The INGUN KS-810 (INGUN item KS-810) is a press-in receptacle for the HFS-810 high-frequency probe series. INGUN describes it as a long receptacle with crimp points: the receptacle stays in the fixture plate and the probe plugs into it, so an HFS-810 contact can be exchanged during maintenance without rebuilding the coaxial connection.
It is a large-bore part — 5 mm outer diameter into a 4.98 – 4.99 mm hole — with a near-flush 0.4 mm collar, so almost the whole 22 mm body sits inside the plate. Specify it when the fixture uses HFS-810 probes and you want them serviceable rather than permanently installed.
Total length 22 mm (.866 in), outer diameter 5 mm (.196 in)
Collar diameter 5.3 mm, collar height 0.4 mm; no press ring
