The purpose of this document is to specify the functional requirements for a miniature connector to be used for health monitoring purposes on aircraft (including harsh environments such as found in propulsion systems). It is actually a family of miniature connectors that is specified in this document for various uses (e.g., pin counts) and environments. This specification will be used by the SAE committee for connectors (AE-8C1) to study the feasibility of developing a dedicated connector standard.
