ERmet ZD
High Speed Differential Hard Metric Connector System
Vertical Male Connectors 4 Pair
The ERmet ZD 4 pair male connector provides in the 10 wafer
version 40 contact pairs (80 signal contacts and 40 ground
contacts). This series supports three levels of sequential
mating.
The male 4 pair is available with pressfit termination. 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 length are offered in four pair wide configura-
tion. The layout grid facilitates integration with conventional
2 mm HM (IEC 061076-4-101) connectors.
