{"product_id":"qa-tech-156-prn2541s","title":"QA Tech 156-PRN2541S, Needle Tip, 156mil","description":"\u003cp\u003eThe QA Technology 156-PRN2541S is a conventional spring probe from the 156-25 series: 156 mil (3.96 mm) centres with 0.250 in (6.35 mm) full stroke and a 0.167 in (4.24 mm) working stroke. This is the coarsest of QA Technology's conventional pitches — the series to reach for when test points are widely spaced and the priority is current-carrying capacity and mechanical robustness rather than density.\u003c\/p\u003e\n\u003cp\u003eThe ordering code resolves as follows. N is the tube material: nickel silver, no finish, with under 15 mΩ average resistance and a 16 A rating at 120 °C (22 A at 204 °C) — the economy option of the three tube materials, where an H or S tube would buy lower resistance and a higher current rating. 41 is the 30° spear tip at ø0.068 in (1.72 mm), a concentrated point for small, positively located targets. S is the standard spring at 6.0 oz (170 g \/ 1.67 N) at working stroke, rated for a million cycles. Probes press into a 156-SD 250S socket.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e41 spear tip, 30°, ø0.068 in (1.72 mm); heat-treated BeCu, gold over nickel\u003c\/li\u003e\n\u003cli\u003e156 mil (3.96 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: 6.0 oz (170 g \/ 1.67 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\u003eN tube: nickel silver, no finish; average resistance \u0026lt; 15 mΩ\u003c\/li\u003e\n\u003cli\u003e16 A at 120 °C (22 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 156-SD 250S socket\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FixturFab","offers":[{"title":"Default Title","offer_id":47144973434982,"sku":"201-000035","price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0653\/5387\/5558\/files\/4a43e1f8440d37920d47dbc69ab3ac13.png?v=1788927379","url":"https:\/\/shop.fixturfab.com\/products\/qa-tech-156-prn2541s","provider":"FixturFab Shop","version":"1.0","type":"link"}
