Ingun GKS-100 303 200 A 1000 Probe, Cupped Tip, 100mil

The INGUN GKS-100 303 200 A 1000 (INGUN item GKS-100-1983) is a standard-stroke spring test probe on the 2.54 mm (100 mil) grid, plugging into a KS-100 receptacle. The GKS-100 is INGUN's workhorse in-circuit family and the default choice when the fixture is laid out on 100 mil (2.54 mm) centres.

The 03 head is an inverse cone 2 mm across: a concave crater that cups a round target and keeps it centred, which makes it the head for contacting posts, pins and header leads rather than flat pads. The light 1 N spring keeps plate load down on dense fields — step up to a 1.5 N variant where you need more force to break through residue.
