ERmetTen (8+2) 2 mm pitch connectors

22 May 2002 Interconnection

Erni expanded its metric (2,0 mm grid) connector series with a new connector family in order to meet the increasing demand for higher density backplanes as well as daughter and plug-in boards. The 10 row ERmet connectors are designed with 200 signal pins and 50 grounding pins (total 250 pins) on a compact 50 mm long connector using Pressfit technology (Figure 1).

This permits multiple pseudo coaxial configurations to be created in a limited space, fulfilling the demands of complex modern systems for top performance at high data transmission rates. With these pseudo coaxial configurations, the grounding contacts are routed around the signal contacts. This makes it possible to create a pseudo coaxial design, using contacts otherwise used only for grounding.

The 10 row ERmet series is available both as female connector and male connector. The female connector has the same proven dual contact design first used with the ERmet 7 row connectors in compliance with IEC 61076-4-101. This special design principle ensures extremely good RF characteristics such as low noise, controlled impedance, short delay times, minimal skew and high reliability (Figure 2).

Eight rows of the new connector range are used for signal contacts, the two outside rows of contacts, for shielding. The integrated shielding offers 2,0 mm connectors in compliance with IEC 61076-4-101's significant advantages (Figure 3).

In the case of the ERmet female connector, the shielding frame is a step deeper in the insulator and securely attached with hooks in the insulating chamber (Figure 4). This design principle prevents the shielding plate from being bent or damaged when the male connector is inserted.

Type D: Fitted with 220 pin (176 signal and 44 shielded ground contacts) arranged in a 50 mm housing with an integrated multifunctional block for coding and adjustment purposes, or for retrofitting with an additional pin for ESD protection or a high-current contact.

Type E: Fitted with 250 pins (200 signal contacts) arranged in a 50 mm long housing.

Type F: Fitted 110 pins (88 signal contacts and 22 shielded ground contacts).

All ERmet 2,0 mm connectors are designed for solderless pressfit technology and offer the recognised processing and quality advantages. Thanks to their elastic pressfit zone, a gastight, corrosion-proof and mechanically stable (against shock and vibration) connection is created.

These 2,0 mm grid metric connectors, which include the Compact PCI and VME 64 extensions, are the preferred solution for telecommunications and networking applications, such as switching equipment, computer technology, modems, high-speed computers, machine controllers, medical imaging systems, and other types of electronic equipment and instrumentation that require high electrical specifications and contact densities (Figure 5). Over the years 2,0 mm connectors have demonstrated their superiority in complex applications, leading to continuous expansion of their range of applications. The recently introduced generation of metric connectors with 10 rows of signal contacts (250 pins) on a 50 mm connector, designed for pressfit technology, continues to meet the growing demand for higher contact density/s.
