Ingun GKS-075 319 120 A 1000, Cupped Tip, 75mil

The INGUN GKS-075 319 120 A 1000 (INGUN item GKS-075-0722) is a standard-stroke test probe on the 1.91 mm (75 mil) grid, plugging into a KS-075 receptacle with quick exchange.

The 19 tip is a 90° inverse cone, slotted and self-cleaning. Like the plain 03 inverse cone it is shaped to receive a round lead rather than press on a flat pad — the funnel captures and centres a post or pin — but the slots turn the cone's inner wall into cutting edges, so it also scrapes through oxide and flux as the probe compresses, and gives the displaced debris somewhere to go. That makes it the inverse-cone variant to specify for solder-tinned or oxidised through-hole leads, where the smooth 03 cone would make a high-resistance joint. At ø1.2 mm with a 1.0 N spring it fits common header and through-hole lead sizes.
