EC.8: Direct connector system with high speed at its core

Highspeed mit Pfeile.png

The edge card connector principle enables data transmission rates of up to 28 Gbps.

Edge card connectors have shorter transfer pathways and fewer cross section changes which enhances the signal. A direct contact reduces the resistance and influence on the signal. This positively affects the current capacity and data transfer properties. A lower resistance defines the edge card connection when compared to a similar connector pair.

Edge card connector versus connector pair

The edge card connector enables direct contacting of the PCB without a corresponding mating connector. In comparison to a conventional connector pair, there are fewer contact points and transitions resulting in a positive effect on current carrying capacity and data transmission properties.

"Are you looking to achieve maximum power without wasting a lot of space? How about an edge card connector built specifically for HighSpeed applications?

The core design of the EC.8 embodies HighSpeed performance, offering transfer rates of up to 28 Gbps. An ideal connector for Industry 4.0 applications such as IoT and cloud computing.

Besides fast data transfer rates, this edge card connector also offers the following advantages: Connecting a PCB directly to the EC.8 saves space and resources, because of the omitted material and fitting costs for male multi-pin connectors. One technical advantage originates from the reduction of resistances and influences that can have an effect on the signal.
Finding the right edge card connector for you application is easy with our EC.8 and its industry-proven 0.8 mm pitch, available in variations of 20 to 200 pins, in steps of 20.

The EC.8 family underwent comprehensive testing, in which proper operation during thermal cycles, exposure to shock and vibration, and even after 500 mating cycles, was demonstrated.
Want to learn more? Feel free to ask us about the EC.8 HighSpeed report and S-parameters and discover all of its advantages for yourself."

FAQ: Questions and answers about EC.8 direct connectors

How can EC.8 direct connectors be processed?Which specification/layout should be applied when manufacturing the plug-in card?Why should a direct connector system be used?Is the EC.8 connector system compatible with the current daughter card specifications?What applications are EC.8 direct connectors used for?What offset do EC.8 direct connectors tolerate when inserting the daughter card?What data rates can be transmitted?What currents can be transmitted?Are EC.8 connectors UL recognized components?Are the EC.8 connectors RoHS compliant?

How can EC.8 direct connectors be processed?

The direct connectors are processed using surface mount technology (SMT). The soldering is done directly on the printed circuit board.
Pin counts 20 to 140 are supplied in market-compliant tape and reel packaging; this enables fully automatic processing via pick-and-place.
Pin counts 160 to 200 are packed in the tray as standard; tape and reel packaging is also available on request. However, this also uses a wider strap, which is less common.

Which specification/layout should be applied when manufacturing the plug-in card?

Please see the diagram below for details on the chamfering and dimensions of the circuit board. We recommend hard gold for the gold pads. Please refer to the product diagram for further details.

Why should a direct connector system be used?

High data communication rates can be realized using direct connector systems. In comparison to two-part connector systems, the negative effects of the second connector on the signal no longer apply. This is primarily due to the reduced number of contact points, less cross section changes in the conductor and associated fewer direction changes by the signal.
Consequently a high performance can also be attained with a small footprint. The contact resistance is also reduced in comparison to two-part connector systems, this resulting in increased current carrying capacity.

Is the EC.8 connector system compatible with the current daughter card specifications?

The EC.8 connector system supports daughter card systems with a thickness of 1.60 mm. For more than 80 pins, keying prevents incorrect connection. This is optional for the 60 pin version.
The EC.8 connector system corresponds to the current market standard and is compatible with the processed boards.

What applications are EC.8 direct connectors used for?

Thanks to their versatility, EC.8 direct connectors are used for diverse applications in numerous sectors. In the field of automation technology and IoT devices, they typically benefit from their small grid and high data transmission rates.

What offset do EC.8 direct connectors tolerate when inserting the daughter card?

An angular offset of up to 5° can be tolerated in a longitudinal and transverse direction.
An offset of 7 mm vertically and 6 mm parallel to the longitudinal axis of the connector can be tolerated.
