Electronic products keep shrinking, packages become more and more compact. Along goes the necessity for smaller components. The same is true in electromechanical systems that require miniature motors: Without advanced nanotechnology, physics poses some limitations to the miniaturization of motors; hence the aim is to make everything else as small as possible. One example are the encoders..
Faulhaber has expanded its encoder product line with the addition of PA2-50 and PA2-100. These components for the feedback of DC-Micromotors realize 50 lines per revolution in a package measuring 6 mm in diameter (PA2-50) and 100 lines per revolution in an 8 to 12 mm package (PA2-100).
The heart of the designs is the optical AEDR-8400 chip from Avago Technologies, mounted on a flex-circuit in order to obtain a single compact package with a miniature footprint measuring 3.0 mm (L) x 3.28 mm (W) x 1.26 mm (H). Optimized for the AEDR 8400, a custom-designed codewheel maximizes the reflected light increasing the system’s efficiency and signal reliability.
Operating between 2.7 and 3.3 V DC, low-voltage battery applications run longer with more robust feedback signal reliability. Improved battery life comes from the low-inertia codewheel and a current draw of 8 / 8.5 mA.
