2-Position IDC Receptacle at 0.100" Pitch
No crimp tool, no terminal inventory — just a simple press. The closed-end housing means the wire stops at the back wall, so insertion depth is self-limiting.
The 3-644038-2 mates with any 2-position MTA-100 header at 0.100" pitch — typically the unshrouded vertical or right-angle headers from the same series. There is no keying or polarisation beyond the latch geometry, so the 2-position count prevents a reverse mate by simple asymmetry of the header pin field.
