AR25-AS1B-A18T

AR25-AS1B-A18T is a smart programmable 25bit reflective absolute single-turn encoder ASIC that is designed to cater the growing demand for space-constraint applications. Employing the advance reflective optical-encoding theory, the AR25 series offers high position accuracy with correction algorithm, which is unattainable by the magnetic encoders. In addition, the AR25 also provides differential analogue sine/cosine or digital incremental ABIUVW signals with configurable CPRs and pole-pairs. Standard protocols consist of encoder serial link (ESL), RS-485, synchronous serial interface (SSI), and serial peripheral interface (SPI 4-wire). Typical applications are robotic automation and engineering, factory automation and drone, medical and dentistry devices and equipment, high-accuracy portable and handheld devices, miniature motor, servo motor and linear actuator, through-shaft motor, gear motor and speed reducer.
