Life of connector (general concept of product's life)
Contact failures and breakages are judged as the life of the connector, but regarding such a lifetime, connectors do not have life by operation time.
The connectors' life is judged by mechanical deterioration, environmental deterioration, and electric deterioration, etc. .
However, in either case, the judgment will change depending on which condition is judged as life.
It depends on the environment in which the connector is used, the deteriorated state, the required level for the connector of the application being used, and so on.
Life of the connector itself is judged by contact resistance and the number of insertion and extraction since the connector is a mechanical part (connection part) and is not a part that operates something (an active part) or a part that operates with something (a passive part).
