Most ferrule kits start at 0.5 mm². But what about the thinner wires – the 0.14 mm² thermocouple leads, the 0.25 mm² sensor cables, the 0.34 mm² twisted pair for RS-485? The QUADRIOS 2010C392 fills that gap. This 200-piece kit covers four small gauges that larger assortments ignore.

Gray ferrules for 0.14 mm². Light blue for 0.25 mm². Turquoise for 0.34 mm². Orange for 0.5 mm². Each comes with a polyamide collar that follows DIN color coding conventions for these non-standard sizes. The tin-plated copper barrel is sized precisely for each gauge – no loose crimps. Use these when you are wiring a PLC cabinet with 24V sensor inputs, terminating thermocouple extension wire, or building a control panel with fine-stranded signal cables. The small 8mm pin length fits terminal blocks with tight spacing, where standard 10mm ferrules would crowd adjacent terminals.
