It accepts male blade contacts terminated via crimp — the contacts are ordered separately.
The 'Sealed' feature means the connector body is designed to mate with a corresponding sealed receptacle, forming a weatherproof joint. This is not an IP-rated standalone claim, but the MX150 family is widely used in automotive harnesses where splash and dust ingress must be blocked.
This plug ships as a housing only — the male blade crimp terminals must be sourced separately. The MX150 series uses specific terminals (typically Molex 34900 or 34901 series for wire sizes around 18-22 AWG, though the exact wire range is not listed here). For a production BOM, add the terminal part number and confirm the wire gauge matches the crimp specification before committing the build.
