CB12A Connector Board

High-Density IDC Flat Cables
Shown Actual Size NOTE: Expansion Module Required for Connectors Larger than 60 Pins!

Use CB12A to test high-density flat cables with IDC wiremount sockets (0.025” wire centers, 0.050 x 0.050” pin centers). The pads on this board may also accommodate surface-mount connectors with 0.050" pitch (see close-up of pads below main photo). Three 80-pin positions are available on each board. Because of the many varieties of high-density connectors available, the board is shipped without connectors as shown in the photo. We will populate the board with connectors the User provides, or with standard AMP, 3M, or T&B connectors, for a modest configuration charge; contact us for details. Standard header sizes are: 80, 68, 60, 50, 40, 34, 30, 26, and 20 pins. Important: To use this board with connectors of more than 60 pins, an expansion module is required; see Item 823 (M3U) or 813 (M2U). Set of two boards with expander cable.
