The INGUN KS-100 30 (INGUN item KS-10030) is a press-in receptacle for the 100 mil (2.54 mm) grid. It is pressed once into the fixture's probe plate and the spring probe then plugs into it, so a worn or damaged probe can be pulled and replaced by hand without unsoldering or rewiring the fixture.
This is the plain solder-cup variant of the KS-100 press-in range, with a 5.5 mm collar and no press ring. Reach for it where the probe plate sets the installation height and you do not need a press ring to regulate depth; the deeper-collar G and G12 versions exist for exactly that case, and the 05/25/40 versions trade collar height for a shorter overall build.
Total length 32 mm (1.25 in), outer diameter 1.67 mm (.065 in)
Collar diameter 1.8 mm, collar height 5.5 mm; no press ring
Mounting hole 1.69 – 1.70 mm in FR4, 1.68 – 1.69 mm in CEM1
