Product details

MTA-156 IDC Receptacle, 4 Positions, 0.156" Pitch

The 3-644860-4: The 0.156" (3.96mm) pitch gives enough spacing for 18 AWG wire without crowding the IDC slot, making it a standard choice for internal power and signal harnesses in appliances, HVAC controls, and vending equipment.

IDC termination accepts 18 AWG discrete wire or ribbon cable — the contact pierces the insulation and makes gas-tight connection without stripping or crimping. This speeds harness assembly in medium-to-high volume production. The closed-end housing prevents wire strands from exiting the back of the connector, which is useful when the harness routes into a confined space.

The latch is audible and tactile on full engagement, giving field confidence that the pair is locked. For free-hanging applications, the ramp resists un-mating from cable tug or vibration better than a friction-only detent.
