The Centalic RQ50-WW is a press-in receptacle for fine-pitch probe fields, with a wire-wrap termination. It stays in the fixture's probe plate and the spring probe seats in it, so probes can be exchanged during maintenance without touching the harness.
It is the same 1 mm-hole body as the RQ50-SC, finished with a wrap post rather than a solder cup. On a dense fine-pitch plate that difference matters more than usual: wrapping a post is easier to do cleanly at close spacing than soldering into a cup, and a channel can be re-terminated without heat near neighbouring receptacles.
In Studio this receptacle is paired with the Centalic PQ50-A-4GG (cupped tip) and PQ50-B-4GG (needle tip) probes, and with the INGUN GKS-550 307 090 A 1500.
