Q10096 3-pin header for analog inputs

Tags: Help, MSXB080

Applies to: SI modules that include analog inputs on 3-pin keyed connectors

I have a board with a 3-pin keyed Molex header for analog inputs. How should I connect to it?

A 3-pin SIP (Molex) header is used primarily for analog inputs on some signal interface (SI) modules. The header is keyed with a 0.10" (2.54mm) spacing. It mates with female (receptable, socket) 3-pin connector on a connecting cable.

    Figures 1a and 1b show the pinout of the 3-pin connector on the input module and the mating connector on the cable.

Mating Hardware

The 3-pin SIP connectors on the expansion boards are Molex part 22-23-2031, or equivalent. They mate with the following parts from Molex for a discrete wire cable:

  • 3-pin connector shell - 22-01-3037
  • Crimp pins - 08-50-0114, 22-30 AWG

Many other connector manufacturers make compatible mating connectors. Manufacturer representatives can generally find mating parts based on the Molex part numbers.
