Flexible stacking solutions for mezzanine connections

TE's stacking connector portfolio includes free height, fine stack and fine mate connectors. These products provide various flexible stacking solutions for mezzanine (vertical, parallel stacking board-to-board) connections. This portfolio includes many centerline, stack height and application options.

16G 0.5mm Free Height COM Connectors

Designed to connect PCBs in a parallel stacking, mezzanine configuration with up to double the speed (16 GT/s) of most previous generation 0.5mm FH connectors. Our connectors feature a new contact design that provides best-in-class signal integrity performance and enables a 30% reduction in mating and unmating force to facilitate easier operation. With the same PCB footprint as all COM Express standard connectors, there is typically no need to change PCB layouts when making upgrades to your application. These connectors are compatible to PCIe Gen 4 applications, support 5mm and 8mm stacking heights, and include 220 and 440 position options.
