Basically it's a pluggable terminal block with a spring-clamp mechanism and a test hole built in — the MK5-9525 handles up to 24 connections (02 to 24 poles depending on how you order), and the insulating material is PA with a V0 flammability rating per UL 94.
Mostly you'll see these on PCBs in industiral control cabinets or automotive application where you don't want to screw around with loose wires. parallel incoming line design plus the test hole means you can check connections without yanking teh whole plug out, but it's not for high-vibration environments — the spring connection can fatigue over time if you're cycling it daily.
Stripping length is 10mm, max flexible conductor it takes is 1.5mm², and the screw-and-spring connection means it's a tight hold rather than a purely spring-loaded one. We've had buyers who prefer the 02-12 pole configurations for smaller builds since they're easier to handle on the bench (the 24-pole version gets a bit unwieldy without a fixture).
Injection molded construction gives decent high-temp resistnce, but don't expect it to survive soldering iron abuse right at the contacts — we usually have stock on most pole counts, but confirm lead time if you need 500+ units or so.
What it does well is prevent misconnection — the plug and socket are keyed so you really have to try to jam it in wrong. Most buyers we deal with just want the COA and reliable batch-to-batch consistency.
You'll get them in standdard anti-static trays if you're ordering under 1000 pieces, bulk bagged above that, and the UL certifcation is active — our company can provide the cert numbers on request but honestly nobody bothers checking for the smaller orders.
Our MOQ for the MK5-9525 is typically 100 pieces, but we can work with smaller quantities for sample orders or first-time buyers. Just let us know your needs.
The MK5-9525 has a flammability rating of V0 per UL 94, and we can provide a material certification for the PA insulating material upon request. We also offer a test report for the high-temperature resistance feature.
Yes, we can customize the number of connections from 02 to 24 poles, so you can get exactly what your PCB layout needs. Just specify the pin count in your order.
Store them in a cool, dry place away from direct sunlight and heat sources, ideally between -40°C and 80°C. This keeps the PA material stable and the spring mechanism working smoothly.
The stripping length is 10 mm, which is designed to ensure a secure screw and spring connection without exposing too much bare wire. Stick to that length for best contact and to avoid short circuits.
