Ingun GKS-100 291 090 A 1500 Probe, Needle Tip, 100mil

The INGUN GKS-100 291 090 A 1500 (INGUN item GKS-100-0100) is a standard-stroke test probe on the 2.54 mm (100 mil) grid, plugging into a KS-100 receptacle with quick exchange.

The 91 tip is a self-cleaning single-point dagger. Because the whole spring force is concentrated on one apex, it produces the highest contact pressure of any tip in the family — the reason to choose it is conformal coating, oxide or stubborn no-clean flux that a crown or chisel skates over. At ø0.9 mm the head is fine enough to land inside a via or on a small pad. This is the 1.5 N version of the same geometry as the 2000-spring GKS-100 291 090 A 2000; pick this one when total probe-field load matters and 1.5 N is still enough to break through. Expect the tip to witness the target.
