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.
