6-Pin, 2.54mm Pitch, Shrouded Header with Friction Lock
The 2-644487-6: This is a 6-position, single-row, vertical through-hole header from the MTA-100 series, on 0.100" (2.54mm) pitch. It is a shrouded - 4 wall design, meaning the plastic shroud surrounds the pins on all four sides, protecting them during handling and mating, and guiding the mating housing into correct alignment. The board guide assists in alignment during PCB insertion.
Gold-Plated Mating Interface for Reliable Contact
This is a standard MTA-100 series part, widely available through the supply channel.
Mating Connector and Terminal Selection
This header mates with the MTA-100 receptacle housing (e.g., 3-644487-6 family). The matching crimp terminal is the TE 640441 series (22-26 AWG) or 640442 (18-22 AWG), depending on wire gauge. The overall contact length is 0.440" (11.18mm), with a mating length of 0.200" (5.08mm) and a post length of 0.140" (3.56mm). The insulation height is 0.410" (10.41mm). These dimensions define the PCB keep-out and the clearance needed for the mating housing.
