Ingun GKS-100 291 090 A 2000 Probe, Needle Tip, 100mil

The INGUN GKS-100 291 090 A 2000 (INGUN item GKS-100-0003) is a standard-stroke spring-loaded test probe on the 2.54 mm (100 mil) grid, plugging into a KS-100 receptacle with INGUN's quick-exchange system.

The 91 tip is a self-cleaning single-point dagger. All 2 N of spring force lands on one apex, which gives it the highest contact pressure of any tip in the GKS-100 range — the reason to specify it is conformal coating, heavy oxide or a no-clean flux residue that a crown or chisel would skate over. At ø0.9 mm the head is small enough to land inside a via or on a tight pad. Expect it to witness the target; on cosmetically sensitive surfaces use the 14 crown or 05 bullet-nosed tips instead.
