Some terminal blocks have such narrow pitch that an insulated ferrule will not fit. Others provide their own insulation between adjacent terminals. For these situations, uninsulated ferrules are the answer. The QUADRIOS 22C485 gives you 1000 bare copper ferrules in five common sizes: 0.5, 0.75, 1.0, 1.5, and 2.5 mm².

Without the polyamide collar, the ferrule occupies less space and can be inserted deeper into the terminal. Use these when you need to crimp multiple wires into a single block, or when the terminal itself has finger-safe barriers. The 8mm pin length is standard across all sizes. The assortment includes 250 of 0.5, 0.75, and 1.0 mm² each, plus 125 of 1.5 and 2.5 mm². This covers the majority of signal and power wiring needs in industrial control panels.
