Selection note: The SC-3020 set-distance cell reads 0–0.7 mm while the detection-distance cell is printed 2 mm. Confirm this operating-distance value before specification. AC and DC versions use different model codes.
Values are transcribed from the GWIEC sensor catalog, pages 11. 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.
