ET4-N3215 Application Field and Working Principle

ET4-N3215 is a type of optical sensor in the category of Photoelectric, Industrial. It is designed to detect proximity of objects and displays output in the form of a lot of digital signals as well as analog signals. It operates from a symmetrical power supply in the range of +8 V to +24 V DC. The device utilizes a tri-color light emitting diode, capable of red, yellow, and green light emission. The LED light source is modulated to generate the desired color, and also used for sensing objects. Additionally, a photo cell is used for receiving the reflected signals, and these two components serve as the input stage in the sensing system.The device consists of two main components – the LED light source and the photo cell. The LED light source performs the dual functions of light emission and detection. The photo cell detects and measures changes in light intensity to produce output signals. The ET4-N3215 can be used for both sensing and counting, providing reliable precision measurements for a multitude of different applications. It is ideal for detecting objects at distances of up to 8 meters, making it suitable for use in high throughput operations such as counting objects on conveyor belts and automated production lines.In terms of working principle, the ET4-N3215 uses a pulsed LED light source, combined with a photo cell, to detect the presence of an object. When an object is detected, the LED light intensity is modulated, and the photo detector detects the change in intensity. The output signals are then fed into dedicated electronic circuits, where they are processed to generate a variety of signals. These signals can include a status signal indicating an object is present, how far the object is from the sensor, and the speed at which the object is moving.The ET4-N3215 is extremely versatile and is suitable for a broad range of industrial applications. It is capable of detecting objects in harsh environmental conditions, and is extremely durable, due to its robust metal housing. The device has a wide range of analog and digital output signals, which allow it to be integrated easily into existing control systems. In addition, the device features an adjustable sensing range, allowing it to be tailored to meet the specific requirements of a given application. Overall, the ET4-N3215 is an ideal choice for a variety of industrial applications. Thanks to its advanced features, such as its adjustable sensing range and wide range of output signals, the ET4-N3215 is a highly reliable, cost-effective solution for a number of industrial sensing applications.
