Encoders 63KS256-020

Encoders are important within a wide variety of industries, providing a reliable means to measure rotational motion and velocity. The 63KS256-020 is a single-ended incremental encoder designed primarily for industrial applications. This article will discuss the 63KS256-020’s application field, as well as its working principle.

Application Field

The 63KS256-020 encoder is designed for environments requiring an incremental output, such as motor controls and Position feedback devices. Due to its size, the 63KS256-020 is primarily used in automotive, medical, industrial, and robotics applications.

The 63KS256-020 is designed to operate over a temperature range of -40 to +85 °C, and offers a robust mechanical construction. It has a robust operating torque of up to 5Nm, as well as excellent noise immunity and dust resistance. The operating voltage range is 12-36V DC.

Working Principle

The working principle of the 63KS256-020 encoder is based on two mechanical components: the "spindle" and the "code wheel". The spindle is connected to the motor shaft and rotates, while the code wheel is mounted on the encoder\'s body and does not rotate. The code wheel is made of transparent glass, and has a series of holes in it arranged in a pattern.

Each hole in the code wheel is associated with a specific binary bit. When the code wheel rotates past the spindle, a light source beams a beam of light through the holes in the code wheel. As the spindle passes through the holes, the light is sensed and changes state. This change in state produces two output signals, A and B. Each of these signals is connected to a digital counter circuit, which counts the number of times the light passes through the code wheel.

The two output signals produced by the 63KS256-020 encoder are combined to form a quadrature output. These signals are then used to determine the speed and direction of the motor shaft. By counting the number of transitions between the two output signals (A and B), an accurate measure of the rotational angle can be obtained. The number of rotational angle transitions is known as the "counts per revolution" (CPR).

Conclusion

The 63KS256-020 encoder is a reliable incremental encoder suitable for a variety of industrial and automotive applications. It is designed to operate over a temperature range of -40 to +85 °C, and offers excellent noise immunity and dust resistance. The 63KS256-020 features two output signals, A and B, which are combined to produce a quadrature output and can be used to determine the speed and direction of the motor shaft. By counting the number of transitions between the two output signals, an accurate measure of rotational angle can be obtained.
