Commonly used to upgrade old existing DC servo motors to be compatible with the Centroid Allin1DC. See example servo motor encoder upgrade here. Replaces Tachometers, Resolvers and Low-resolution Encoders. Upgrade existing DC servos to the latest technology for silky smooth closed loop CNC operation. Centroid stocks these high resolution, 5vdc, quadrature differential encoders in several commonly found shaft sizes. Encoder to Encoder cable pigtail included which allows plug and play compatibility with Centroid Encoder Cables, no crimping or soldering needed. Please measure the servo motor encoder shaft diameter before ordering. Find more technical how-to information on Encoders here.
