The 4.00 mm pitch gives enough spacing for power-class circuits without forcing an oversized connector footprint, and the latch lock provides an audible click that confirms full engagement under vibration. This is the male (tab) half of the MCON sealed connector system — it mates with the matching female receptacle housing, and the tab contacts are field-terminated via crimp, so the harness builder selects the wire gauge and terminal separately. ## Contacts Not Included — What You Need to Order The 1-1703498-3 is a housing only — contacts are not included. The note on the listing is explicit: you must source the matching MCON tab crimp terminals separately. For the harness builder, this means confirming the wire gauge range and terminal plating (gold vs tin) against the application's current and mating cycle requirements before committing the BOM line. The housing accepts the standard MCON tab contact, so the terminal part number depends on wire size and seal requirements. ## Sealed Construction and Latch Lock The housing is flagged as sealed, which means it is designed for environments where moisture, dust, or splash exposure is a concern — typical in automotive underhood, off-highway, or industrial washdown zones. The latch lock fastening type provides positive retention without relying on a secondary locking mechanism, though the MCON system often supports a connector position assurance (CPA) feature for additional vibration resistance. The single-row, 2-position layout keeps the connector compact, and the free-hanging (in-line) mounting style suits harness-to-harness or harness-to-device runs where a panel cutout is not available.","metaTitle":"TE MCON 1-1703498-3 Plug Housing, 2 Pos, 4.00mm, Sealed","metaDescription":"TE Connectivity MCON 1-1703498-3 sealed plug housing, 2 positions, 4.00mm pitch, single row, latch lock, -40°C to 125°C.
