Product details

MTA-100 IDC Receptacle, 4 Positions, 0.100" Pitch

The 3-643816-4: The green housing includes a closed end that acts as a cable stop, and the locking ramp provides positive retention against the header latch — no secondary hardware needed for vibration-prone harness runs.

Locking Ramp and Closed-End IDC Termination

The closed end stops the cable at a fixed insertion depth, so each conductor lands at the same position relative to the insulation-piercing contact — consistent electrical performance across all four circuits.

Tin Plating and Wire Gauge Fit

It is rated for the full current capacity of the 28 AWG wire the connector is designed for. Tin-to-tin contact with a header of the same finish is reliable for the service life of the harness; if the application requires frequent reconnection or operates in a corrosive atmosphere, a gold-plated MTA-100 variant would be the better choice.
