Functional Specification of Miniature Connectors for Health Monitoring Purposes
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.
Rationale: Data is the raw material to develop health monitoring functions. But due to the data acquisition chain, collecting data can have a negative impact on weight and complexity. One of the significant contributors to the weight of the data acquisition chain is the connectors. Connectors qualified for the severe environments such as for propulsion systems can be bulky and heavy. Some might argue that wireless communication is a solution, but wireless communication is not always preferable. Moreover, even for wireless communications connectors can be necessary. In order to collect more data and develop health monitoring functions with minimum impact on weight, it appears necessary to reduce the size of connectors.
