are a type of optical sensor used for this purpose. In this article, we will take a look at the OPB972N55 photointerrupter, which is a type of slot type photointerrupter with logic output.

The OPB972N55 photointerrupter consists of three main parts: an LED, an optical slot, and an output transistor. At the heart of the device is the LED element, which emits an infrared light. The light is directed into a small slot cut into the device’s housing. When an object passes through the slot, the light is momentarily broken and the output transistor switches.

The OPB972N55 photointerrupter has several applications. It can be used for security systems, in place of traditional mechanical switches, or in proximity sensing. It can also be used in robotics for navigation, obstacle avoidance, and velocity control. In all of these applications, the OPB972N55 can provide a reliable output signal when an object passes through the optical slot.

The device is easy to install and is powered by a single 5V supply. It has a fast switching speed, a wide operating temperature range, and is available in a variety of mounting choices. It can also be used in conjunction with other sensors such as infrared, ultrasonic, and micro switches, allowing it to provide an even more comprehensive sensing solution.

The OPB972N55 photointerrupter has an open collector logic output. This type of output is commonly used in digital logic circuits and is designed to provide a high output signal when an object passes through the slot, and a low signal when no object is present. The output signal can be used to trigger an external control circuit such as an alarm or a timer.

The device is also relatively low cost and available in a wide range of packages, allowing it to be used in both commercial and hobby applications. It is also rated for up to 10 million cycles, making it suitable for long-term applications. In addition, it has built-in EMC compliance, which ensures that it does not produce any noise that could interfere with nearby circuits.

In summary, the OPB972N55 is a type of slot type photointerrupter with Logic output that is capable of providing reliable switching and sensing solutions, including security systems, proximity sensing, and robotics. It is easy to install, has fast switching speed, and is highly durable. With its wide range of features and applications, the OPB972N55 is an excellent and cost-effective solution for any project.
