Product details

MTA-100 2-Position IDC Receptacle

The 0.100" (2.54mm) pitch matches the standard MTA-100 pin header footprint, and the single-row, closed-end housing accepts the full cable width without a secondary strain relief. The locking ramp on the housing snaps onto the mating header ramp for vibration-resistant retention — a positive-latch feel when fully seated.

Mating and Fit

Cable Termination

IDC termination means the 24 AWG wire is pressed into the slot, displacing insulation to make contact — no crimp tool, no terminal strip. The housing accepts discrete wires or ribbon cable, making it a flexible choice for both point-to-point wiring and mass-terminated ribbon harnesses. The closed end prevents the IDC slot from being exposed at the rear of the housing.
