20-Position Plug Housing for Wire-to-Board Harnesses
The TE Connectivity 172047-2 is a 20-position, 2-row plug housing from the standard 3.00 mm pitch family, designed for free-hanging (in-line) wire-to-board or wire-to-wire applications.
The 20 positions in two rows give a 10-per-row layout — a common count for multi-conductor harnesses feeding a single board connector.
Contacts Not Included — Plan Your BOM
The listing note 'Contacts Not Included' is the single most important procurement detail on this page. Without the contacts in the BOM, the housing is dead stock on the shelf. Order both halves of the mating pair: the plug housing plus the header or receptacle it mates with, plus the loose contacts.
Free-Hanging Mounting and Crimp Termination
Free-hanging (in-line) mounting means this housing is not board-mounted — it terminates a cable harness that plugs into a board-mounted header or a panel-mount receptacle. The crimp termination style requires a dedicated crimp tool for the matching socket contacts; the housing itself has no solder or IDC contacts. This is a field-serviceable design: replace a damaged contact by re-crimping a new terminal into the same cavity.
