AEDR-871x 3-Channel High Resolution Reflective Incremental Encoder (Digital Outputs)

The Avago AEDR-871x is a 3-channel reflective optical encoder device providing dual channel quadrature digital outputs and an index channel digital output. With encoding resolution up to 318 lines per inch (LPI) and built-in 4x, 8x and 16x interpolation, the device enables great flexibility and versatility in resolution range. The quadrature (AB) digital outputs are TTL-compatible enabling the device to interface directly with many digital signal processors (DSP) and host processors. As such, the device can be easily designed in and integrated into existing motion control system. The AEDR-871x houses an LED light source and a photo-detecting circuitry in a compact package. The miniature package coupled with low operating 3.3V option allows the device to be used in a wide range of space-constrained, low-power applications like portable devices in which space and power dissipation are primary concern. The device is designed to operate over -20 to +85 °C temperature range suitable for both commercial and industrial end applications. Available Product Options: AEDR-8710-102/100 AEDR-8711-102/100 AEDR-8712-102/100
