I am a physics student building a simple circuit to be used in a research lab, and I having trouble deciding what type to connectors to use in my design. My design will call for 2 signal inputs, 1 power input and 1 signal output on the pcb. I was hoping to mount the pcb inside an aluminum enclosure, on the panel of this enclosure there will be 3 bnc connectors for the incoming and outgoing signal lines, and a connector for a wall-plug ac/dc adapter for power. My plan was then to solder, on the inside of the enclosure, two wires to each of these connectors and hopefully have each pair of wires end inside some sort of nylon connector which would attach to a receptacle mounted on the pcb (smd, preferably). The connectors should be rated for up to 5 amps, and preferable would stand less than 0.75 in vertical when plugged into the board, however this height requirement can be ignored if necessary. I was wondering if anybody here could point me in the right direction to find something that would work for the nylon connector/pcb receptacle combo?
