Working Principle

The DP11H2020A20S encoder operates using a series of optical sensors to detect rotary motion. Inside the encoder, a transparent disk with a series of concentric lines on it is mounted on a rotating shaft. These lines are detected by an optical sensor, which then sends a signal to the encoder’s integrated circuit. The IC uses the signal to calculate the angular position of the disk. This information is then sent to the encoder’s output in the form of a PWM signal.

The PWM signal produced by the encoder is a pulse-width encoded signal. This signal can be used to calculate the angular position of the shaft. It is also capable of producing a variety of output signals, such as sine, cosine, or square waves. The PWM-encoded signal can also be used to control position, velocity, and acceleration of a rotating motor.

The accuracy of the DP11H2020A20S encoder is guaranteed by its high resolution and error-correction circuit. The error-correction circuit continuously checks and corrects errors in the signal produced by the optical sensors. This ensures that the output from the encoder is always accurate and reliable. Additionally, its high resolution allows it to detect even small rotary motions.

In summary, the DP11H2020A20S encoder is a modern, reliable, and accurate rotary encoder that is suitable for use in a variety of industrial applications. Its wide range of features ensures that it is durable and reliable, while its high resolution and error-correction circuit guarantee accurate output. The PWM-encoded signal produced by the device can be used to control position, velocity, and acceleration of a rotating motor.
