MTA-100 IDC Receptacle — What This Connector Is
The TE Connectivity 4-640443-3 is a 13-position MTA-100 receptacle with a 0.100" (2.54mm) pitch, designed for mass-termination of 28 AWG discrete or ribbon cable via IDC contacts. The green, closed-end housing carries tin-plated female sockets and uses a locking ramp for positive retention with the mating header.
Wiring and Termination — IDC Fit
The IDC termination accepts 28 AWG wire — either discrete strands or ribbon cable. The insulation displacement contacts pierce the wire insulation in a single press operation, which saves crimp time on multi-conductor harnesses. The closed-end feature means the back of the housing is sealed, preventing wire poke-through.
Pitch and Position Count — Board Layout Fit
At 0.100" (2.54mm) pitch, this 13-position receptacle matches the standard MTA-100 header footprint. The single-row layout keeps the board-edge width to about 1.3 inches.
