I have these on my first CNC conversion, and they haven't caused any problems, but at the same time I don't like them the way I like the Neutrik connectors (and Lemo connectors). The Neutrik Speakon connectors use multi-leaf silver contacts. How do they compare in the spectrum of desirability? (I have only used them for servo motor drives, at about 300V) Another option for an A-axis is a hybrid D-sub. That lets you have the power and data in one connector, all gold-plated. http://uk.rs-online.com/web/p/solder-d-sub-connectors/5427573/ The data pins on D-sub are good for 5A, but the big power terminals can do 40A. An interesting possibility with these connectors is that they can also have pneumatic inserts, which could be handy for a clamped A axis. http://uk.rs-online.com/web/p/d-sub-connector-contacts/6659904/?origin=PSF_435844|acc -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
