The one I have on the rear end of that 1hp motor, an Omron 1000 ppr, cost me $21 on fleabay 6 years ago. Its a differential model I'm converting to ttl in a pair of rs485 to ttl interfaces that cost about $2 each, driving a 5i25 card. NO optics in that path. Absolute it is not, but if the encoder tracks, who cares. Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
