5 pin connector recommendations that have both male and female sockets available (programming.dev)

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.

What are your other requirements?

  • Is this for a production or a one of a kind hobby/repair project?
  • How budget aware are you?
  • you mention portability. How often would you need to unplug it? And will it be done by you or someone who requires a bit more user proofing?

Have you considered using more than one pin per pole? Ie if you had a 15pin connector, that can take 3A per pin, then shorting 3pins will give you 5 pins 9A. There will be more considerations to this though. Like how can you make sure that the parallel pins present a similar resistance, so you don't get an unbalanced load.

  • One of a kind hobby project. I want to experiment with time of day controlled LEDs, and see how they work as a light based wake up alarm.

  • I'd rather not break the bank for needlessly overkill connectors, the total for the project so far is only ~220$, and I only sporadically work on it.

  • portability isn't all that important, but the chassis the connectors would connect to should preferably be as small as possible. The PWM circuitry without connectors are ~8cmx3cm.

  • I wouldn't mind using connectors with more pins. The primary challenge is just finding a connector with both male and female socket plugs that seems to easy to plug in and out, within specs.

Thanks for the update. In that case I would be looking at terminal block plugs. They can easily handle the current, they come in a wide variety including panel mount, and they're cheap. What's even better, they don't require crimping and one I saw didn't even use screw terminals https://www.digikey.com/en/products/filter/headers-plugs-and-sockets/370?s=N4IgjCBcpgHAzFUBjKAzAhgGwM4FMAaEAeygG0R5YB2BAFhCKtvgFZHKaBOMABg%2BY8ITbmABMA0QxHUuYhgF0iABwAuUEAGVVAJwCWAOwDmIAL7mgA
