Ingun GKS-550 201 050 A 1000, Needle Tip, 50mil

The INGUN GKS-550 201 050 A 1000 (INGUN item GKS-550-0027) is a short, robust test probe on the 1.27 mm (50 mil) grid. The GKS-550 is INGUN's compact fine-pitch family: at 34.6 mm overall it is around 8.5 mm shorter than the equivalent GKS-050, which lets the whole probe-plate stack sit lower and leaves less unsupported barrel to bend under side load — a real concern at 50 mil (1.27 mm) pitch. It takes the KS-550 or KS-550 WL receptacle and supports quick exchange.

The 01 tip is a self-cleaning 30° needle at ø0.5 mm: the sharpest and narrowest head, chosen when the target is a small fine-pitch pad or land that a crown would overhang. It is rated for pad contact only and will witness the surface. Fitted with the 1.0 N spring, and rated at 2 A — treat these as signal probes.
