Dear friends, take a look at the situations in which P+F proximity switches are suitable

I tried using iron, but it didn’t work; copper worked as well, but still not ideal? Everyone, this issue has been resolved. The copper used originally may not have had sufficient purity; later, copper bars from the busbars in the electrical cabinet were used, and that’s when a signal was generated. Thank you for participating
How do you measure what you mean by ‘not working’? Active/passive? Current/resistance setting? Its documentation states that it is only suitable for non-ferrous metals
By replacing the sensor with a different type and connecting it to the original safety barrier, a reaction occurs as soon as metal is touched, and an input is generated at the DI point
So later I tried using copper, but there was no reaction either
Is the output of this sensor you have now of the same signal type as that of your original sensor?
Make sure that the operating voltage of the proximity switch meets the requirements and that the wiring is correct.
