High-Density Edge Card Sports Ultra-Fine Pitch

Samtec unveils the MEC5, what it is calling the industry’s first 0.5-mm pitch edge card socket with justification beam. Reportedly, this design meets the demands for decreased size and increased speeds, while also optimizing cost. The socket’s justification beam is designed to shift the card into proper alignment with the contacts. This allows for standard board tolerance on cards that would typically not work with ultra-fine pitch connectors. This optimizes manufacturing costs with a 30-50% PCB cost savings and a high yield for standard cards.


Available in both vertical (MEC5-DV) and right-angle (MEC5-RA), this socket features up to 300 total I/Os for high-density applications. To meet demands for speed, the vertical socket is designed for 28 Gbps NRZ/56 Gbps PAM4 performance. Both orientations are designed to handle PCIe Gen 4 signaling.
