Samtec Introduces 0.635 mm pitch, Slim Body Edge Rate® Connectors


Staff member
New Albany, IN: Samtec has expanded its successful line of Edge Rate® board-to-board connectors to include a higher density mated set that is half the width of previous designs and offers a lower-profile 5 mm mated height (ERF6 & ERM6 Series). ERF6 & ERM6 Series Edge Rate® connectors support 56 Gbps PAM4 high-speed, rugged mezzanine applications for industrial, embedded vision, instrumentation and monitoring, drones, and robotics.

The state-of-the-art 70,000 square foot facility
Small & Rugged

ERF6 & ERM6 have two rows of pins while maintaining an extremely narrow body width of 2.5 mm. Body length is 11 mm to 42.8 mm with a 0.635 mm centerline. Available positions for each row are 10, 20, 30, 40, 50 or 60. This makes customization of products easy while still allowing for quick delivery.

If pull and shear force are a concern, weld tabs are available within the standard part number configuration.

Despite its very low profile of 5 mm, the connectors still allow 0.90 mm of nominal contact wipe for a reliable connection.

To ensure connectors are consistently aligned properly, polarizing features are molded into the connector body. As represented in the Product Spec Sheet, ERF6 & ERM6 products allow for angular and linear misalignment.

To further secure the two mating mezzanine cards, board stacking standoffs are available through Samtec (search for Samtec’s SureWare™ brand).

Contact System

Samtec’s Edge Rate® family of products use a unique contact system that extends cycle life, increases durability, and lowers insertion and withdrawal forces. It also has superior electrical performance compared to traditional stamped contacts. These benefits are achieved by using the flat smooth-milled side of the contact for the mating surface, instead of the cut-edge which can have rough microscopic edges and burrs. The narrow edge of the contacts are aligned within the connector body to reduce broadside coupling and crosstalk. The contact tail uses standard surface mount J leads for ease of processing onto the printed circuit board.
