Product Description
The NJ2-11-N-G Inductive Sensor is an NAMUR-type industrial proximity sensor designed by Pepperl+Fuchs for hazardous area applications (Ex zones). It is used for reliable non-contact detection of metal objects in automation, machine safety, and process control systems.
This sensor is widely applied in oil & gas plants, chemical industries, and explosion-risk environments, where intrinsic safety and high reliability are required.
