Banana Plug, 2 pin, BLACK. Used on umbilical. BNP-1

The BNP-1 (black) double banana plugs are most commonly used on umbilicals for either 2- or 4-wire hard wire communications. However, we have used them on some headsets with boom or hand microphones. The picture to the left shows how you can stack them. The rollover picture shows them connected to an MK2-DCI Intercom.
