ERmet ZD Backplane Connector 2 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 two pair wide configuration. The two pair wide
version is ideal for applications in combination with
ERmet 5+2 connectors because of the same width of 15.4mm.
