Pepperl+Fuchs NJ3CE021025V1 Inductive Proximity Switch

The Pepperl+Fuchs NJ3CE021025V1 Inductive Proximity Switch delivers reliable non-contact metal detection in industrial automation, using inductive sensing designed for hazardous-area and intrinsically safe applications. It features a 3 mm nominal sensing distance, a flush-mount (shielded) cylindrical threaded barrel housing made of nickel-plated brass, and a NAMUR output that interfaces via a M12 V1 connector. With IP67 protection (typical) and operation from 5 to 25 VDC through a NAMUR amplifier, it withstands from -25°C to +70°C (typical) for continuous-duty service in demanding environments. The device is used for metal object detection and machine positioning in conveyors, packaging machinery, assembly equipment, and material handling systems, including chemical plants and oil/gas facilities where hazardous locations require reliable sensing. It offers reverse polarity and short-circuit protection, and certifications noted as ATEX and hazardous location approvals depending on revision. Common replacements include Pepperl+Fuchs NJ2-12GM-N and NJ4-12GM-N for upgrade paths, with the product typically originating from Germany.
