The TE Connectivity 640581-1 is a 6-position plug housing from the Universal MATE-N-LOK series, designed for free-hanging inline wire-to-wire or wire-to-board harness applications. The single-row layout and latch-lock fastening make it a practical choice for power and signal interconnects in appliances, automotive interiors, and industrial control panels where a secure, vibration-resistant mate is needed without tools. The housing accepts either male or female crimp contacts, giving the harness builder flexibility to assign pin/socket gender per the circuit requirement.
The latch lock engages with an audible click, holding the mated pair together under vibration without requiring a secondary locking clip. White colour aids visual identification in a multi-connector harness. Contacts are not included — you order the crimp terminals separately (male and female pins from the Universal MATE-N-LOK terminal family). The housing is a shell; the current rating and wire range are determined by the terminal you load. Plan the terminal part numbers into your BOM as a separate line item.
Mating and Termination
This plug housing mates with the corresponding Universal MATE-N-LOK receptacle housing (same series, same position count). The latch lock on the plug side snaps into the receptacle's locking window. Termination is crimp-style — strip, crimp the terminal onto the wire, insert into the housing cavity until the lance locks. No soldering, no special tooling beyond a standard crimp press and the correct terminal applicator.
