Most prox sensors don't even work until they have 7V on the supply side. PNP Proxes take the output wire up to the supply voltage, so you will need to be careful. (Which is why NPN can be better, but not with a 7i77 as that has sinking inputs. For a parallel port you can use a 24V NPN prox straight into a parport pin. Though it takes a measure of self-belief...) -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
