Comments

The IEC 60947-5-6/1999-12 NAMUR standard does not impose the operating voltage (open circuit voltage) or the load resistance (source resistance of the
control amplifier), but it defines the test conditions for which, using the sensor voltage/current characteristics with high and low impedance, the normal
operating zones are specified. The great majority of NAMUR sensors use a 12 V supply voltage. Matching the load resistance to the operating voltage allows
the nominal switching distance to be maintained.
