The AEDS-8300 series offers options of either single channel or two-channel quadrature digital outputs. Being TTL compatible, the outputs of the AEDR-8300 series can be interfaced directly with most of the signal processing circuitries. Hence the encoder provides great design-in flexibility and easy integration into existing systems. The AEDR-8300 series is available in four resolutions, namely 36, 75, 150 and 180 lines per inch (LPI) ( 1.42, 2.95, 5.91 and 7.09 lines per mm respectively). This range of resolutions caters for different design and application needs.
