Product details

4-Position Header Housing for H-DAC 64 Harnesses

The Molex 0310681040 is a 4-circuit, single-row header housing from the H-DAC 64 31068 series. That TPA feature is the main reason to reach for this housing over a plain latch version in a harness that sees movement.

Mating and Contact Fit

The 0310681040 mates with the matching H-DAC 64 receptacle housing of the same 4-circuit count and 2.54mm pitch — the female half that accepts the female crimp terminals. Order the terminals separately — they are not included in the bag.
