ET4-E3228 Datasheet/PDFET4-E3228 Photoelectric Sensors are electronic devices, widely used in industrial applications, to detect and measure the distance, presence, or absence of various objects. This sensor has a high-speed response and superior accuracy & stability, is perfectly suitable for applications demanding high data readout accuracy. It is one of the more popular types of optical sensors used in various industrial settings.
Application Field and Working Principle
ET4-E3228 Photoelectric Sensors are used in a wide range of industrial applications, including factory automation, material handling, and non-contact indoor and outdoor detection. For instance, they can be used for identifying and tracking products during production, monitoring the level of liquids or granular material in vessels, and indication of the approach or the distance between two points. They can also be used for presence or absence of objects in flow processes and measurement of distances in material testing.
The basic principle of this type of sensor is a radiation emission combined with radiation absorption in an integrated circuit. The device emits a signal from an optical fiber that is then received by a receiver to measure the distance or presence of an object. This signal is then processed by the integrated circuit and the distance is then calculated in real time. As a result, the sensor can accurately measure the distance or presence of an object without contact.
By combining different emitters and receivers in a single device, more complex applications can be achieved, such as an optical line with 3D measurement capabilities. Such technologies enable flexible solutions for virtually any industrial application. Moreover, features such as environmental protection, electromagnet interference (EMI) immunity, safety, and automation, make this sensor really useful for industrial applications.
The ET4-E3228 Photoelectric Sensor also uses infrared (IR) light, which gives it a special advantage because IR light is nearly invisible to the human eye and therefore it can be used for applications that require a hidden detection system. The device\'s detection range is from 10 cm to 30 m, making it suitable for applications such as presence or absence detection of objects in flow processes, distance measurement between objects, and level and flow control.
Conclusion
The ET4-E3228 Photoelectric Sensor is a reliable and versatile optical sensing device, suitable for a wide range of industrial applications. It has a high-speed response and superior accuracy & stability, making it ideal for applications demanding high data readout accuracy. Moreover, it uses invisible IR light for detection, which gives it a special advantage in applications requiring unknown detections. Finally, its detection range is wide enough to make it suitable for many different applications.
