Encoders are widely used to provide precise position, angle and speed detection or replacement for contact switches. Among them, E6C3-AN1E 256P / R 2M can drive "power-off data protection", which can realize high-precision position sensing in a variety of applications. This article will introduce the application fields of E6C3-AN1E 256P / R 2M and its working principle.

E6C3-AN1E 256P / R 2M is a high-precision incremental rotary encoder suitable for many fields. It can be used in the industrial field to measure the rotation speed and angle of motors, such as in water treatment, conveyor system and printing machine, as well as in valves for measurement of the opening degree. In the medical field, it is often used for the control of medical instruments such as ultrasonic imagers. Moreover, in the automation field, it is used as a feedback device of the robot hand to measure high-precision motion, as well as in computer numerical control (CNC) working benches and coordinate measuring machines for accuracy position detection.

The working principle of E6C3-AN1E 256P / R 2M is a classic technology called photoelectric incremental encoder, also known as the photoelectric rotary encoder, which is divided into two types: incremental encoder and absolute encoder. The main difference between the two types is the way to output the information. The E6C3-AN1E 256P / R 2M belongs to the increment encoder, which emits a series of simple electrical pulse signals in response to rotation, without being affected by external power failure. It has two output signals, A and B, which are usually 90° out of phase and are processed by external circuits to form the counting signal. The combination of A and B phases increases the resolution of the encoder, so that the incremental pulse information of the rotation can be transmitted more accurately.

To ensure the accuracy of rotation detection, E6C3-AN1E 256P / R 2M equips with a technology called power-off compensation, which is an original power-off data memory technology developed by Panasonic Corporation. During power-off, the encoder will continuously detect the rotational condition and store the current data in the internal RAM. After power-on, the encoder will output the previous data from the RAM, and a stream of pulse signals is generated according to the current position of the encoder. During power fluctuations, this technology protects and maintains the original measurement data, minimizing the distortion of the position information and providing a more stable working environment.

In summary, E6C3-AN1E 256P / R 2M has many advantages and is widely used in industrial, medical and automation fields, such as in speed and angle detection of motors, medical instrument control, robot hand control, CNC tools detection and coordinate measuring machine. Its power-off data protection technology keeps the encoder position and measurement consistency in a power-off environment, which dramatically increases the accuracy and stability of work and substantially reduces errors.
