494033-3

TE Connectivity AMP Connectors's 494033-3 redefines reliability in the FFC, FPC (Flat Flexible) Connectors - Contacts segment, offering military-grade performance for aerospace and defense applications. Its ruggedized design withstands extreme environmental conditions while maintaining signal integrity.The Pin design incorporates hermetic sealing features when used with compatible housings. This configuration maintains gas-tight integrity up to 15psi differential pressure, essential for avionics systems.Optimized for Crimp applications, the contact achieves MIL-STD-1344 Method 3007 compliance. The crimp zone geometry prevents insulation damage even with thin-wall fluoropolymer wires.Compatible with 22-24 AWG wiring, the contact's material selection prevents stress relaxation at temperature extremes. Testing shows <5% contact force reduction after 1000 thermal cycles from -65 C to 150 C.Gold options are carefully selected for outgassing characteristics, with tin demonstrating <0.1% TML in NASA outgassing tests. The finish also affects the connector's passive intermodulation performance.The 15.0µin (0.38µm) is qualified to MIL-G-45204 Class 00 requirements. Thicker deposits are mandatory for applications involving sliding contact during vibration.
