Ingun GKS-075 204 115 A 1000 Probe, Crown Tip, 75mil

The INGUN GKS-075 204 115 A 1000 (INGUN item GKS-075-0180) is a spring-loaded test probe for the 1.91 mm (75 mil) grid, seated in a KS-075 receptacle so it can be replaced from the top of the fixture without rewiring.

Tip style 04 is a four-point crown — four points that straddle a rounded target and grip it from all sides, so the probe stays put on a pin, a post or a trimmed component lead where a flat or bullet-nosed tip would slip off the shoulder. Splitting the contact force four ways also lets it cut through light oxide without concentrating everything on one point. INGUN list this item for contacting pins, posts and pads, which makes it a useful general-purpose choice on mixed-technology boards. At 1.15 mm the crown is compact for the 75 mil (1.91 mm) range, and the 1 N spring keeps aggregate board load low.
