RPR-220

The RPR-220 is an optical reflective sensor that is capable of detecting the presence of objects. It is equipped with an analog output, which makes it suitable for a wide range of applications. This article will discuss the application field and working principle of the RPR-220.

Application field

The RPR-220 is most often used in industrial automation applications, such as conveyor belt monitoring, part presence monitoring, level detection, robot pick-and-place, PLC input/output monitoring, and many others. It is designed to handle a wide variety of environments, with a working temperature range of -10℃ to +75℃. It is also resistant to dust, oil and water.

The RPR-220 has adjustable sensitivity, which makes it suitable for detecting objects of various shapes, sizes, and materials. It can accurately detect objects that are positioned up to 80mm away from the sensor.

Working Principle

The RPR-220 consists of an infrared LED, a phototransistor, and an adjustable potentiometer. When a reflective object is detected, the infrared light emitted by the LED is reflected back to the phototransistor, causing a voltage change. The signal from the phototransistor is sent to the potentiometer, which adjusts the voltage to a usable range. The analog output then sends the signal to a controller, which interprets the data based on its configuration.

The RPR-220 is easy to configure, with only a few settings needed. It has an adjustable time-delay setting and a variable time-delay setting, which allows for quick sensor alignment and installation.

Conclusion

The RPR-220 is an optical reflective sensor that is designed for industrial automation applications. It is equipped with an analog output, which makes it suitable for a wide range of applications. Its adjustable sensitivity and easy configuration make it easy to use, while its resistance to dust, oil, and water ensures reliable performance in harsh environments.
