hi
i am new in this fild and i want to get some information about namur sensors.
would you please help me?

thanks in advance.

 

A NAMUR format is used for 2-wire connections to switching devices such as proximity probes. It operates at two different current levels - typically > 2.1 mA if no object is sensed, <1.2 mA if there is something present. See
for instance http://www.am.pepperl-fuchs.com/pdf/documents/sc04-030.pdf
