Q10096 3-pin header for analog inputs
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.

MSXB080 - Isolated Analog Input Modules
3-pin Molex headers are used for analog inputs on the following model of MSXB080. The model has a front panel with BNC connectors connected to the 3-pin headers.
- MSXB080-03-E3E08-B - eight 16-bit isolated analog inputs
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.
