Selection note: The catalog headings say GI12C/GI18C/GI30C, while the model rows say GC12/GC18/GC30. Its GC12 non-flush distance is printed 5 mm while model codes use -04. The A1/A2 rows are labeled DC two-wire; do not infer an AC supply from the letter A.
Values are transcribed from the GWIEC sensor catalog, pages 24–25. A dash means no model is listed in that source cell. Nominal distance and an operating/set distance are different quantities. Select the complete model, output, supply, connection and mounting dimensions together.
