The INGUN KS-100 30 G12 (INGUN item KS-10030G12) is a press-in receptacle for the 100 mil (2.54 mm) grid, fitted with a press ring. It is pressed into the fixture's probe plate and the spring probe plugs into it, so probes can be exchanged in service without unsoldering or rewiring.
The G12 is the long-collar member of the KS-100 press-in family: a 12 mm collar against 7.6 mm on the standard G. Pick it when the receptacle has to reach through a thick probe plate or a plate-plus-spacer stack and still present the probe at the right height; the press ring keeps that installation depth defined and repeatable across the whole field.
Total length 30 mm (1.18 in), outer diameter 1.67 mm (.065 in)
Collar diameter 1.85 mm, collar height 12 mm; with press ring
Mounting hole 1.69 – 1.70 mm in FR4 (1.72 – 1.74 mm with press ring)
