> Can you tolerate multiple insulation displacement connectors on a ribbon > cable, and not have a backplane at all? That is a trick you can do with the DIN 41612 connectors. You get chassis m= ount wire wrap ones and use standard IDC ribbon cable connectors on them. I suspect that a backplane using DIN 41612 connectors would suit the OP fin= e, as the dimensioning of the connector is defined by the rack mount system= .. The single row 32/dual row 64/triple row 96 pin format will stand on end = in a 3U rack unit. The nominal board size of 100mm wide will go in 3U rails= on edge using these connectors. --=20 Scanned by iCritical. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
