Due to oxidation and galvanic currents, female and male connections with the same surface treatment should be used.

Example of different surface treatments: Gold (Au), Silver (Ag), Tin (Sn)

- Silver + Tin = Permitted
- Tin + Gold = Not permitted
- Silver + Gold = Permitted




The type of surface treatment on the connector can only be determined by inspection the male connector's pins with a magnifying glass.
