It seats in a matching KS-series receptacle in the fixture's probe plate, so a worn or bent probe can be pulled and replaced from the top without disturbing the wiring underneath.\u003c\/p\u003e\n\u003cp\u003eFine-pitch probes of this class are what make a dense test grid possible: a slim 0.78 mm barrel lets probes sit at half the centre spacing of a 100 mil (2.54 mm) part, while a full 4.3 mm of working stroke still absorbs board warp and fixture stack-up tolerance. The 0.9 mm tip is the mid-size face for this class — broad enough to spread contact load across a test pad without demanding the open keep-out a larger cone or crown would need — and the 1 N spring is the lighter of the two common forces, chosen to keep total board loading manageable when several hundred probes land at once.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTip diameter 0.9 mm (0.035 in); barrel diameter 0.78 mm (0.03 in)\u003c\/li\u003e\n\u003cli\u003eGrid pitch 1.27 mm (50 mil)\u003c\/li\u003e\n\u003cli\u003eSpring force 1 N at working stroke\u003c\/li\u003e\n\u003cli\u003eWorking stroke 4.3 mm, maximum stroke 6.35 mm\u003c\/li\u003e\n\u003cli\u003eContact resistance 20 mΩ typical\u003c\/li\u003e\n\u003cli\u003eGold-plated plunger; replaceable from the top of the fixture\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FixturFab","offers":[{"title":"Default Title","offer_id":47144979497062,"sku":"201-0023-00","price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0653\/5387\/5558\/files\/bd534ce817925666ac620b556e20c20b.png?v=1788927473","url":"https:\/\/shop.fixturfab.com\/products\/ingun-gks-550-319-090-a-1000-test-probe","provider":"FixturFab Shop","version":"1.0","type":"link"}
