Product details

1.25mm Pitch, 16-Circuit Free-Hanging Receptacle Housing

The 1.25mm pitch keeps the footprint compact — each circuit sits on 0.049" centers, which is the dimension that determines the header pin layout on the PCB. It's a single-row, free-hanging (in-line) housing, so it terminates a cable bundle that plugs into a right-angle or vertical header soldered to the board. The housing is molded in black PBT/polyester.

Contacts are not included. The housing accepts the contacts after crimping, and they lock into the cavity with an audible click.

Frequently asked questions

Does the Molex 2045321601 include contacts?

No. The 2045321601 is a receptacle housing only — contacts are not included. You must order the matching Micro-Lock PLUS female crimp terminals separately for the wire gauge you are using.

What is the pitch of the 2045321601?

The pitch is 1.25mm (0.049"). This is the center-to-center spacing between adjacent circuits, which determines the header pin footprint on the PCB.
