  • 8 pin male and female plug

    I have a project and need a male and female plug and am having some trouble finding exactly what I need, that's not $100+. I am looking for a circular style plug like the one shown, but with 8 pins instead of 7. This will carry high voltage at 3 phase so the pins need to be at least #12 size. One side I would like to have a box mount, the other a 90 degree fitting(just like pic). I have found some really close on ebay but for example I will only be able to find one side(like a male with no female). Would like it to be a secure screw fitting but that's not a deal breaker. Can be metal or plastic. I could also use one with another pin or 2 and just not use those. Any help would be greatly appreciated. Thanks

    What you need is a circular plastic connector, which are available in many forms:

    Once you find some that meet your specs, you can try any of the major distributors such as Newark, Mouser, and Digi-key for price and availability. What are the actual voltages and currents for each contact?

          I've seen connectors like that in Newark Electronics catalog. I bought a couple 8 pins for a project about 20 years ago. Every bit of that connector had to be ordered in pieces.

            It is called an AMPHENOL plug.

              Paul, that may work. That is the best match I have found so far, the only downside being it's an 8 position plug/receptacle. This isn't for something that will be unplugged very often so I could probably get away with marking each end so it doesn't get plugged in wrong.

              Also just noticed both of those are female

                They have keys in the shells that prevent misconnection. Some even can be ordered with different keys for multiple similar connectors.

                  May be a legality in your neck of the woods, but sensible anyway - female (socket) live/supply, male (pins) equipment. So a cable linking equipment to supply needs free male to plug into a socket on the supply, free female providing power to male panel plug on the equipment.

                          The one shown in the OP is an MS (Military Style) connector, from a couple of manuf, but as commented, are $$$'s!
                          The plastic CPC ref by PStechPaul is one I tend to use as a cheaper alternative.
                          Max.

                            They are nornally polarised to only allow connecting one way round and also to prevent cross coupling when there are several close together. Common on military vehicles and aircraft.
                            If using for three phase, however, as there will be up to 4 pins used for something else, beware of routing VFD power and or control wiring through the same plug for interference may cause problems.

                              There are slam-dunk solutions for that. All you need is to throw money at the problem and you can get mil or aerospace connectors that can deal with that no problem. Won't make economic sense, but, who's worried about that?
