Under what circumstances should I choose an absolute encoder

We all know that there are absolute encoders and incremental encoders for rotary encoders. The two look the same, but the performance is quite different. Some designers should be guilty of choice phobia and choose incremental encoders. How is the instrument? Or should I choose an absolute encoder? Today we will explain in detail the working principle, advantages and application fields of the absolute encoder, and hope it will be helpful to your choice.

Absolute encoders are mainly used in industries such as packaging, textiles, elevators and other industries that only require measurement of speed and have low requirements for absolute position measurement. Absolute encoders are used in high-precision machinery and equipment or steel, ports and cranes. Due to the relatively high requirements for measurement accuracy in other heavy industry industries, absolute value encoders are used in more cases. In these heavy industry applications, due to the harsh working conditions, the requirements for the shock and vibration resistance of the absolute encoder are relatively high.

Each position determined by the mechanical position of the absolute encoder is unique. It does not need to be memorized, does not need to find a reference point, and does not need to be counted all the time. When it needs to know the position, when to read its position. In this way, the anti-interference characteristics of the encoder and the reliability of the data are greatly improved.

Absolute encoders have been more and more widely used in angle and length measurement and positioning control in various industrial systems because each position is absolutely unique, anti-interference, and does not require power-down memory. The absolute encoder is determined by the uniqueness of each position by the mechanical position. It does not need to be memorized, does not need to find a reference point, and does not need to be counted all the time. When it needs to know the position, when to read its position. In this way, the anti-interference characteristics of the encoder and the reliability of the data are greatly improved. The absolute value encoder is sufficient to withstand the weight of the pipeline and withstand mechanical shocks. It is a direct motor connection type supported by an intermediate bracket, which is convenient to install and disassemble, and has a compact structure. , Safety and energy saving.
