66579-4

The 66579-4 from TE Connectivity AMP Connectors delivers military-grade performance in Backplane Connectors - Contacts for defense applications. Compliant with MIL-DTL-38999 Series III specifications, this circular connector provides secure, EMP-hardened connections for radar systems and battlefield communication equipment.Supporting Signal signal transmission, the connector features triple-redundant shielding for HEMP protection. Electromagnetic pulse attenuation exceeds 100dB from 10kHz to 10GHz as verified by independent testing.The Pin design incorporates hermetic sealing technology for submarine applications. Each contact is individually tested for helium leakage rates below 1 10^-9 atm cc/sec.Utilizing Crimp techniques qualified to MIL-STD-202G, the connections withstand mechanical shock up to 100G. Special tooling ensures consistent termination quality in field repair scenarios.Certified for 16-18 AWG military-spec wiring, the connector backshell provides 360 cable shielding. The design prevents cable rotation while maintaining bend radius requirements for armored cables.The Gold plating composition includes rare earth elements for enhanced durability. Accelerated life testing demonstrates contact resistance stability through 500 mating cycles in sandy environments.The 30.0µin (0.76µm) specification meets MIL-G-45204 Class 2 requirements. X-ray fluorescence testing verifies coating thickness uniformity across all contacts in the assembly.
