Technical Features

A special shielding design provides excellent shielding effectivness. The male connector has a “C” shielding for each signal and on the female connector side each differential pair is fully shielded by special shield blades around the signal pairs. Additionally, the “C” shaped shield blades provide for rugged mating and greatly reduce the possibility of contact stubbing.

Special female connector design for secure SMT application of the ERmet zeroXT with built-in coplanarity of 0.1 mm and built-in secure strain relief for the female connector. The strain relief is achieved by SMT/THR (Thru Hole Reflow) termination areas for the male and female shield blades. This secures no forces on the signal contacts.

Based on special design features like an innovative improved shielding and the availability of versions with SMT termination the ERmet zeroXT connector system provides enhanced signal integrity. Each 100 ohm differential pair is a transmission line with its own tightly coupled reference ground to control impedance and minimize connector noise.
Every wafer is shielded with a metal cage. The longest gap length to the outside of a wafer is 4 mm, which gives a very good shielding effectiveness.
The SMT termination secures a very constant impedance profile with no peaks and discontinuities as known from the plated-thru holes.

Already this word tells you, what performance you will get. The ERmet zeroXT provides you an excellent crosstalk, which means nearly no crosstalk: zeroXT
