MTA-100 6-Position IDC Receptacle
The TE Connectivity 3-640620-6 is a 6-position, single-row receptacle from the MTA-100 series, using a 0.100" (2.54mm) pitch. It terminates discrete or ribbon cable via IDC (insulation displacement) contacts — no wire stripping needed, just a simple press. A locking ramp on the housing holds the mating header in place under vibration, and the red color aids harness identification on the line.
The 0.100" (2.54mm) pitch is the standard MTA-100 spacing — it matches the common 0.100" ribbon cable and the footprint of the mating MTA-100 header. The 22 AWG wire gauge is the specific size the IDC contacts are designed for; using a different gauge risks poor gas-tight connection or contact damage. The locking ramp provides positive retention; you'll hear it click when fully seated, and it resists back-out from cable tug or vibration.
