Overview
The Pomona 1825-2 banana plug is a solderless, stackable connector that terminates quickly using a flat-blade screwdriver and set screw (8-32 single slot). Designed to fit on the end of any 22 AWG to 18 AWG wire, this red connector offers low-cost, tool-free assembly for temporary and permanent test setups. The 1825-2 features screw termination, brass body with nickel plating, polypropylene insulation, and steel set screw with zinc plating.
