Edge connectors offer up to 150 I/O


General DPN

Samtec has expanded its Edge Rate product line with the addition of .8mm pitch Right Angle and Edge Mount connector strips for perpendicular and co-planar applications. The systems feature contacts that are designed to minimize broadside coupling, decrease crosstalk between adjacent contacts, and offer low insertion/withdrawal forces and high cycles.

Edge Rate Right Angle (EFM8-RA/ERF8-RA) and Edge Mount (ERM8-EM/ERF8-EM Series) terminals and sockets offer up to 150 I/Os in single-ended or differential pair configurations with a standard choice of 10 to 75 positions per row (dependant on orientation). The strips are said to be robust when zippered during unmating and feature an optional rugged metal latching system. 

The new Right Angle and Edge Mount connectors may also mate with the Edge Rate board stacking system (ERM8/ERF8 Series). Cable mates for the strips include 34 AWG EyeSpeed Micro Coax High Speed (ERCD Series) and Signal Integrity-optimizing “Direct-to-Lead” (ERCDA Series) Cable Assemblies, 30 AWG EyeSpeed Twinax High Speed Cable Assemblies (ERDP Series), and High Speed Flex Data Links with Edge Rate contacts (ERDL2 Series).
