The Molex MX150 0477256030 is a 12-position, dual-row plug housing from the MX150 47725 series. It accepts male blade contacts terminated via crimp and mounts to a panel through the locking ramp feature. The 3.50 mm pitch is the standard for this sealed, industrial-grade connector family, sized for wire-to-wire and wire-to-board power and signal interconnects in environments that demand vibration resistance and a wide thermal range. The Terminal Position Lock (TPA) provides a secondary retention mechanism that confirms each crimped terminal is fully seated before the connector is mated, reducing the risk of a pin push-out in a harness that sees field vibration.
Contacts Not Included — What That Means for Your BOM
This is a housing-only listing. The crimp terminals must be ordered separately — a common sourcing miss that stalls a harness build. The MX150 series uses male blade terminals (typically Molex 33000 series) that are crimped onto the wire and then inserted into the housing cavities. The TPA feature then locks them in place. Without the terminals, the housing is an empty shell. The 12-position count and dual-row layout match the standard MX150 receptacle housings of the same circuit count and pitch. The locking ramp provides an audible click when fully mated, and the panel-mount ears allow the plug to be fixed to a bulkhead or bracket, keeping the wire harness serviceable at the panel face.
