Micro-D PCB - .050 Contact Spacing MDM-PCB MDM-PCB connectors are designed for use with flex circuitry, flat cable and printed circuit boards or multi-layer boards. They use the standard MDM metal shell and provide high density and high reliability in board-to-board, board-to-cable and cable-to-cable applications. MDM-PCB connectors are available in 8 shell sizes with 9 to 100 contacts. Terminations may be straight (BS) or at 90 right angle (BR, CBR) board thickness. Jackpost mounting for use with locking hardware is also available.
