14-Position IDC Receptacle for MTA-100 Harnesses
The TE Connectivity 4-641240-4 is a 14-position receptacle from the MTA-100 series, designed for mass-termination of discrete or ribbon cable using IDC (insulation displacement) contacts. The closed-end housing prevents the header pins from pushing through the back, a common failure when an open-end IDC connector is mated to a longer pin header.
Locking Ramp and Right-Angle Wire Exit
The locking ramp fastening type latches the receptacle to the mating header — it holds the pair together under cable tug or vibration, which matters in an industrial cabinet or moving assembly where an unlamped connector would walk off. The free-hanging right-angle mounting means the cable exits perpendicular to the connector face, so the harness can run flat along a panel or inside a shallow enclosure without a sharp bend. The green housing is a visual line identifier — it distinguishes this 14-position receptacle from other MTA-100 color variants during build or rework.
IDC Termination for 28 AWG
Termination is IDC — the 28 AWG wire is pressed into insulation-displacement slots in the contact, so no separate crimp terminal is needed. This saves a crimp station and a part number on the BOM, but the trade-off is that the wire gauge is fixed at 28 AWG; the IDC slot geometry won't grip a thinner or thicker wire reliably. The connector accepts discrete or ribbon cable, so it works for both point-to-point wiring and multi-conductor ribbon harnesses.
