pöördeandurid

Pöördeandurid, also known as rotary encoders, are electromechanical devices used to convert the angular position or motion of a shaft into an electrical signal. They are widely employed in various applications requiring precise measurement and control of rotational movement.

There are two main types of pöördeandurid: incremental and absolute. Incremental encoders generate a series of pulses as the shaft rotates. The number of pulses corresponds to the amount of rotation, and the sequence of pulses can indicate the direction of rotation. These pulses are typically read by a counter, allowing for the calculation of position and speed.

Absolute encoders, on the other hand, provide a unique digital code for each distinct angular position of the shaft. This means that even after power loss and restoration, the encoder immediately knows its exact position without needing to be reset or moved. This makes them suitable for applications where continuous position tracking is critical.

Pöördeandurid find use in industrial automation, robotics, computer peripherals like mice and trackballs, medical equipment, and automotive systems. Their ability to accurately translate mechanical rotation into usable electrical data makes them indispensable components in modern technology. The choice between incremental and absolute types depends on the specific requirements of the application, such as the need for continuous position feedback or the ability to maintain position data during power interruptions.
