4-position, 0.100" pitch, right-angle header
The 640455-4 is a 4-position, single-row header from the TE MTA-100 series, on 0.100" (2.54mm) pitch. The housing is shrouded on one wall, providing polarization and mechanical protection for the male pins during cable insertion.
This header mates with MTA-100 series IDC receptacles and crimp-style housings — the 0.100" pitch and square 0.025" pins are the standard interface for TE's MTA-100 wire-to-board system. The solder tails are 0.140" (3.56mm) long, tin-plated, and designed for wave-solder assembly through a 1.6mm-thick PCB.
