The 1-144546-0: It is a free-hanging, in-line connector body that accepts female socket contacts terminated via crimp — the contacts themselves are ordered separately. The housing is moulded from glass-filled PA66 (Nylon 6/6) in black, with a latch lock that gives a positive audible click when mated to the matching header.
The 5.00 mm pitch and 3 positions match a 3-circuit BOM line.
Contacts Are Not Included — What You Need to Order
The listing note says it plainly: contacts are not included with this housing. You order the 1-144546-0 shell and then source the matching female socket crimp terminals separately — typically the TE 144546-2 or equivalent MIC-series contact. The housing accepts the contacts after they are crimped onto the wire, then they lock into the cavity with a retention tang. If you are building a harness from scratch, make sure the BOM includes both the housing and the contacts plus the correct crimp tooling for the wire gauge you are running.
Mounting and Retention
This is a free-hanging (in-line) receptacle — no panel-mount flanges, no board-lock posts. It sits in the harness and mates to a header that is either board-mounted or another in-line plug. The latch lock on the housing snaps over the mating header's ramp and holds the pair together against vibration and cable tug. For field service, the latch is easy to depress with a thumb or small screwdriver to unmate the connector without prying on the housing walls.
