ddl, Have you checked with an electrical or electronics supply? What you describe sounds like it may be designed for a specific use within a certain industry, whichever that may be. I haven't posted here in a while. Heck, I haven't fished in two years. Valentine's Day 2019 was walking on the side of the road that connects to my street. Long story short, I was hit by a drunk driver in an SUV. He went to prison. I went in the hospital for five months, the first month in a coma due to a skull fracture and multiple other injuries. After that more than a year in physical and cognizance therapy. Anyway~ Putting two metals together, especially in a wet environment can cause bad things to happen.Corrosion. I learned all about that as a helicopter mechanic in the Marine Corps and later aviation maintenance. "Crud control" (corrosion) is a constant battle on aircraft. Google "dissimilar metal corrosion" and read up. Any two metals in contact is problematic, some combinations are worse than others. Keywords are electrolisys, atmospheric, and galvanic corrosion to name a few. If you must go with two different metals in close proximity with each other finding a means to isolate them or insulate them from one another is key. Good luck.
