The Molex MX150 1600783023 is an 8-circuit sealed receptacle from the MX150 160078 series, built for wire-to-wire or wire-to-board harness connections in environments where moisture, vibration, and temperature swings are the norm.
What the Sealed Rating Means for Your Harness
The 'Sealed' feature on this MX150 receptacle means the housing is designed to accept silicone or rubber interfacial seals (typically in the mating half and at the wire-entry grommet) that keep water, dust, and splash out of the contact area.
This is a female receptacle — it mates with the corresponding MX150 male header or plug housing (same 0.138" pitch, same 8-circuit, 2-row layout). No soldering or PCB mounting — this is a pure in-line harness connector.
