Encoders: DFS20A-A2BAD005000 Application Field and Working Principle

Encoders are widely used as transducers for linear displacement measuring devices or digital input devices in the fields of instrumentation, analogue-to-digital conversion and industrial automation systems. Among these encoders, the DFS20A-A2BAD005000 quadrature encoder is particularly notable for its high-precision performance and easy installation. This article offers an overview of the application field and working principle of the DFS20A-A2BAD005000 quadrature encoder.

Application Field

The DFS20A-A2BAD005000 is a low-profile large-diameter encoder that features a 360 degree angle of rotation, maximum speed of 400 rpm, 4 millisecond response time, 2 kHz frequency rate, and a resolution of up to 250 counts per revolution. Suitable for general purpose motor control, the DFS20A-A2BAD005000 is perfect for applications requiring precise speed, position and direction detection. The encoder can easily be mounted on the motor shaft for measuring linear velocity and can be used in motor controllers, robots, Programmable Logic Controllers (PLCs), and other automation systems.

Working Principle

The DFS20A-A2BAD005000 encoder utilizes a quadrature output signal to generate one phase of high-resolution pulse per revolution. The encoder employs a rotary encoder disc, which is composed of an array of magnetic and optical sensors. The magnetic sensors detect changes in the magnetic field caused by the rotation of the encoder disc, while the optical sensors detect the changes in light intensity caused by the rotation of the encoder disc. This signal is then converted to a pulse train output signal, which can be used to calculate position, direction and speed.The encoder has two channels, A and B, which are 90 degree out of phase with each other, and are used to generate two pulse trains that are 180 degrees out of phase with each other. The A channel signals the start of a cycle and the B channel signals the end of a cycle. This allows the encoder to measure both speed and direction of rotation.

Conclusion

The DFS20A-A2BAD005000 quadrature encoder is a low-profile large-diameter encoder that is suitable for a wide range of motion control applications. It features high accuracy and fast response time, making it an ideal choice for motor controllers, robots, PLCs, and other automation systems. The encoder’s quadrature output signal allows it to measure both speed and direction of rotation, thus providing precise motion control.
