Avago Technologies announced a new series of 3-channel reflective optical encoder devices, the AEDR-87xx. The devices are ideal for use in low power miniaturized
motion control systems such as stepper motors, electrical actuators, piezoelectric drives and portable medical appliances.
Expanding upon previous generation devices, the new AEDR-87xx with encoding resolution up to 318 lines per inch (LPI) supports 3.3V and 5V supply voltage for low power applications and dual analog outputs interfacing directly with external interpolator for high precision motion control measurements. The devices are packaged in industry’s smallest form factor for 3-channel reflective optical encoder. “Reflective optical encoder technology is vital to many miniaturized motion control systems. As modern appliances get smaller in size and consume less power, so too are the critical components such as a motion control encoder embedded inside many of these appliances,” said Hassan Hussain, vice president and general manager of the Motion Control Product Division (MCPD) at Avago. “Avago’s latest AEDR-87xx is the best-in-class reflective optical encoder solution with added flexibility addressing a wide range of design challenges for modern miniaturized motion control systems.”
