Micro-D PCB - .050" Contact Spacing
MDM-PCB
How to Order - MDM-PCB Series
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 90û (BR, CBR) board thickness.
Jackpost mounting for use with locking hardware is
also available.
