Reflective optical encoders for portable medical devices by Avago Technologies
AEDR-87xx three-channel reflective optical encoder devices from Avago Technologies (San Jose, CA) have use in low-power miniaturized motion control systems such as stepper motors, electrical actuators, piezoelectric drives, and portable medical devices. They feature encoding resolution up to 318 lines per inch (LPI; up to 1.25 µm pitch) and built-in light-emitting diode (LED) current regulation, and support 3.3 and 5 V supply voltage for low-power applications and dual analog outputs interfacing directly with an external interpolator for high-precision motion control measurements.
