A generic R75-series receptacle for the 75 mil (1.91 mm) grid with a solder-cup termination. It is pressed into the fixture's probe plate and the spring probe seats in it, so probes can be exchanged during maintenance without any wiring work.
This is the solder-cup counterpart to the R75-2W on the same 1.3 mm mounting hole: pick it when the fixture is hand-soldered rather than wire-wrapped. The R-series pattern is what most generic 75 mil probes are built to, so it suits volume builds where a branded body's plating and tolerance are more than the application requires.
In Studio this receptacle is paired with the generic P75-A2, P75-B1 and P75-LM2 probes.
