Avago Technologies (San Jose, CA) announced the AEDR-87xx series of 3-channel reflective optical encoder devices for use in low-power miniaturized motion control systems such as stepper motors, electrical actuators, piezoelectric drives, and portable medical appliances. The devices feature encoding resolution up to 318 lines per inch (LPI), support for 3.3V and 5V supply voltage for low-power applications, and dual analog outputs interfacing directly with an external interpolator for high-precision motion control measurements. The encoders feature three channel outputs including one index digital output; a built-in interpolator for 4x, 8x, and 16x interpolation; built-in automatic LED current regulation; encoding resolution of 318 LPI (up to 1.25 um pitch); and operating temperature range from -20 to +85 °C.
