Inductive proximity sensor NMB series

Some applications place particularly high demands on the robustness of sensors. These rugged and durable "Metal Face“ sensors are enclosed in stainless steel making them the best selection for these tough applications. Applications such as machine tools or metal processing will often expose the sensor to target impact, abrasion and the affects of aggressive solvents and fluid. In these applications, sensors with a stainless steel sensing face may reduce down time and extend service-life making your overall production more profitable. Our "Metal Face“ product series (NMB…) is available in 2 versions, (FE) for detection of ferrous metals and (NFE) for detection of non-ferrous metals. Please note: All product-related documents, such as certificates, declarations of conformity, etc., which were issued prior to the conversion under the name Pepperl+Fuchs GmbH or Pepperl+Fuchs AG, also apply to Pepperl+Fuchs SE.
