Edge Rate® High-Speed Contact System

Samtec's ERM8 and ERF8 series contact systems feature incredible design flexibility and are designed for high speeds and high-cycle applications

Image of Samtec's Edge Rate® Contact High-speed 0.8 mm pitch strips feature Samtec’s Edge Rate® contact system and are designed for high speeds up to 56 Gbps PAM4, as well as high-cycle applications. The smooth broad-milled contact surface increases wear life, while the minimized parallel surface area reduces broadside coupling and crosstalk. This also lowers insertion and withdrawal forces, allowing the connectors to be zippered when unmating. An extended 1.5 mm contact wipe ensures a reliable connection. The ERM8 and ERF8 series feature incredible design flexibility including 10 to 200 total positions, 7 mm to 18 mm stack heights, differential pairs, hot swap option, and a choice of orientation – vertical, right-angle, or edge mount. Optional rugged features are available, such as metal latching for increased retention force and extended guide posts with or without shielding. Many high-speed protocols are supported, such as Ethernet and PCI Express®.

Features
  • Choice of 0.50 mm, 0.635 mm, or 0.80 mm pitch
  • Edge Rate contacts optimized for signal integrity performance
  • Up to 1.5 mm contact wipe for a reliable connection
  • 10 to 200 positions
  • Rugged latching, locking, and 360° shielding available
