You choose colour, each “item” you buy is 1 socket, if you want 2 sockets, buy quantity 2.
If you want a red and black pair, see my other listing here for that.
Standard 4mm Banana Socket (Safety Type but will of course also accept standard non-safety banana plugs).
Bezel is 14.5mm diameter, hole required 12mm diameter, about 26mm total length behind the panel plus whatever the length of your spade connector is.
There is a flat-side if you want to key your hole.
Wire connection is a 6mm spade terminal, see my other listings for 6mm blue spade crimping terminals. Of course you could solder to it if you wanted.
These a great for your DIY test equipment, power supplies, dummy loads, resistance boxes and so forth.
I don't have a definitive current rating for these but in theory a well crimped 6mm spade should be good for 15A, but tread carefully if you are drawing more than about half of that rating, you know how optimistic Chinese market sellers are )
See my other listings for good quality Banana plugs which will fit into these sockets.
