Ingun KS-075 WL Wireless Receptacle

The INGUN KS-075 WL (INGUN item KS-075WL) is a wireless receptacle for the 75 mil (1.91 mm) grid. It carries its own sprung contact on the underside, so instead of being soldered or wrapped it bears on a pad of the fixture's interface board — the probe field is built entirely from press-in parts with no harness behind the plate.

It is the 75 mil member of the KS wireless family, sitting between KS-050/KS-550 and KS-100. Pick it when the board's test-point pitch will not allow a 100 mil grid but the build still needs to be wireless. The underside contact is a self-cleaning 90° three-edged chisel in gold-plated CuBe, which keeps contact resistance stable against a plated interface pad over many cycles.

In Studio this receptacle is paired with the INGUN GKS-075 probe family and with Centalic PE75 probes.
