The shaft turns three full turns from end to end, so each turn covers about a third of the range and you can set a voltage, a power supply output or a position reference much more finely. The 10k track is wound from resistance wire, which keeps it stable with temperature and gives a linearity of 0.25%.\u003c\/p\u003e\n\u003cp class=\"nznpd__intro\"\u003eTwo things to check before you buy. The bushing is imperial 3\/8-32, so it needs a 10.5mm panel hole, not the 7mm hole most small pots use. And it takes a 6.35mm (1\/4 inch) knob, or a three-turn counting dial if you want to read the setting.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003csection class=\"nznpd__block\"\u003e\n\u003ch3 class=\"nznpd__h\"\u003eSpecifications\u003c\/h3\u003e\n\u003cdiv class=\"nznpd__specs\"\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eModel\u003c\/span\u003e\u003cstrong\u003eBI Technologies 7386R10KL.25\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eResistance\u003c\/span\u003e\u003cstrong\u003e10k ohm, plus or minus 5%\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eTaper and linearity\u003c\/span\u003e\u003cstrong\u003eLinear, 0.25%\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eTurns\u003c\/span\u003e\u003cstrong\u003e3 turns (1080 degrees), end stops both ends\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003ePower\u003c\/span\u003e\u003cstrong\u003e1.5W at 70 C, down to 0W at 125 C\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eElement\u003c\/span\u003e\u003cstrong\u003eWirewound, 20 ppm\/C wire\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eBody\u003c\/span\u003e\u003cstrong\u003e22.2mm diameter, 19.1mm deep\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eShaft\u003c\/span\u003e\u003cstrong\u003e6.35mm (1\/4 inch), slotted end, 20.6mm long\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eMounting\u003c\/span\u003e\u003cstrong\u003e3\/8-32 bushing, 10.5mm panel hole\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eTerminals\u003c\/span\u003e\u003cstrong\u003e3 solder turrets: CCW, wiper, CW\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eLife\u003c\/span\u003e\u003cstrong\u003e300,000 shaft turns\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nznpd__spec\"\u003e\n\u003cspan\u003eIn the box\u003c\/span\u003e\u003cstrong\u003e1 pot with hex nut and star washer\u003c\/strong\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"nznpd__block\"\u003e\n\u003ch3 class=\"nznpd__h\"\u003eDatasheets\u003c\/h3\u003e\n\u003cdiv class=\"nznpd__ds\"\u003e\n\u003ca class=\"nznpd__dsbar\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0664\/6127\/0112\/files\/Potentiometer-3-Turn-Wirewound-10k-Datasheet-v1.pdf?v=1794219749\" target=\"_blank\" rel=\"noopener\" aria-label=\"Download the 3-turn wirewound potentiometer datasheet (PDF)\"\u003e\n\u003csvg width=\"20\" height=\"20\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\u003e\u003cpath d=\"M14 2H6a2 2 0 0 0-2 2v16a2 2 0 0 0 2 2h12a2 2 0 0 0 2-2V8z\"\u003e\u003c\/path\u003e\u003cpolyline points=\"14 2 14 8 20 8\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e\n\u003cspan\u003eFull technical datasheet\u003c\/span\u003e\n\u003cspan class=\"nznpd__dsmeta\"\u003ePDF\u003csvg width=\"17\" height=\"17\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\u003e\u003cpath d=\"M21 15v4a2 2 0 0 1-2 2H5a2 2 0 0 1-2-2v-4\"\u003e\u003c\/path\u003e\u003cpolyline points=\"7 10 12 15 17 10\"\u003e\u003c\/polyline\u003e\u003cline x1=\"12\" y1=\"15\" x2=\"12\" y2=\"3\"\u003e\u003c\/line\u003e\u003c\/svg\u003e\u003c\/span\u003e\n\u003c\/a\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003csection class=\"nznpd__block\"\u003e\n\u003cdiv class=\"nznpd__qs\"\u003e\n\u003ch3\u003eWiring \u0026amp; getting started\u003c\/h3\u003e\n\u003col class=\"nznpd__steps\"\u003e\n\u003cli\u003e\u003cdiv\u003e\n\u003cstrong\u003eDrill the hole\u003c\/strong\u003e\u003cp\u003eDrill a 10.5mm hole in the panel and leave about 25mm of room behind it for the body and the terminals.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cdiv\u003e\n\u003cstrong\u003eMount it\u003c\/strong\u003e\u003cp\u003ePut the star washer on the bushing, push it through from behind and fit the hex nut on the front.
