ERmet ZD Daughter Card Connector 2 Pair Module The female daughter card connector is available with pressfit termination. The ERmet ZD provides internal ground shields for each pair of differential signals. Various module lengths are offered in two pair wide configuration. Additionally, each module has four pre-alignment pegs which provide easier alignment, improved rigidity, and better polarization. The layout grid facilitates integration with conventional 2mm HM (IEC 061076-4-101) connectors. The two pair wide version is ideal for applications in combination with ERmet 5+2 connectors because of the same width of 15.4mm.
