Encoders may be defined as devices capable of measuring distances, angles, or speeds. They convert linear or angular motion into a form of digital information that can be stored, manipulated and relayed in computers and other electronic systems. A DP11SHN20B20S encoder is a type of encoder designed to provide a digital output signal representative of the linear or angular motion of an object.

Application Field of DP11SHN20B20S Encoder

DP11SHN20B20S encoders are typically used in servo and stepper motor applications to accurately measure and control the speed and position of the motor. These encoders can also be used to measure the speed of a revolving handwheel or the rotation speed of a grinding wheel. The encoders are also used in various robotic and automation systems, providing feedback data that can be used to adjust the motion of the robot to maintain the desired precision and accuracy. These high-precision devices can provide the necessary instantaneous data to locate and track objects in automated assembly processes.

Working Principle of DP11SHN20B20S Encoder

The DP11SHN20B20S encoder works by combining a light source, typically a light-emitting diode (LED), with a position-sensitive light-receiving element such as a photocell or photodiode. When the encoder move simultaneously, the LED light changes intensity as it passes through the position-sensitive light-receiving element. This is how motion is converted into a digital output signal.

The encoder also uses an optical disc, which is attached to the motor shaft. As the disc rotates, its segmented pattern interrupts the light passing through the optical sensor, generating a series of square waves whose frequency is proportional to the angular velocity of the motor shaft. The frequency of these square waves is then processed by an on-board electronics module to generate various types of output signals such as a 3-phase pattern, a single-ended signal, or even a digital signal using a pulse output.

In addition, the DP11SHN20B20S encoder is also equipped with a switch that can be used to detect the rotational direction of the motor shaft. This swith, known as a “zero pulse”, is positioned at the start of the movement and can be used to zero the encoder’s output to accurately measure the angular position of the motor shaft.

Conclusion

The DP11SHN20B20S encoder is an extremely versatile and reliable tool for a variety of motion control systems. It provides an accurate and stable digital output signal that can be used to measure linear or angular motion, speed, and position. This information can then be used to feedback data to motor controllers and other electronic devices in robotic and automation systems.
