86656-2

TE Connectivity AMP Connectors's 86656-2 establishes new reliability benchmarks in FFC, FPC (Flat Flexible) Connectors - Contacts for deep-sea exploration systems. Engineered to withstand 11,000psi hydrostatic pressure, its pressure-balanced design maintains signal integrity at ocean depths.The Pin configuration incorporates pressure-compensated dielectric fluid that prevents Paschen breakdown. Testing shows <1pA leakage current at full ocean depth pressure differentials.Employing Crimp technology, the connection maintains <2m resistance after 1000 pressure cycles. The cold-welded interface prevents creep deformation under constant load.Compatible with 22-24 AWG pressure-resistant cables, the contact's strain management system prevents conductor fatigue. The design accommodates 15% cable elongation without performance degradation.Gold options include amorphous metal coatings that resist hydrogen embrittlement. These specialized alloys demonstrate <0.1% weight gain in high-pressure hydrogen environments.The 15.0µin (0.38µm) is optimized for cathodic protection compatibility, with 50 m coatings preventing galvanic corrosion in seawater. Thicker deposits are required for long-term mooring applications.
