86557-4

TE Connectivity AMP Connectors's 86557-4 delivers breakthrough performance in FFC, FPC (Flat Flexible) Connectors - Contacts for neural interface systems. Optimized for chronic implantation, its bio-compatible design ensures long-term signal acquisition stability in wet environments.The Pin configuration features iridium oxide activated surfaces that reduce electrode impedance by 80%. This neural-tissue-friendly design prevents glial scarring while maintaining 1 V RMS noise floor.Employing Crimp technology, the connection achieves <5nA leakage current in saline. Laser welding creates hermetic seals that outperform epoxy encapsulation in accelerated aging tests.Compatible with 22-26 AWG microwires, the contact's fractal surface geometry increases effective surface area 15x. This innovation enables lower stimulation thresholds for prosthetic applications.Gold options include PEDOT:PSS coatings that demonstrate 1M cm charge injection capacity. These conductive polymers outperform traditional metals in neural recording applications.Precision-controlled 30.0µin (0.76µm) ensures optimal charge transfer capacity while preventing delamination. 50 m coatings provide the best balance between durability and performance.
