ERmet ZD
High Speed Differential Hard Metric Connector System
ERmet ZD Male and Female Module with Pressfit Termination
Description
The ERmet ZD is specifically designed for high speed
differential signaling in telecom applications at data rates of up
to 5 Gbits/second. This robust, high performance, modular
connector system is also designed to be used in conjunction
with the 2 mm Hard Metric (IEC 61076-4-101) family of
connectors. It shares the chassis and board design features
along with common layout references.
The connector meets the electrical performance requirements
of high speed, low voltage differential signaling. The ERmet ZD
connector family is available in pressfit versions. The back-
plane module is a male pin header that has three mating
levels. The ground shield and signal pins mate sequentially at
1.5 mm intervals.
The robust mechanical design and excellent signal integrity
are a result of the internal differential shielding scheme and the
“L” shaped male shield blades. The inherently rigid male
shields stand higher than the signal pins and surround each
pair. An improved guidance feature completes the rugged
mechanical design.
Optimized grid design to improve the RF characteristics.
Easy and economical trace routing achieved by in line-design
of signal and ground pins.
Simulation models available upon request.
Technical Features
• Design: Wafers with individually shielded pairs of contacts.
• Contacts: Low noise, dual beam, leaf contacts with one
ground blade for every pair of signals.
• Wafer pitch: 2.5 mm from wafer to wafer.
• Pitch between signal pins: 1.5 mm between pairs
(within wafer).
• Pitch between pairs: 4.5 mm (within wafer).
• Ground arrangement: In line with signals at termination and
surrounding shield.
• Multiline Crosstalk < 3% at 100 ps
• Differential Impedance: 100
Ω
±10%
• Power Modules: Closed entry, vertical female backplane
modules with stamped blades.
• Alignment Features: Improved pre-alignment guide and
polarizing features, 4 rigid blades for all modules.
• Modularity: Modules are available in two widths and a
variety of lengths to integrate within typical Eurocard
designs utilizing 5 and 8 row, 2 mm HM connectors to
IEC 61076-4-101.
