Selection note: The M8 non-flush header says 2 mm while its model prefix is NI3. The BI M12 NPN rows use Bi4-M12 codes, while the distance header is 2 mm and PNP rows use Bi2-G12. Confirm these exact variants before ordering.
Values are transcribed from the GWIEC sensor catalog, pages 14. 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.
