It carries a 4.20mm pitch between cavities, which gives enough spacing for 20-18 AWG power or signal circuits without crowding the crimp terminals. The housing uses a locking ramp for positive retention — it clicks home and stays there under vibration, which matters in industrial control cabinets or appliance harnesses where a half-mated connector drops a line.
The 1-640518-0 accepts female socket contacts terminated via crimp, sized for the 4.20mm pitch cavity of the MR series. The exact terminal part number is not specified in this listing — confirm the contact wire range and plating grade against your harness requirements before ordering.
The mating half is an MR series receptacle housing with the same 4.20mm pitch and locking ramp interface. The receptacle accepts male tab contacts and locks with the same ramp profile.
Yes, the 1-640518-0 carries a RoHS3 compliance status.
The note 'Contacts Not Included' means the housing ships as an empty shell — the crimp terminals must be ordered separately to populate the connector.
