Mains connectors on a stage get treated worse than any signal connector on the same rig. They get dragged through puddles, they get stood on during load in, and they get unplugged by pulling the cable rather than the body. Signal gear fails gracefully when it is abused. Power gear does not.
We build power and speaker connectors on the same line as the rest of our cable hardware, so we see which corners get cut and which ones hold up. Four numbers predict most of it. The keying, the ingress rating, the current rating, and the range of cable the gland will actually seal on. Our IP65 powercon waterproof connector is the part we point at when somebody asks what good looks like.
In and out are keyed differently, and that is deliberate
Power connectors in this family are keyed so a power inlet cannot be mated to a power outlet. It sounds like a nuisance until you think about what happens on a dark stage when a crew links two fixtures the wrong way round and back feeds a live pin.
That is why the input and output set exists as a pair rather than as two of the same part. One female inlet and one male outlet, with a sealing ring on the female end and brass contacts throughout. If your fixtures use NAC3FCA style sockets, that pair is what links them.
Selling them as a set is also better retail. A customer who buys one half of a keyed system and then cannot mate it is a customer who returns it.
IP65 means nothing if the gland does not fit your cable
An ingress rating is measured on a complete assembly, not on the connector body on its own. A shell rated to IP65 will let water in the moment you fit a cable the gland cannot close around.
Our waterproof shell seals on round cable jackets from 8mm to 12mm outer diameter. That range covers most of the mains cable used on stage, and it is the number to check against what you actually buy, because the cheapest way to miss an IP rating is to fit cable that is half a millimetre too thin.
The waterproof powercon plug uses a rubber O ring at the joint and a screw down clamp behind it. The O ring stops water getting in, and the clamp stops the cable pulling the O ring out of alignment, which is the failure nobody notices until the morning after an outdoor show.
Sixteen amps at 250 volts, and the number that gets faked
Our sealed connector is rated 16A continuous at 250V, which is what you want behind a moving head or a small rig of fixtures. That rating only holds if the contacts can carry it without heating, which comes down to material and contact area.
Brass pins carry current well and they resist oxidation, which matters because a connector that sits outdoors for a season will corrode if the plating is thin. Nickel plated contacts survive that better than bare ones, and bakelite bodies survive being dropped far better than the cheap thermoplastic used in the worst copies.
Ask what the contacts are made of and what the shell is moulded from. Those two answers tell you more about whether the rating is real than the number printed on the barrel does.
Terminals, strip length and the bit nobody checks
Our screw terminal version takes 12 to 16 AWG with an 8mm strip. That is a wide enough window for most mains wiring, and screw terminals matter because they can be re terminated on site without a soldering iron, which is what a crew actually needs at eleven at night.
Strain relief is the part that gets skipped. A screw down clamp behind the terminals takes the pull off the conductors, so a cable yanked across a stage loads the shell rather than the joint. Without it, the first hard tug work hardens the copper at the terminal and the joint fails weeks later.
If you are buying pre wired assemblies, ask how the strain relief is fitted and whether it was pull tested. It is the cheapest test in the world and it catches the failure that causes the most callbacks.
Pre-mated ground, and why contact order matters
On our sealed connector the ground pin makes contact before the line pins do. That ordering is not a detail, it is the difference between a chassis that is earthed before it is energised and one that is live before it is safe.
If you are comparing quotes, ask whether the ground contact is pre-mated. It costs very little to design in and it is the kind of thing that only shows up in a spec sheet when a manufacturer is proud of it.
The same question applies to the quarter turn lock. A twist lock that holds under vibration keeps a connector seated through a whole show, and one that does not will walk loose over an evening of bass.
Keeping power and speaker wiring apart on one panel
Power and signal connectors often end up on the same rack panel or the same cabinet, and mixing them up is a classic wiring fault. Speaker connectors in this class use four pins, with 1+ and 1- for lows and 2+ and 2- for highs when bi-amping.
Our 4 pin speakon connector uses brass pins and mates with NL4FC, NL4FX and NL4MP chassis mounts, so it drops into existing cabinets without an adapter. The 4 pole chassis mount is the panel side, on a standard D series footprint with mounting screws included, and it accepts both two pole and four pole plugs.
If you are specifying a panel, decide the power side and the speaker side before you cut it. Retrofitting a different footprint is the expensive part, not the connectors.
How a connector run gets quoted
Ningbo has hosted our plant since 2009, with ten people on design and tooling, and we ship to more than 60 countries. Connectors sit alongside the cable assemblies, the Yinyu cables and the stands that most of the same buyers already take from us.
OEM covers your logo, your bags and your own part numbers. ODM covers the build, so contact plating, shell material, gland range and the locking geometry, settled and tested before tooling is cut rather than negotiated afterwards.
Connector runs are made against an order, so we give you a production slot that fits your quantity rather than a number read off a shelf. We quote DDP, so what you sign off on is what turns up.
FAQ
Does IP65 let me wash the stage down with the connectors plugged?
Yes, on our sealed connector the rating covers hose spray from any direction. The condition is the cable, so the jacket has to sit inside the 8mm to 12mm gland range or the seal will not close.
What cable gauge do the screw terminals take?
Twelve to sixteen AWG, with 8mm stripped off the end. No special tooling is needed, which is why crews can re terminate one on site instead of binning a lead.
Will this work on 220V as well as 110V?
The connector is rated to 250V maximum, so it covers both European and North American mains. What you need to check separately is the cable and the fixture it feeds, not the connector.
Can a four pole chassis mount take a two pole plug?
Yes. The 4 pole chassis mount accepts both two pole and four pole speakon plugs, and it comes on a standard D series footprint with mounting screws, so it fits most cabinet cut outs without modification.
How do I wire four pins for a bi-amped cabinet?
Pins 1+ and 1- carry the lows and 2+ and 2- carry the highs. Check the amplifier manual before you wire it, because a couple of manufacturers number theirs differently.
Do you hold connectors in stock?
They are produced against an order, so we quote a build slot matched to your quantity. Send the part, the quantity and the destination port and we will come back with a DDP figure.
Tell us what it has to survive
Send over what the connector feeds, whether it lives outdoors, the cable jacket you intend to use and how many you need in the first run. You will get back a gland range that actually seals on your cable, a contact specification that carries the load, and a straight answer if an indoor connector is honestly all the job needs.
