Rotary encoder

These absolute rotary encoders are designed for subsequent electronics that support the unidirectional SSI interface, and can be programmed to specific measuring tasks. Their single-turn resolution of 8,192 position values per revolution can be reduced by any whole number. This scalability allows the encoder to adapt to specific measuring tasks. And the selectability of the code (gray or pure binary) and the transmission format (tree or right-justified) increases the flexibility.
