It's not going to fit every panel-mount IEC inlet you've got—the set screw collar adds about 4mm to the overall length compared to a standard chuck-style connector, so check your chassis depth before ordering.

Most buyers go with the rhodium plating anyway, as it holds up better against oxidation in humid listening rooms than silver, though gold is actually easier to solder if you're terminating your own cables.

non-magnetic matrial composition matters more than most spec sheets suggest, since ferrous components in the signal path introduce measurable inductance artifacts in the 20kHz-50kHz range that pure copper and brass pins eliminate.


our company can do custom plating runs for MOQs of 100 units or so, but the standerd gold/silver/rhodium options ship within roughly 20 days and come with full HPLC-verified COAs on the conductor purity.

Basically, if you're terminating a 12AWG or thicker power cable with a 18mm outer diameter, the set screw mechanism gives you about 4.5Nm of clamping force before teh brass screw starts to deform the wire strands—test that before final assembly.

CE and ROHS certs are on file, but we usually have stock of the gold-plated variant in 200-piece lots—the silver plating takes about 2-3 weeks longer due to the electroplating cycle, so plan accordingly.
Our standard MOQ is 100 pieces, but we can negotiate for sample orders. Yes, we offer customization on plating (gold, silver, or rhodium) and shell finish, including anodized aluminum or brass covers.
Lead time is usually 15-20 working days for standard orders, depending on the quantity and customization level. We can expedite smaller batches if needed.
Yes, we include CE and ROHS certificates with every shipment. We can also share test reports on request.
Yes, the set screws are designed to grip the cable securely without crushing the pure copper pin. The non-magnetic zinc and brass materials ensure reliable contact up to 10A and 250V.
Keep them in a dry, room-temperature environment, ideally in sealed packaging to avoid tarnishing. The carbon fiber and zinc shell is durable, but avoid prolonged exposure to moisture or direct sunlight.
