We’ve been shipping these JK2.5B push-in terminal blocks for a while now, and they’re a solid choice for DIN rail setups where you need tool-free wiring with ferrules or solid conductors—the spring mechanism really cuts down insertion force by about half, so it’s faster on repetitive connections. They’re made form flame retardant PA66 nylon with a brass conductor and stainles steel spring, and the high-temp resistance means they hold up better than some generic blocks we’ve tested internally.
Most buyers ask about bulk pricing first, and we typically offer better rates at 500 units or so per order, but MOQ is flexible—just confirm your volume and lead time, as we usually stock but can shift by a couple of weeks. One thing we mention is that these aren’t suited for heavy-duty industrial vibration environments; for that, you’d want screw-type terminals with higher clamping force.
The front connection design is handy for tight panel spaces, and it’s basically a pluggable terminal block with a welding contact termination—so you can pre-wire teh plug and snap it onto the rail later. I’ve seen buyers use these for PCB interfaces in control cabinets, and the compact shape (roughly 2.5mm pitch) works well for that.
Trust comes down to consistency, and our company provide COA and TDS with every shipment—HPLC purity data if needed, though for terminal blocks that’s less common. The manufacturing process here is injection molding, and we’ve had few returns on the JK2.5B model compared to our screw-type line, probably because spring mechanism is simpler to assemble.
The JK2.5B is made from flame-retardant PA66 nylon, which gives it good high-temperature resistance — generally rated up to 105°C continuous, with short spikes up to 120°C depending on the application. It's injection-molded, so the material holds up well under heat.
We can provide material certifications for the PA66, brass conductor, and stainless steel spring, plus a test report for flame retardancy (UL94 V-2 or V-0 depending on batch). Just let your sales contact know what specific docs you need when you place the order.
Our standard MOQ for the JK2.5B is 500 pieces per model, but we can sometimes negotiate lower quantities for first-time orders or samples. Reach out to our team to check current stock and options.
For standard orders of the JK2.5B, lead time is usually 15 to 25 working days, depending on quantity. If you need a rush, we can prioritize production for an additional fee — just ask.
They come in bulk in sealed plastic bags or boxes, depending on the order size, with each batch clearly labeled with model and quantity. For larger orders, we use cartons with inner dividers to prevent damage during transit.
