Doug- I recall using plastic caps, molded with an electrically conductive filler, at my former employer. Perhaps this is what is needed, though someone else could probably address the minimum required conductivity and dissipative characteristics of such a cap/plug. Don't recall if Caplugs Inc., makes these.

The end of the connector contains several pins that are attached to the circuit board assembly inside. We place a polypropylene "cap" over the end of the connector to protect the threads and the pins within the connector. Our customer is questioning the placement of this cap over the pins due to an ESD concern - static charge??? What could I tell them? Am I wrong for placing this cap, or this type of cap over the pins due to an ESD concern? Douglas A. Hooper, Sr. Luminescent Systems, Inc.
