RoHS Compliant Brass Terminal Connectors with Insulation and Rectangular Shape for OEM Orders

You're looking at a solid brass terminal connector with insulation built right in, and we've been supplying these to OEM buyers for years — mostly in the industiral electrical and electronic sectors. The rectangular shape is pretty much standard for tight panel layouts, and the silver finish isn't just for looks, it helps with corrosion resistance over time. We turn, mill, and punch these form brass stock, so you get good conductivity without the price tag of copper alternatives.

Basically, if you need a reliable connection point that won't short out against nearby components, the insulation layer is what does the job. Most buyers go with these for control cabinets or junction boxes where vibration is a factor, since the brass holds up better than some plated alloys. One thing that catches people off guard is they're not CNC machined, so if you need ultra-tight tolerances for a micro application, you might want to look elsewhere.

Anyway, our standard MOQ for these is about 500 pieces per spec, and we usually have stock on common sizes in about 20 days or so — confirm lead time for non-standard dimensions. The packaging is straightforward: plastic bags inside cartons, then a wooden case for larger orders to prevent damage during freight. We can provide COAs with each batch, typically from SGS or our own in-house testing, and the ISO9001 certification backs up the process.

(You'll want to check if your application needs RoHS compliance, because these definately meet that, and we can supply SDS and TDS on request for your regulatory filings.) For OEM orders, we can adjust the color or surface finish slightly, but the standard silver is what you get unless you specify otherwise — nickel or tin plating adds about 3-5 business days to the cycle. One concrete detail from handling these: the insulation thickness is consistent within 0.1mm or so across the run, which matters for high-density boards.

They're better than generic terminal blocks for environments where moisture is occasional, but I wouldn't recommend them for submersion application. The brass formulation gives a tensile strength roughly around 350 MPa, which is solid for most push-in connectors, and the rectangular profile reduces rotational slip during tightening.
