Ingun KS-550 WL Wireless Receptacle

The INGUN KS-550 WL (INGUN item KS-550WL) is a wireless receptacle for fine-pitch probe fields. It carries its own sprung contact on the underside and bears on a pad of the fixture's interface board, so the probe field needs no harness at all — press the receptacles in, drop the probes on top, and the interface PCB does the routing.

This is the smallest body in the KS wireless family at 0.95 mm outer diameter, so it is the wireless option when a board's test points are too close together for the 75 mil KS-075 WL. The underside contact is a self-cleaning 90° three-edged chisel in gold-plated CuBe. Note that, unlike the KS-075 WL and KS-100 WL, this variant is not vacuum-tight.

In Studio this receptacle is paired with the INGUN GKS-550 probe family and with Centalic PQ50 probes.
