The INGUN KS-100 30 25 (INGUN item KS-1003025) is a press-in receptacle for the 100 mil (2.54 mm) grid. The receptacle stays in the probe plate and the spring probe plugs into it, so a probe change during fixture maintenance needs no unsoldering or rewiring.
It sits in the middle of the KS-100 collar ladder: a 2.5 mm collar, taller than the near-flush 05 version and shorter than the 40 version, on the same 26.9 mm body. The collar bears on the plate surface and sets how far the receptacle stands proud, so the choice between 05, 25 and 40 is driven by the probe-plate thickness and the installation height your probe needs.
Total length 26.9 mm (1.05 in), outer diameter 1.67 mm (.065 in)
Collar diameter 1.8 mm, collar height 2.5 mm; no press ring
Mounting hole 1.69 – 1.70 mm in FR4, 1.68 – 1.69 mm in CEM1
