ERmet ZD Backplane Connector 3 Pair Module
The male backplane header is available with pressfit termina-
tion. The ERmet ZD supports three levels of sequential mat-
ing. The “L” shaped shields are robust mechanical structures
that provide an ideal differential
environment as well as protecting the signal pins and resisting
deflection that could cause stubbing. Various module lengths
are offered in three pair wide configuration. The three pair
wide version is ideal for Eurocard backplane designs with
0.8 inch card spacing.
