Samtec has expanded its line of Edge Rate board-to-board connectors to include a higher-density mated set that's half the width of its previous designs and offers a lower-profile 5 mm mated height (ERF6 & ERM6 Series). ERF6 and ERM6 Series Edge Rate connectors support 56 Gbps PAM4 high-speed mezzanine applications for industrial, embedded vision, instrumentation and monitoring, drones, and robotics.
The connectors have two rows of pins on a narrow body width of 2.5 mm. Body length is 11 to 43 mm with a 0.635 mm centerline. Available positions for each row are 10, 20, 30, 40, 50 or 60.
If pull and shear force are a concern, weld tabs are available within the standard part number configuration.
Despite its low profile, 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. 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).
Samtec’s Edge Rate family of products uses a contact system that extends cycle life, increases durability, and lowers insertion and withdrawal forces. 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.
