NJ/NBInductive Proximity Sensors — NBB (flush), NBN (non-flush), NJ (PNP and NAMUR versions)
Inductive Proximity Sensors
Pepperl+Fuchs inductive proximity sensors detect metal objects without contact at distances of up to 100 mm. NBB denotes flush mounting and NBN non-flush mounting; the NJ series includes PNP-output versions and NAMUR sensors for hazardous areas (ATEX, IECEx, up to SIL 2). M8–M30 threaded housings in stainless steel or brass, protection up to IP69, switching frequency up to 3000 Hz.
