Encoders: DP11SVN15B20S application field and working principle

An Encoder is an electromechanical device which is used to measure the angular displacement of a rotational object such as a wheel, shaft, motor shaft, or other machine parts. The DP11SVN15B20S Encoder has a proven accuracy of 0.05° angle resolution and can measure up to 360°. The shaft of the encoder is mounted on the application and the encoder monitors the position of the mounted shaft. The information they encode is thereafter available for data processing and/or control purposes.

The DP11SVN15B20S encoder is suitable for use in a range of different types of applications. It is suitable for use in motor control systems in consumer electronic equipment such as washing machines, dishwashers, and electric motors in cars. It can also be used in robots, as an angle sensor in 3D printers, and for machine vision applications. The encoder can also be used to accurately measure the angular positions of doors, windows, and other moving parts, as well as the angular position of any motor.

Working Principle

The working principle of the DP11SVN15B20S encoder is simple to understand. Encoders are made up of components such as rotary disks, photo sensors and counters. Enclosing each component is a light source (often a LED) and a receiver (often a phototransistor). When the rotary disk mounted on the shaft is rotated it passes in front of the receiver and the light source, interrupting the light beam between them. This interruption is then measured and sent to the processor, which then calculates the angular position.

The DP11SVN15B20S encoder is also capable of measuring velocity and acceleration, by measuring the time interval between successive pulses. As the angular speed increases, the time interval is reduced, and as the angular speed decreases, the time interval is lengthened. This helps the processor to calculate the angular velocity and acceleration at any given time.

To ensure that the measurement is accurate, the rotary disk on the DP11SVN15B20S encoder is marked with small magnets spaced at regular intervals. As the rotary disk rotates, the magnets pass a Hall sensor which triggers and outputs a digital signal to the processor, allowing for precise measurement of the angular position.

The main advantage of the DP11SVN15B20S encoder is its accuracy. As well as being able to measure up to 360° rotation and offering 0.05° resolution, the encoder is also highly reliable and robust. It is designed for harsh industrial environments and can withstand shock, vibration and extreme temperatures.

Conclusion

In conclusion, the DP11SVN15B20S is an accurate, reliable and robust encoder, suitable for a range of applications in consumer electronic, robotic and machine vision systems. It is easy to understand the working principle of the device, which involves the use of a rotary disk, photo sensors and counters to measure angular position. The encoder is capable of measuring up to 360° with a resolution of 0.05° and offers good stability in a variety of harsh industrial environments.
