Design News and Allied Electronics would like to send you a check for CAP CER 0.1UF 50V 20% RADIAL 3 from the ground up. It is based on an Avago quadrature encoder with 1,000 pulses per revolution. Because the encoder mounting requirements dictate fairly precise mechanical location and stability, it was necessary to machine a whole new housing and drive shaft, rather than using the stock parts. The housing is machined out of 6061-T6 aluminum billet and carries four precision sealed roller bearings to support the drive shaft. The drive shaft is machined from 304 stainless steel. The stock helical drive gear was utilized with an added miniature precision thrust bearing, instead of the stock thrust washer. There are locating pips machined into the encoder mounting flange, which takes care of aligning the encoder head. The matching code wheel is also stainless steel for survivability. The electronics are contained on a single printed circuit board mounted above the encoder. The assembly is protected by a screw-on cover machined from billet aluminum. DN 70067793 1 EDWARD A.
