New Albany, Ind.-Samtec has introduced a high-speed edge card socket that accepts two PCB cards. The connector accommodates two .062" (1.6mm) thick PCB cards. This .8mm (.0315") pitch system, in a right angled configuration, allows "dual stacked" cards at an industry standard 7mm (.276") spacing between cards.
The .8mm (.0315") pitch right angle Edge Rate Dual Stack Edge Card Socket (DSEC Series) is available with 30, 40 or 50 Edge Rate contacts per row. This rugged contact system is optimized for signal integrity and impedance control, high cycles, reduced broadside coupling, and low insertion/withdrawal force.
Lead-free solder charge terminations for easy board processing are standard with tin-lead solder charges available as an alternative option. Additional card spacings and an elevated single-card system are also available.
Pricing: $ .05 to $ .06 per pin in small production quantities.
