Anyone know a good source Avago, US Digital and Renco come to mind. By hollow-shaft, do you mean "kit" encoders? Real hollow-shaft encoders with bearings are quite expensive, BEI and Danaher come to mind. The Kit encoders have a free-floating wheel that is supported by a shaft on the motor or machine, and have no bearings. They are much cheaper due to this. You can search on Digi-Key, Mouser and Avnet. Renco has been bought out by Heidenhain, but they are still available. Watch out for the CUI AMT-10x encoders at Digi-Key, they have a lag responding to acceleration, and may not be well-suited to CNC systems such as EMC2. Jon |
