($21 from the US Digikey) I like it. Plus the push to select feature is nice too. I am a little leery about the low counts per revolution. For eight bits of resolution, that would be, 256 bits per full scale/32 counts per rev. = 8 rev. In real use, is eight turns a bother? Actually, it might be safer. I did see this encoder: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=601VCS-ND at $30, with 128 counts = 2 turns, but no detent or select switch, though I suppose these could be added. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending) ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
