Optical sensors are electronic devices that utilize light for sensing and control purposes. Photointerrupters are a type of optical sensor that detect motion and other interruptions in the incident light. The OPB390L51 is a slot type photointerrupter with a transistor output that can be used for a variety of applications.

One of the most important features of the OPB390L51 is its automatic light intensity adjustment. This makes it ideal for applications that require precise and accurate sensing. The OPB390L51 also boasts an excellent response time, breaking the light beam within 5 microseconds. This makes it perfect for high speed applications that require quick sensing and control.

The working principle of the OPB390L51 is relatively straightforward. The sensor is composed of two parts: an emitter and a receptor. The emitter sends out a beam of light which is then detected by the receptor when it is interrupted. When the light beam is interrupted, the output voltage of the sensor changes. This change in voltage can then be used to control a variety of devices and actuators.

The OPB390L51 is very versatile and can be used in a variety of applications. It is perfect for industrial control, motion sensing, and safety applications. It can be used to detect interruptions in conveyor belts, detect the presence of a person or object in a restricted area, and to detect motions in machinery.

Overall, the OPB390L51 is an excellent choice for applications that require precise and accurate sensing. It is highly versatile and can be used in a variety of applications. It is also very easy to use and highly reliable. With its excellent response time and automatic light intensity adjustment, this sensor is an excellent choice for applications that require quick sensing and control.
