Q10079 68-line leaf-spring I/O connector

Tags: Help, analog I/O

Applies to: PCI DAP, accessory boards with 68-line leaf-spring connector

I have a board with a 68-line leaf-spring connector for analog I/O. How should I connect to it?

Female (receptable, socket) 68-line leaf-spring type connectors are used primarily for analog I/O PCI DAP boards and some analog expansion boards. They are D-shaped connectors with a double row of pins on 0.050-inch centers. They mate with male (plug) 68-line connectors on connecting cables. A picture of a leaf-spring type connector is shown below:

  1. PCI DAP - PCI Data Acquisition Processor board

    A female 68-line connector is used on the following models of PCI DAP boards for analog I/O:

    • DAP 4000a
    • DAP 4200a
    • DAP 4400a
    • DAP 5000a
    • DAP 5016a
    • DAP 5200a
    • DAP 5216a
    • DAP 5380a
    • DAP 5400a

    The 68-line connector on the PCI DAP is different from that on the xDAP. Figures 2a and 2b show the pinout when connecting to the 68-line connector on a PCI DAP, with the corresponding connections on the male connector on the cable.

  2. MSXB028 - Simultaneous Analog Inputs

    The female 68-line connector used on PCI DAP boards is also used on the following models of the MSXB028 expansion boards, where m and n denote version release and package form, respectively:

    • MSXB028-m-A2Z, MSXB028-01-n2A, and MSXB028-m-n2Y - 16 single-ended simultaneous analog inputs

    The pinout of the connector on the board and the corresponding connections on the male connector on the cable are shown in Figures 2a and 2b above.
