An encoder is a device used to measure the motion of an object and convert it into electrical signals. OPE1275H-256 is one type of absolute encoder with a high resolution (256 counts per revolution). This encoder can be used to accurately measure the rotary motion of a shaft or linear motion of a rifle. Here we will discuss its application field and working principle.

OPE1275H-256 consists of a light source and a photodetector. It contains a large number of photoelectric sensing elements built into the body. Each sensing element produces a pulse when the optical encoder disk and the sensing window pass by it. The number of pulses shows the displacement of the object.

The encoder has a wide range of applications mainly in motor speed, feed rate, angular measurement, and position control. OPE1275H-256 encoder can be used in servo motors, motor drives, frequency converters, and various industrial applications to control the speed of machinery. This type of encoder is widely used in brushless DC motors and stepper motors as its high resolution ensures precise motion.

In the case of the OPE1275H-256 absolute encoder, the pulse output data corresponds to the shaft (rotational) or Linear (translational) position of the object. The absolute encoder generates a variety of binary code levels depending on the distance. The output code of the OPE1275H-256 provides a resolution of 256 states / pulse per revolution Thus, it is able to accurately capture the rotational angle of a shaft or linear position.

OPE1275H-256 absolute encoder works based on the principle of optical incremental encoder. The light source emits the light which is collected by a photodetector. The sensing elements of the encoder disk will encoder disk will interrupt this light when the disk rotates. Each time this interruption occurs, a pulse is created which is registered by the encoder.

The emitted light passes through the encoder disk which contains lines that interact with the light to create a dark/light pattern. When this pattern of light/dark moves across the photodetector, the output of the photodetector changes correspondingly. This phenomenon creates an electrical pulse whose information is processed by the encoder.

OPE1275H-256 absolute encoder can be used for digital position and motion control. With its high resolution, motion accuracy can be guaranteed and designed for various kinds of industrial applications. This type of encoder is also suitable for brushless DC motors and stepper motors due to its favorable performance. Moreover, the encoder allows for a variety of communication modes and can provide necessary data for digital control systems.
