Introducing TE Connectivity’s (TE) new CeeLok FAS-X connector series, a high speed solution for 10 Gbps data delivery using rugged, mil-spec components. Optimized for high speed signaling, CeeLok FAS-X connectors offer performance beyond what is obtainable with popular pinouts used in standard D38999 connectors. This new product offering surpasses the performance of RJ45 in D38999 connectors with its smaller size (shell size 11 vs shell size 19) and intentional use of standard M39029 contacts suitable for harsh environments. Designed to maintain highly matched 100-ohm impedance and superior signal integrity, CeeLok FAS-X connectors provide a performance margin that enables effective signal delivery in rugged environments.
