AS35-M23S Datasheet | Broadcom

Description The Broad® AS35-M21S/M23S series encoder is a high-resolution optical absolute encoder module, which offers up to 23 bits single-turn resolution. This absolute encoder series is a module encoder consisting of a patterned disk, a light source, and photosensitive elements to translate the mechanical motion into electrical signals. The single-turn encoder is available with an RS-485 standard pliant munication protocol and supported by a half-duplex differential line transmissions driver. These features offer good noise immunity for a robust data transmission at 2.5Mb/s in harsh industrial applications. Alternatively, the industry standard single-directional Synchronous Serial Interface (SSI) protocol is offered at a data transmission rate of 1 MHz. One of the key advantages of the AS35-M23S series is the low-profile module assembly. After assembly, the encoder module is only 16.5 mm in overall height. With fast installation and easy one-touch calibration process, the AS35-M23S series is well suited for direct motor assembly into small motors size of 40 mm and above. As the product is intended for industrial applications, ESD protection circuitry has been designed to meet the industry standard of IEC-61000-4-2 for class 4 applications.
