TE Connectivity, PCB Connector Housing – Universal MATE-N-LOK


PCB Connector housings give its users a receptacle for electrical connectors, when mounted onto a PCB (printed circuit board). PCB connectors are used to link different printed circuit boards to one another, or to allow a cable to be connected to a PCB.

Our range of TE Connectivity, PCB Connector Housings form part of the Universal MATE-N-LOK series. A typical application for a connector housing is to provide a receptacle for connectors when they are mounted to a printed circuit board. These types of fittings are an essential component that offer protection for the connection it is housing.

Features and Benefits


• Made from flame retardant UL94V-2 or UL94V-0 nylon.
• Each connector housing feature snap-lock latches, which allows for a quick release and polarization. (resulting in accurate mating)
• Pin and socket contacts can be fitted in to any of the Universal MATE-N-LOK Connector Housings.
• For use with Universal MATE-N-LOCK contacts. (Other contacts in our PCB Connector Contacts range may be applicable)
• Free hanging or panel mount.
• Wire to wire or wire to board applications.
• Plug housing - 6.35 mm pitch.
