Selection note: The catalog uses PR, PRT and PRT12 prefixes in different output rows. Codes are retained as printed; confirm the complete suffix and supply rather than assuming that equal housing sizes are interchangeable.
Values are transcribed from the GWIEC sensor catalog, pages 11–12. 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.
