It spreads the spring load over a wider footprint than a needle, so it marks the target less while the serrations still break through oxide and flux film. That makes it the choice for flat pads and larger test points; use the B needle version where the target is a small pad or via. The 4 oz (122 gf) spring is the mid force of the PQ50 range.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSerrated tip; plunger diameter 0.50 mm, barrel diameter 0.78 mm\u003c\/li\u003e\n\u003cli\u003eRecommended minimum centre spacing 1.27 mm (50 mil); mounting hole Ø1.0 mm\u003c\/li\u003e\n\u003cli\u003eRated stroke 4.30 mm, full stroke 6.35 mm\u003c\/li\u003e\n\u003cli\u003eSpring force 122 gf (4 oz)\u003c\/li\u003e\n\u003cli\u003eCurrent rating 3 A continuous; contact resistance 60 mΩ\u003c\/li\u003e\n\u003cli\u003eBarrel and receptacle bronze, gold plated; plunger BeCu; spring music wire, gold plated\u003c\/li\u003e\n\u003cli\u003eUsed with RQ50 series receptacles\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FixturFab","offers":[{"title":"Default Title","offer_id":47144991883366,"sku":"201-0089-01","price":1.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0653\/5387\/5558\/files\/04f54e057f2d3b5241b2cbf9da40f030.png?v=1788927633","url":"https:\/\/shop.fixturfab.com\/products\/centalic-pq50-h-4gg-test-probe-serrated-tip","provider":"FixturFab Shop","version":"1.0","type":"link"}
