The Molex 0348406410 is a 12-position, dual-row plug from the MX150 34840 series — a sealed, twist-lock connector family built for underhood automotive and industrial harnesses where water ingress and vibration are the main failure modes. The 3.50 mm pitch and 6.00 mm row spacing give it a chunky footprint that handles the creepage needed for the IP67K seal.
The IP67K rating means this plug seals against dust immersion and high-pressure, high-temperature washdown spray — the K suffix adds the steam-clean test that standard IP67 skips. That seal lives in the twist-latch fastening: you rotate the latch ring to compress the gasket, and the latch holds the pair mated under the kind of vibration that shakes a standard latch loose. The twist-lock also gives a tactile confirmation of full mate — you feel it seat.
Contacts Are Ordered Separately — Don't Get Caught Short
Contacts are not included. This plug accepts male blade crimp terminals ordered separately.
The panel-mount, bulkhead mounting style means the plug can be the fixed side on a bulkhead pass-through, with the receptacle on the harness side. Confirm the receptacle part number from the same series before committing the BOM.
