Product Details Supplier Info More products

Four ruggedised connectors from TE Connectivity designed for military, aerospace and space applications, are now available. TE’s Mezalok, MULTIGIG RT 2-R, CeeLok FAS-T and Fortis Zd series high performance interconnects provide high-speed, reliable and lightweight, robust solutions in harsh environments.  

TE’s Mezalok surface-mount connectors are designed for stacking or mezzanine applications and ensure high-speed 5GHz data rates in the most adverse environmental conditions, while TE’s MULTIGIG RT 2-R is a ruggedised, lightweight high speed board-to-board modular interconnect system.

CeeLok FAS-T is one of the smallest, most rugged 10GB Ethernet, field-terminable I/O connector available for the aerospace, defence and marine market, saving both space and weight due to its size 8 shell. TE’s Fortis Zd is a modular backplane connector system which combines a high-performance mil/aero specification with commercial technologies in a user-configurable platform.
