328 Series Product Description 75 Ohm 16-Position Gang Mate MCX System Winchester’s new 328 Series Gang Mate MCX Connector System is compliant with SMPTE 424M-2006 and features a 75 Ohm MCX Connector design optimized for use with Belden 179DT cable. Our new 328 Series Gang Mate MCX 75 Ohm Connector System was designed for cable-to-printed circuit board (PCB) applications and consists of 16-position vertical and right-angle PCB Connectors, and overmolded cable assemblies with 16-position male connectors. Users will benefit from the ease and time savings of mating and unmating a single connector versus an array of individual connectors. Designers will benefit from the PCB real estate savings, its low profile, and RF performance. Additional position sizes are available upon request. • Molded cable assembly connectors feature male jackscrews with 3-48UNC-2A threads to secure the connector to mating PCB connectors. • PCB connectors contain two alignment posts to provide guidance for the mating cable connector as well as polarization to prevent connectors from being mismated. • Right-angle PCB connectors are low profile and sit just 0.295” above the PCB surface and designed for applications with as low as 0.5” card slot pitch.
