Right-angle 10-position unshrouded header for board-to-wire
The 1-640453-0 is a 10-position, single-row unshrouded header from the MTA-100 series, with a 0.100" (2.54mm) pitch — the standard footprint for many IDC and crimp-to-wire connectors. The right-angle orientation places the pins parallel to the PCB, saving vertical space in enclosures where a straight header would conflict with a cover or adjacent board.
Tin-plated contacts and UL94 V-0 housing
Both the mating and post finishes are tin, rated for moderate mating cycles — expect a few dozen insertions before contact wear becomes a concern. The thermoplastic housing carries a UL94 V-0 flammability rating, meeting the fire-safety requirement for equipment inside an enclosure.
