Abstract
A monitoring system for connector pins exposed to conductive/corrosive fluids and/or corrosive environments includes a first sensing portion having a pin monitoring section configured to measure a pin current flow of at least one conductor pin, and transfer a first signal. A second sensing portion produces a second signal indicating by a contactless determination the presence of a fastener providing physical connection between an interface member and a component. A decision logic device receives the first and second signals, compares the pin current flow to a predetermined range of values, and isolates electrical power to the conductor pin when the first signal indicates the pin current flow is outside the predetermined range of values. A sensor body created of a non-ferrous material and connected to the component includes a first insert member having the conductor pin and a second insert member defining a sensor sensing proximal presence of the fastener.
