Absolute Encoders

Same Sky's absolute encoders output 12 bits or 14 bits of absolute position information with Serial Peripheral Interface (SPI), RS-485, or Synchronous Serial Interface (SSI) communication. Based on capacitive technology, our absolute rotary encoders are not susceptible to contaminants that can plague encoders in industrial applications. Our absolute encoders offer compact packages, low current draw, and wide operating temperature ranges.
