scope:

This guideline describes the requirements on multicontact connector systems and their realization by a six pin plug. They are directed towards process and laboratory applications as well as portable instruments. The guideline applies to in-line analytical measurements in process engineering and considers particularly areas with high demands on operational reliability and corrosion resistance. It specifies the mechanical and electrical requirements to be met by connector systems for electrochemical sensors such as pH and redox electrodes, conductivity probes, potentiometric measurements and combinations thereof.

It is the intention that the system specified in this guideline can be offered by all manufacturers of inline sensors. This guideline is based on the specifications elaborated in cooperation with manufacturers (suppliers) in the working group AK 3.6.4 pH measurement problems at NAMUR.

The connector system presented here is intended to limit the great variety of connector systems available on the market, and to supersede outdated connector systems. It is expected that the implementation of this guideline will reduce the cost of manufacture as well as the cost of use.
