Encoders

Encoders are devices used to measure the position of a moving object. The DFS20A-A2BAD002500 is a type of absolute encoder, which operates on pulse-distance principles and is designed to measure the motion of linear servomotors.

Application Field

The DFS20A-A2BAD002500 is suitable for applications where precise, high speed motion control is needed, such as automation, robotics, machine tools, and more. It is particularly well-suited for pumps, compressors, conveyors, packaging machines, and other demanding applications.

Working Principle

The DFS20A-A2BAD002500 encoder operates on a principle called pulse-distance. It consists of a series of individual bearings separated by equally-spaced increments on a linear shaft. Each bearing is activated when a white or black line crosses its surface, which is outputted as a electrical pulse. This pulse is then sent to a processor to measure the distance the shaft has moved.

The DFS20A-A2BAD002500 encoder uses a birefringent-effect optical interface to measure the motion of the linear shaft. This interface consists of two linear elements that are positioned perpendicular to each other. The angles of the linear elements cause light passing through them to split into two, with one ray being transmitted through the first element while the other is reflected off the second. The two light rays are then received by the photodetector, which then produces two separate electrical pulses.

The linear position of the shaft is calculated by measuring the difference between the two pulses. The processor then sends the data to a computer, which can then be used to control the motion of the linear servomotor, ensuring the accuracy of the movement.

Advantages of DFS20A-A2BAD002500 Encoders

The DFS20A-A2BAD002500 encoder has several advantages. It is highly accurate, with an accuracy rating of ±0.002mm. It has a response time of 0.05ms, which allows for faster motion control. The encoder also has a high-temperature range, which allows it to be used in a wide range of applications. Additionally, the birefringent-effect optical interface ensures that the device is durable and can withstand shock and vibration.

Conclusion

The DFS20A-A2BAD002500 encoder is a type of absolute encoder, which uses pulse-distance principles to measure the motion of linear servomotors. It is well-suited for applications where precise, high-speed motion control is needed, and is capable of withstanding shock and vibration.
