Board-mount half for MTA-100 wire-to-board harness
The 2-641215-0: This 20-position vertical header is the board-side anchor for a single-row MTA-100 wire-to-board connection. In a field-service or test fixture where the connector sees dozens of cycles per year, that plating grade gives decades of reliable contact resistance.
The UL94 V-0 thermoplastic housing holds its mechanical properties across that range, so the connector can live inside an industrial cabinet or outdoor telecom enclosure without flame risk.
