I’m looking for a 5 pin connector type that I can easily find chassis plugs for both male and female.

I’ve looked at DIN and mini xlr connectors, but have unsurprisingly been unable to find male chassis sockets.

The pins needs to support 12V 10A*

*realistically only expects about 6-7A flowing through 1 pin and one fourth of that through the 4 others.

    I don’t know how aging affects the LED power draw, according to the manufacturer I shouldn’t expect more than 7.5A. When measuring peak power output, I get only get ~6A total though.

    4 pins are for earth with each (measured) having ~1.5A going through them at peak brightness. The fifth pin must bear the total load of the four other pins.

    Having 5 pins is of course not a strict requirement, it’s just the LED strip that has 5 connections.

    Edit: I should have clarified that the 4 pins “leading to earth” are connected to mosfets controlled by PWM signals, so they aren’t directly connected to earth. Each of the 4 pins carries a unique amount of current. Their total current is flowing through the fifth pin. Sorry for missing out on that detail in the original statement.

        By soldering the ends of the LED, do you mean the 4 earth connections? I should probably have clarified that the 4 “earth” connections only lead to earth when the mosfets connected to the LED is open. Each connection leading to earth is for either, R, G, B or W so they can’t be soldered together.

        Sorry, my original comment was poorly written. While they do lead to earth, there is a mosfet in between each that receives a unique PWM signal. See the edit for more details.

          You could use something like a dsub connector with larger current carrying pins (more expensive) or a more regular connector (e.g. 15 pin dsub) with multiple pins for supply/high current.

          Regular rectangular headers can handle anywhere from 1-5A per pin depending on the connector so you might be able to get away with a 2x4 rectangular header (maybe a few more pins in parallel for everything just for insurance)
