ERM5 & ERF5 Edge Rate® Rugged High-Speed Strips

Samtec ERM5 and ERF5 Edge Rate^® Rugged High-Speed Strips are 0.5mm pitch terminal and socket strips optimized for signal integrity performance. These Samtec strips feature a smooth broad milled contact surface for increased wear life. The ERM5 and ERF5 strips offer up to 150 positions with a stack height from 7mm to 12mm. These connectors are available in right-angle (socket-only) versions. The ERM5 rugged high-speed headers feature Edge Rate contacts for reduced broadside coupling. ERM5 headers and ERF5 sockets offer a 1mm nominal contact wipe.
