Best Price 12 Bit SSI Multi-Turn Absolute Encoder Rotary encoder:Absolute rotary encoders divide into single-turn absolute encoder and multi-turn absolute encoder. The code track is designed by using Gray code, matrix code, cursor code, pseudo-random code, etc. When the shaft rotates, there is a code output corresponding to the position. From the change in code size, the position of the forward and backward directions and the displacement can be distinguish without direction judgment circuit. It has an absolute zero code. When power is outage or turned off, when it is turned on and re-measured, the code of the power outage or shut down position can still be accurately read, and the zero code can be accurately found. ROUNDSS Absolute rotary encoder provide multiple interfaces:RS485, RS422, RS232, SSI, MODBUS, Canopen, parallel or analogue. The sensor has multiple shaft diameters are optional.

Absolute rotary encoder is featured on high resolution. Generally, the higher resolution, the higher accuracy. But the absolute rotary encoder can not decide the accuracy of the whole system. Absolute encoder, motor and driver are the three main parts in servo system. Even if the absolute rotary encoder is high in resolution, motor can not match encoder, the total accuracy will be low also. So it is not the higher resolution of encoder, the better accuracy of motor. Suitable resolution is the best. Currently 17 bit resolution can meet most of application.

Absolute rotary type encoder is widely applied to angle, length and motion control in industrial system because of the sole position. The sole location function of absolute rotary type encoder is obviously better than incremental encoder. It is with high resolution and high accuracy. So absolute type encoder is more and more used in industrial control. In mechanical, absolute rotary encoder is similar to incremental type encoder. There are also solid shaft absolute encoder and hollow shaft absolute encoder, which meets different mounting requirement.
