6-Circuit Sealed Plug Housing at 4.00 mm Pitch
The yellow colour of the housing is deliberate — it makes the connector easy to spot in a dense harness bundle during assembly or field service. The housing is moulded from a blend of Polyamide (Nylon) and Syndiotactic Polystyrene (SPS), glass-filled — the SPS component gives better dimensional stability at the high end of that temperature range than straight nylon would.
Sealed Construction and Mating
The sealed feature means this housing accepts an interface seal — typically a silicone gasket or individual wire seals — so the mated connector pair can be rated to an IP standard when used with the matching sealed header and proper crimp terminals. That is the primary difference between this 0348996111 and a standard unsealed MXP120 housing: if your harness runs through a washdown zone or a splash-prone area, this is the housing to specify. The latch lock works with the seal to keep the pair mated even when the cable is tugged at an angle.
The contacts are blade pin type and terminate via crimp. The MXP120 series uses Molex 34899-series crimp terminals — typically the 0348990111 or 0348990211 for wire gauges around 18-22 AWG, depending on the current requirement. The housing does not come with contacts; you order the terminals separately and crimp them onto the wire ends before inserting them into the housing cavities. The primary latch in each cavity holds the terminal, and the housing's secondary lock (TPA) can be added to confirm full terminal seating.
There is no official second-source cross-reference; the MXP120 series is a Molex proprietary platform, so the mating header and terminals should be sourced from the same manufacturer to guarantee seal compatibility and latch fit.
