Ingun GKS-135 307 150 A 1500, Chisel Tip, 100mil

The INGUN GKS-135 307 150 A 1500 (INGUN item GKS-135-0045) is a long-stroke test probe on the 2.54 mm (100 mil) grid. Its 9.3 mm working stroke is more than double a standard GKS-100's, which is what you need when targets sit at very different heights, when the board bows under load, or when a contact has to reach down into a recess.

The 07 tip is a self-cleaning 90° three-edged chisel at ø1.5 mm — a broad, wiping contact that keeps resistance low on solder without the point loading of a dagger. This is the 1.5 N version of the same geometry as the 2000-spring GKS-135 307 150 A 2000: pick this one when the extra stroke is what you are after and total probe-field load, not contact force, is the limiting factor. Despite the long travel it still uses the standard KS-100 receptacle.
