Review on DIYhz GX16 5-Pin Aviation Connector Set: Male And Female Panel-Mounted Metal Plugs And Sockets - Pack Of 5 by Maurice Morris

These plugs look sharp and are sturdy. When the male/female connectors are locked in, there is no play or slop and it's a solid connection. The terminals are easy to solder to (and take/wick the solder well), so it's pretty simple to attach your wiring. I used this to tie another stepper motor into my engraving system and it's basically the perfect connector for that-- 5 terminals for ground, A+, A-, B+, B-.For installing these, pre-solder the ends of your wires, pre solder a bit onto the connector terminal, then touch the two, heat them up, and when the solder melts, the wire and terminal will fit together nicely.
