I recently bought a pair of Electrocraft / Reliance ElectricE661 servos fitted with Renco 77678-319 encoders. Part number 661-028-0156
My Web-Fu must be getting weak as I have not been able tofind any real specs on either the servo or encoder. These units are used pulls from some equipment gettingparted out. They are available from multiple sources on ebay and other venues. Theyhave a 3/16” aluminum mounting plate with 2 quick release levers and a toothpulley for a 1/2 wide XL belt Mountingflange appears to be NEMA 34, Encoder shaft is ½” dia. and output shaft appearsto be 5/16” or 8mm ( I have not removed the pulleys.) Removing the encoder cover I see that only 4 wires areconnected to the internal 8 pin connector so no index is being brought out onthe existing encoder wire. Is anyone familure with these. Without specs it is hard tomake informed decisions on how to apply these for best use. OTOH I also recently got a great buy on a 2Nm Stepper withencoder feed back driver kit with all cables for $106 shipped. Now I see theprice has dropped even further.
