Description
Multiturn absolute rotary encoder utilizes analog capacitive measurement method of angle of input shaft. No power is needed to count the number of turns of input shaft. After power is applied the encoder position can be read out using the SPI bus with resolution of 4096 turns and 1024 steps per turn. The SPI bus is synchronous and the encoder acts as SPI slave. Clocking and bus control and control of encoder position information are provided by master device. SPI transfer speed is 1 Mbps maximum.
