{"product_id":"generic-p50-b1-probe","title":"Generic P50-B1 Probe, Needle Tip, 50mil","description":"\u003cp\u003eThe P50-B1 is a spring-loaded test probe from the generic P50 family, the finest-pitch tier of the generic range, used to contact test points on dense PCBs during in-circuit and functional test. It mounts in a matching receptacle in the fixture's probe plate so probes can be changed from the top as tips wear.\u003c\/p\u003e\n\u003cp\u003eReach for a P50 when the target grid is too tight for a P75 — a 1.22 mm (48 mil) minimum centre distance lets probes sit roughly a third closer together than the P75 family allows. The trade is mechanical: the plunger is slimmer, the 75 g spring is lighter, and the probe is correspondingly less tolerant of side load and mis-registration. The B1 spear tip suits bare vias and tinned pads, where the point cuts through light surface residue and self-centres in a plated hole.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSpear (B1) tip\u003c\/li\u003e\n\u003cli\u003eProbe diameter 0.48 mm, tip diameter 0.5 mm\u003c\/li\u003e\n\u003cli\u003eWorking stroke 2 mm, full stroke 2.65 mm\u003c\/li\u003e\n\u003cli\u003eSpring force 75 g at working stroke\u003c\/li\u003e\n\u003cli\u003eCurrent rating 3 A, contact resistance 50 mΩ\u003c\/li\u003e\n\u003cli\u003eMinimum centre distance 1.22 mm (48 mil)\u003c\/li\u003e\n\u003cli\u003eMoving-plate hole diameter 1 mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FixturFab","offers":[{"title":"Default Title","offer_id":47144977006694,"sku":"201-0006-00","price":0.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0653\/5387\/5558\/files\/7ae0f22d9f22fa4d0bfe5466d9cbc03c.png?v=1788927435","url":"https:\/\/shop.fixturfab.com\/products\/generic-p50-b1-probe","provider":"FixturFab Shop","version":"1.0","type":"link"}
