CI12A / CI18A / CI30A
GWIEC
CI12A, CI18A and CI30A provide continuous distance-related voltage or current signals. Choose the required 0–10 V, 10–0 V, 0–20 mA, 4–20 mA or combined output, then match the mounting and load.

Selection note: The family headings use GI12A/GI18A/GI30A but the model rows use CI. The CI30A non-flush set-distance cell says 0–18 mm against a 15 mm nominal rating. The load row prints ≥470 Ω for current-related columns; confirm the actual receiver load requirement and output circuit before connection.
Values are transcribed from the GWIEC sensor catalog, pages 24, 26. 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.
