Selection note: The Ø42 SR column is rated 18 mm but lists SR-3020 and ASR-3020B in its NPN rows. The source prints TC0 with a zero in its codes. Confirm these complete model designations before substitution.
Values are transcribed from the GWIEC sensor catalog, pages 21–22. 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.
