ERNI has announced the availability of its MicroSpeed connector system in SMT technology for high-speed applications.

The modularly designed, shielded connector system consists of two terminal banks and two outwardly arranged shield plates. Designed for use in space-saving board-to-board connections with a 5mm circuit board distance, the product features a longitudinal pitch of 1mm and transverse pitch of 1.5mm.

The differential signal pairs can be arranged horizontally or vertically. Good crosstalk behavior is achieved with a vertical (transverse to longitudinal direction) configuration of the signal pairs and the pairing arrangement of signal and shield contact pairs. Measurements have demonstrated that crosstalk is <2 percent at 100ps and reflection factor is <5 percent with board thickness of 1.6mm.

The impedance is 100 ohms for differential signals and 50 ohms for single-ended signals. While the signal terminals are done in SMT, the user can select between two terminal options for the ground contacts depending on the application: SMT or THR connection. The ground contacts also assure robust strain relief of the connector. The length of the connector modules is 27mm with 50 signal contacts and 2 shield plates.

Target applications include modern telecommunication and data transmission systems with speeds up to 10GBps as well as technologies in the fields of measurement, medicine and the government applications.
