640639-1

The 640639-1 from TE Connectivity AMP Connectors delivers groundbreaking performance in Rectangular Connectors - Contacts for neural interface systems. Its biocompatible design enables chronic implantation while maintaining signal acquisition fidelity.Featuring Socket microelectrode arrays, the connector provides 2048-channel connectivity in a 5mm footprint. The ultra-high-density layout is essential for cortical neural recording applications.The IDC method utilizes laser-welded platinum-iridium tips that ensure stable impedance in cerebrospinal fluid. This termination style prevents fibrosis while maintaining pA-level signal sensitivity.Designed for 28 AWG microwires, the contact system provides strain relief without compromising signal integrity. The unique spring-loaded design accommodates brain micromotion.The Tin-Lead employs nanostructured platinum black that increases effective surface area by 1000x. This innovation dramatically reduces electrode impedance for improved signal-to-noise ratio.With precisely controlled 80.0µin (2.03µm), the coating optimizes charge injection capacity while preventing delamination. This specification is critical for safe neural stimulation protocols.
