Encoders

Absolute encoders are precision devices used for the measurement of shaft rotation or linear position. An absolute encoder is a device which outputs a code representing the exact position or angle of the shaft. The encoded output can be used in position feedback systems or as the input to a servo motor or stepper motor. Encoders are becoming increasingly popular due to their accuracy and reliability.

DFS20A-A2BAC002048 Application Field and Working Principle

The DFS20A-A2BAC002048 is an absolute type encoder from Avago Technologies that is used for rotation measurement, angle measurement and position control in a variety of industrial and commercial applications. This encoder features shaft and housing sizes of 8.8mm and 21mm respectively, operating temperatures from -20°C to +105°C, an optional oxygen index of IEC 61340-3 and an electrostatic discharge immunity level of EN61000-6-2.

The working principle of the DFS20A-A2BAC002048 encoder is based on optical sensors that detect the exact position of the rotating or linear motion shaft. The output of the encoder is in a binary form that is proportional to the original electrical signal which is generated from the shaft\'s motion. The encoder decoding software receives the binary encoded output and converts it into a digital value which can be displayed on a display unit. This makes it easier for the user to interpret the data.

The DFS20A-A2BAC002048 encoder provides a resolution of two binary bits per pulse which corresponds to in increments of 90° for each rotation of shaft. The number of pulses is equal to the number of slots, which is usually 8 slots. The output for each pulse is two binary bits, 0 and 1. Depending on the number of slots, the output can have a maximum of 16 possible combinations, which translates into a resolution of 0.225° per increment for each rotation of the shaft. The encoder has a maximum operating speed of 5000 rpm and a repeatability of ±0.1°.

The DFS20A-A2BAC002048 encoder is used in a variety of applications, such as automation systems, robotics, medical instruments and a variety of industrial motor control systems. It is designed with a sturdy and durable construction and operates smoothly in a wide range of ambient temperatures. The encoder can be used in hazardous environments due to its oxygen index rating and electrostatic discharge immunity level.

The DFS20A-A2BAC002048 absolute encoder is a reliable, compact and easy-to-use device that is ideal for a variety of position and angle measurement applications. Its high resolution, accuracy and robust construction make it an ideal choice for industrial and commercial applications.
