The SROA46 split-type optical encoder is an absolute rotary encoder with precise counting. It is suitable for applications where the motor size is compact but high precision is still required.

Product characteristics

Ultra-thin design of 15.5mm, installation completed in 80 seconds, no calibration required.
Repeatability < ±5 arcseconds.
RS485 interface, compatible with multiple communication protocols.
Bidirectional asynchronous serial communication, 17bit per revolution (up to 23bit), 16bit for multi-turn.
Communication cable can reach up to 50 meters in length.
Rigorous EMC testing to meet harsh electromagnetic environment conditions.

Product advantages

Ultra-thin design with integrated installation.
Rigid connection without springs, providing better system rigidity.
One-click debugging, saving time and effort.
