QA Technology designed this series for loaded-board and high-current testing, and it is the coarse-pitch, high-current step above the 100 mil (2.54 mm) range. It mounts in a 125-SD series socket (solder-cup or wire-wrap), so probes are replaced from the top of the plate without re-terminating.\u003c\/p\u003e\n\u003cp\u003eReading the ordering code: G is the tube material — nickel silver, OD gold plated, giving under 15 mΩ average resistance and a 16.9 A rating at 120 °C (23.0 A at 204 °C). 09 is the serrated tip at ø0.100 in (2.54 mm): a broad, toothed face whose many small edges bite through flux residue and oxide across the whole contact area, which is what keeps joint resistance low when the probe is also carrying current. S is the standard spring, 2.2 oz (62 g) pre-load rising to 7.0 oz (198 g\/1.95 N) at working stroke, rated for one million cycles. Plungers are heat-treated BeCu, gold plated over nickel.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e09 serrated tip, ø0.100 in (2.54 mm); heat-treated BeCu, gold over nickel\u003c\/li\u003e\n\u003cli\u003e125 mil (3.18 mm) centres\u003c\/li\u003e\n\u003cli\u003eWorking stroke 0.167 in (4.24 mm), full stroke 0.250 in (6.35 mm)\u003c\/li\u003e\n\u003cli\u003eStandard (S) spring: 7.0 oz (198 g \/ 1.95 N) at working stroke, 2.2 oz pre-load\u003c\/li\u003e\n\u003cli\u003eStainless-steel spring, 1,000,000 cycle life at working stroke\u003c\/li\u003e\n\u003cli\u003eG tube: nickel silver, OD gold plated; average resistance \u0026lt; 15 mΩ\u003c\/li\u003e\n\u003cli\u003e16.9 A at 120 °C (23.0 A at 204 °C)\u003c\/li\u003e\n\u003cli\u003eWorking temperature −45 °C to 120 °C lubricated; to 204 °C unlubricated\u003c\/li\u003e\n\u003cli\u003eSold per unit; requires a 125-SD 250 series socket\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FixturFab","offers":[{"title":"Default Title","offer_id":47144972091494,"sku":"201-000027","price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0653\/5387\/5558\/files\/d08187debf84ce849f955b77b70663b2.png?v=1788927363","url":"https:\/\/shop.fixturfab.com\/products\/qa-tech-125-prg2509s","provider":"FixturFab Shop","version":"1.0","type":"link"}
