This Electrical Jack set (1 Black, 1 Red) is ideal for building your own charging station or as a 12-24volt power access point for DC power supply applications.
They are designed to pass through wooden or metal facias up to 5mm thick (they are insulated and required a 6mm mounting hole).
These have 4mm holes to suit 4mm male banana plugs.
Rated to around 30amps.
Total length: 15mm
Mounting hole: 6mm
They look a bit cheap but do the basic job I have asked them to do. A bit pricey, you could have expected HK to sell those for much less. I mounted them on a PC power supply (12V 30A) that I use to power my 3 chargers through the power strip that HK sells here.
By the way mounting hole is not 6 mm but 8 mm...Great quality. Used mine (Read: "when I get around to it, I will use") to add external banana connections to a PSUAunque la calidad de las arandelas de plastico no es muy buena, yo la he utilizado para sustituir las que tenia el Control Panel de la caja de vuelo que se habian desecho.Again, I added these to my order to top-off some extra grams. I figured they should come in handy in the future like for perhaps a power supply project - you never know. Also they are at a very reasonable price since I checked around at local retailers and they were double or triple the price Hobby King sells them for.Cheap, ok, what else to say? Works fine, quality ok for the price.well done - price much to high - get some single ones for 0,32 here in germanyVery simple and easy to install. Looks great on my homemade power supply compared to the binding posts I used to have on there.great addition, great for converting computer power system to power battry charger.Nice for power supply conversions running battery chargers.Good quality and reasonable price. Thanks HK!
