It carries a 0.138\" (3.50mm) pitch — wide enough to handle moderate current without forcing a dense board layout, and common in power-distribution harnesses inside industrial control cabinets or automotive junction boxes. The latch lock on the housing gives an audible click when mated, holding the pair together under vibration without relying on a secondary clip. It is a free-hanging (in-line) receptacle — no board-mount footprint — so it terminates a cable assembly that plugs into a board-mounted header. ## Contacts Not Included — What You Need to Order Separately The 1722561002 ships as an empty housing only. The female socket crimp terminals must be ordered separately — the series uses the Ultra-Fit crimp contact, typically Molex p/n 172253 series for the female side. The contact termination is crimp, so you need the correct wire gauge (check the terminal datasheet for the range) and a compatible crimp tool. No contacts are included in the bag. ## Mating and Termination Checklist Mates with a board-mounted Ultra-Fit header of the same 0.138\" (3.50mm) pitch and 2 circuits. The latch lock on the receptacle engages the header's locking ramp. Termination is crimp — strip the wire, insert the crimped terminal into the rear of the housing until the retention barb seats, and tug-test to confirm. The single-row layout keeps the assembly narrow, useful where harness space is tight.","metaTitle":"Molex Ultra-Fit 1722561002 Receptacle, 2 Pos, 3.50mm","metaDescription":"Molex Ultra-Fit 1722561002 2-position receptacle, 0.138\" (3.50mm) pitch, crimp termination, latch lock.
