Encoders are devices used to transmit the position or motion of a machine part to an externally-located controller. DFS25A-A2BAE000720 is a type of rotary encoder with 4-20mA output for the industrial or automation control area. It is particularly suitable for high-resolution and high-precision motion control applications, such as multi-axis motion coordinate systems, three-dimensional coordinate systems, robots, and so on.

Application Field

DFS25A-A2BAE000720 rotary encoder is mainly used for industrial applications such as intelligent manufacturing, automation, robotics, mechanization, and CNC tools. It can be used as the position feedback signal device for industrial servo system. Besides, it can also be used in consumer electronics, as well as in medical and vending machines. These encoders can also be used in various measuring and testing operations for determination of distance, velocity, angle, and linearity.

Working Principle

The DFS25A-A2BAE000720 rotary encoder generally consists of a code disk, an optical detector including a light-emitting diode (LED) and a light-receiving photodiode, and a signal processing circuit. When the code disk rotates, the LED and photodiode form a photoelectric displacement detector. The detector will detect the difference in the reflection amount of the code disk, and generate two square-wave signals, which are Phase A signal and Phase B signal. Then the signal processing circuit will convert the two signals into a signal representing the displacement, which is then sent to the controller, or other control system.

DFS25A-A2BAE000720 rotary encoders adopt single-loop technology, which has high precision and stability, and ensures that the output signal’s amplitude and linearity remain stable in a wide frequency range, so as to ensure the accuracy of position feedback in various environments.

Advantages

DFS25A-A2BAE000720 rotary encoder has a small size, long lifetime, fast speed response and high accuracy, which is up to 0.1°. It is also resistant to noise, so it can work reliably in harsh environments. It uses low-power optical collision technology, so it consumes less power than other types of encoders. The output signal is a 4-20mA two-wire current signal, making it easy to be connected with PLCs.

Conclusion

DFS25A-A2BAE000720 rotary encoders are widely used in industry, with advantages such as high precision, fast response, and low power consumption. The technology behind the encoder is robust and well-established, allowing reliable feedback even in harsh environments. With its features and abilities, this encoder is the ideal choice for industrial and consumer products.
