CompactPCI Express [cPCIe] Board Dimensions
cPCI Express [6U] uses 2mm 'Hard Metric'; IEC 1076-4-101, a number of different pin
arrangements. Normally the outside Ground rows (which are compression
pins) 'Z' and 'F' are not counted as pins. OEM pin numbering may be by
cPCI or in accordance with IEC 61076-4-101 (which is reversed). The term
"Hard Metric" only means that metric dimensions are preferred ~ with-out
regard to inches. Connector manufacturers [vendors] are listed on the
main CompactPCI Express [cPCIe] page.
The types below are counting signal pins (not the ground rows), as
indicated on many data sheets:
Type A; 110 pins, Keyed (J1/J4),([25 rows x 5 columns] - [3
rows x 5 columns of Key])
Type B; 110 pins (J2/J5), [22 x 5]
Type B; 95 pins (J3), [19 x 5]. This is also used as P0
with VME64
Type C; 55 pins [11 x 5]
Type AB; 95, 110, or 125 pins
There are other connector types:
Type L; # contact cavities to accept power insert contacts
Type M; # contact cavities to accept power insert contacts/with
half the connector having normal pins

CompactPCI [cPCI], PXI, or PCI Bus page.
cPCI and PXI use the same form factor [card size]. cPCI and PXI use the
electrical bus standard of PCI [with a few changes].
