Opto-encoder ICs are blue, reflective & lensless
At SPS/IPC Drives 2015 in Nuremburg, iC-Haus will introduce its new encoder ICs which are described as blue, reflective and lensless. Specifically designed for flat encoders, with multiple diameters and line counts, the iC-PR reflective encoders feature dual analogue/digital output options, selectable interpolation factors and high resolution.
The iC-PR encoder chips combine optimised reflective scanning with a blue LED and output signal conditioning in one flat 4x4mm2 optoQFN package, generating low-jitter encoder quadrature signals with index and analogue sine/cosine signals directly. Index gating options and interpolation factor are easily selectable via pin programming. Output frequencies up to 1.6MHz enable motor speed control of 20,000rpm. The small scanning area and blue LED reduce power consumption of the reflective encoder module.
iC-PR devices control LED current to compensate for ageing and temperature effects; lensless operation simplifies SMD mounting and increases the operating temperature range to -40 to +100°C. iC-PR devices are suited for industrial applications like stepper motors, electrical actuators and drives, and miniaturised motion control systems in general. Compact iC-PR encoders also provide a robust solution in commercial applications. iC-Haus provides evaluation boards and matched reflective code discs for easy evaluation in your application.
