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.
