Reliably Detect More than One Metal with No Adjustments, No Modifications and No Downtime

Long range inductive proximity sensors with reduction factor 1 detect all metals at the same operating distance

Pepperl+Fuchs introduces NRB/NRN Series inductive proximity sensors with reduction factor 1 .  These sensors are capable of detecting every kind of metal at the same operating distance, and over significantly greater operating distances than is possible with standard inductive sensors.  As a result users benefit from greater flexibility, increased productivity and reduced operating costs to optimize machine designs in virtually any application.

A complete portfolio of flush and non-flush mount sensors with reduction factor 1 is available.  Cylindrical sensors are available in diameters as small as 6.5 mm up to 30 mm with operating distances of 1.5 mm up to 25 mm; including our unique NRB12-18GS40-E2-V1 model, our longest range in an 18mm barrel diameter. Cube-style sensors are available with dimensions of 40 mm x 40 mm or 80 mm x 80 mm with operating distances ranging from 15 mm to 50 mm.

For particularly harsh application environments these sensors are available with a PTFE coated brass shell (cylindrical models) or a coated metal housing, enabling them to withstand the impact of metal shavings and showers of hot weld splashes common to automotive manufacturing environments.

Sensors with reduction factor 1, like the short range NRB2-8GS40-E2-V1, are equipped with a special air-core coil system that is precisely adjusted to ensure that target detection is independent of the metal characteristics and provide the greatest possible operating distances.  The air-coil system makes these sensors insensitive to interference from frequency converters or strong magnetic fields created in welding operations
