MAF type Inter-Connector consists of multiple rows of metal fibers arranged symmetrically in a sheet of silicone rubber. This type is the thinnest of metal connectors. Various shapes are available because of punch-out manufacturing method applied. MAF type connectors are used for extensive applications including assembly or inspection device.
