This housing is explicitly marked as Sealed, meaning the interface between the housing and the mating header, as well as the wire-entry points, are designed to keep out moisture, dust, and other contaminants. ## Mating Connector and Terminal Fit This receptacle housing mates with the corresponding MXP120 34900 series male header (plug housing) of the same 4-circuit, 4.00 mm pitch configuration. The female blade socket terminals used with this housing are part of the MXP120 terminal family; the specific crimp terminal part number depends on the wire gauge (typically 20-22 AWG for the MXP120 system) and plating requirement (tin or gold). The CPA feature on the housing works with a matching feature on the header to ensure the connector is fully seated and locked. It is ROHS3 compliant.","metaTitle":"Molex MXP120 0349004121, 4-Pos Receptacle Housing, 4.00mm","metaDescription":"Molex 0349004121 MXP120 4-position receptacle housing, 4.00mm pitch, sealed with CPA.
