Product Description
Product Overview
The AEDR-8000 Encoder series is a reflective surface mount optical encoder designed for rotary and linear motion control. It offers a direct replacement for the HEDR-8000 series and provides single-channel incremental and two-channel quadrature outputs for direction sensing. With a single 5V supply and TTL-compatible outputs, it is suitable for various applications requiring precise motion sensing at a competitive price, especially in high-volume consumer products where space and weight are critical.
