Wanted: Renco Encoder (or Electrocraft E643 DC servo w/ encoder) to suit Yuasa 4th Axis

Post by charlie »

Hi all, my 4th axis unit developed a leak which resulted in the encoder failing. I'm keen to replace the encoder if possible. The original servo is an Electrocraft E643 DC servo (by Reliance Motion Control) and the encoder is a Renco PN: 77678-157. Any help or leads would be much appreciated.
