Product details

Sealed 4-Position Housing for Inline Harness Builds

The 4.00 mm pitch provides enough spacing for power and signal circuits in a sealed environment, while the integrated Connector Position Assurance (CPA) latch locks the mating pair together, preventing accidental disconnect under vibration. 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.
