EC.8: High-speed direct-connect system
Unlike traditional connectors, card edge connectors minimize a wide variety of obstacles such as changes in direction, reflections, and changes in cross-section, which ensures clear signal transmission.

Tolerances
Permitted radial misalignment
Tolerances EC.8 card edge connector tolerate an offset of 0.6 mm along the longitudinal axis and 0.7 mm along the transverse axis during mating.
Permitted Angular Offset Tolerances
With EC.8 card edge connectors, the daughtercard can be inserted into the EC.8 at an angle of up to 5° along both the longitudinal and transverse axes.
EC.8 SMT card edge connector with a 0.8 mm pitch
Thanks to its design, our EC.8 is already a high-speed pro, offering data transfer rates of up to 28 Gbit/s. It’s just right for modern Industry 4.0 applications and related fields such as the Internet of Things, cloud computing, and edge computing.
In addition to its high data rate, the direct connector (card edge connector) offers the following advantages:
Direct contact with a printed circuit board saves space and resources, as material costs and the assembly effort for the Male are completely eliminated. The technical advantage stems from the reduction in resistance and interference that can affect a signal.
To provide the right card edge connector for every application, our EC.8 is available in the industry-proven 0.8 mm pitch with a range of 20 to 200 signal pins, selectable in increments of 20.
The EC.8 family has undergone an extensive testing program, demonstrating proper function after, among other things, climate storage, shock and vibration exposure, and even after 500 mating cycles.

FAQ: Questions and Answers About EC.8 SMT-Leiterplattensteckverbindern
How can EC.8 direct-plug connectors be installed?
The direct-plug connectors are processed using Surface Mount Technology (SMT). Soldering is performed directly onto the printed circuit board. For a number of positions ranging from 20 to 140,
products are shipped in industry-standard tape and reel-Verpackung; this enables fully automated processing via pick-and-place.
Connectors with a number of positions from 160 to 200 are packaged in a tray by default; tape and reel-Verpackung is also available upon request. However, this uses a wider tape, which is less common.
According to which specification or layout must the plug-in card be manufactured?
Please refer to the drawing below for the chamfering and dimensions of the printed circuit board. We recommend “hard gold” for the gold pads. Please refer to the product drawing for further details.
Why should a direct-card edge connector system be used?
High data rates can be achieved using direct-plug systems. Compared to two-part connector systems, these eliminate the negative effects of the second connector on the signal. This is primarily due to the reduced number of contact points, fewer changes in the conductor’s cross-section, and the resulting fewer changes in the signal’s direction.
This allows for high performance even with a small footprint. Additionally, the contact resistance is reduced compared to two-part connector systems, resulting in increased current-carrying capacity.
Is the EC.8 connector system compatible with common daughter card specifications?
The EC.8 connector system supports daughtercards with a thickness of 1.60 mm. For connectors with 80 or more contacts, a spacer is also integrated to prevent incorrect insertion. This spacer can be omitted in the 60-pin version if desired.
The EC.8 connector-System complies with current market standards and is compatible with widely used boards.
For which applications are EC.8 direct connectors (card edge connector) used?
Due to their versatility, EC.8 direct connectors (card edge connector) are used in a wide variety of applications across numerous industries. In the fields of automation technology and IoT devices, for example, they benefit from their small pitch and high data rates.
What misalignment do EC.8 direct connectors (card edge connector) tolerate when inserting the daughter card (daughtercard)?
An angular offset (angular misalignment) of up to 5° is tolerated in both the longitudinal and transverse directions.
An offset of 0.7 mm perpendicular to and 0.6 mm parallel to the longitudinal axis of the connector is tolerated.
What data rates can be transmitted?
The data transfer rate is 28 Gbit/s. The following diagram shows the insertion loss (insertion loss) versus frequency.
What types of power can be transmitted?
A 140-pin connector transmits up to 3.2 A at an ambient temperature of 20°C. For more detailed information, please contact us at sales@eptusa.com
Are EC.8 connector UL-recognized components?
Yes, EC.8 connector from ept are UL-recognized components in the U.S. and Canada.
Are the EC.8 connector RoHS-compliant?
RoHS (Restriction of the Use of Certain Hazardous Substances) is the directive restricting the use of certain hazardous substances in electrical and electronic equipment.
We confirm that EC.8 connector from ept are compliant with RoHS Directive 2011/65/EU, as per the RoHS certificate. For more information, see RoHS & REACH
