Ingun GKS-075 319 120 A 1500 Test Probe, Cupped Tip, 75mil

The INGUN GKS-075 319 120 A 1500 (INGUN item GKS-075-0669) 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 19 is a 90° inverse cone with a slot cut across it, and is self-cleaning. The cone captures a rounded target — a solder bump, a trimmed lead, a wire end — while the slot edge scrapes residue off it as the probe compresses, so it handles the awkward case of a raised target that is not reliably clean: a plain cup would ride on the oxide, and a needle would slide off the dome. At 1.2 mm it is the mid-size cone in the 75 mil (1.91 mm) range. The 1.5 N spring provides enough force for the slot to do its scraping work without the board loading of a 2 N probe.
