Ingun GKS-100 217 170 A 1000 Probe, Star Tip, 100mil

The INGUN GKS-100 217 170 A 1000 (INGUN item GKS-100-0142) is a spring-loaded test probe for the 2.54 mm (100 mil) grid, seated in a KS-100 receptacle so it can be replaced from the top of the fixture without disturbing the wiring.

Tip style 17 is a hexagonal pyramid with cutting edges, self-cleaning — several edges land at once and cut through oxide and flux residue on flat plated pads, which is what makes it the general-purpose tip for production boards rather than pristine coupons. At 1.7 mm this is the largest 17 face in the 100 mil (2.54 mm) range: use it on generous test pads where the extra footprint buys tolerance to positional error, and step down to the GKS-075 version where the pad grid will not allow it. The 1 N spring is the lightest of the three stocked forces for this geometry, which matters when a few hundred of these land on the board at once.
