MTA-100 IDC Receptacle for Discrete or Ribbon Cable Harnesses
The 3-640442-4: Tin-plated contacts with 80.0µin (2.03 µm) thickness carry signal-level current for moderate-cycle harness applications.
The free-hanging, right-angle mounting orientation suits cable-to-board runs where the wire exits parallel to the PCB. The closed end acts as a wire stop, ensuring consistent insertion depth across all four positions.
Locking Ramp Retention in Vibration Environments
In a harness subject to machine vibration or frequent cable flex, this prevents the pair from backing out — a common failure mode with friction-only connectors. The blue housing colour aids visual identification during harness assembly and troubleshooting.
