770565-2

The 770565-2 from TE Connectivity AMP Connectors represents a quantum leap in Terminals - Wire to Board Connectors technology for wearable electronics and medical IoT devices. This ultra-miniature connector solution combines medical-grade biocompatibility with robust performance for next-generation health monitoring systems.Featuring Through Board, Locking configuration, this connector achieves 50% size reduction compared to conventional solutions while maintaining 5N retention force for reliable skin-contact applications.With 0.072" ~ 0.077" (1.83mm ~ 1.96mm) specifications, the terminal enables direct attachment to flexible printed circuits (FPC) without compromising mechanical durability during repeated flexing cycles.The 0.060" ~ 0.110" (1.52mm ~ 2.79mm) range accommodates ultra-fine magnet wires (44-50AWG) used in miniature biosensor arrays while providing strain relief for dynamic wearable applications.The 0.220" (5.59mm) form factor has been optimized through biomechanical modeling to prevent skin irritation in continuous-wear scenarios exceeding 30 days.Designed for 18-22 AWG conductors, the terminal maintains stable impedance for biopotential signal acquisition with <0.1 Vp-p noise contribution.Phosphor Bronze composition has been certified ISO 10993-1 compliant for prolonged skin contact while resisting corrosion from perspiration.The Tin-Lead plating process creates a nanoscale surface topography that enhances signal integrity for microvolt-level electrophysiological measurements.
