Product Description
Pepperl+Fuchs NJ1.5-8GM-N Inductive Sensor
Flush-mountable inductive proximity sensor with NAMUR NC output, 1.5mm operating distance, and SIL 2 certification for demanding industrial automation and safety applications.
Product Overview
The Pepperl+Fuchs NJ1.5-8GM-N is a high-performance inductive proximity sensor featuring NAMUR output with normally closed switching function and SIL 2 certification according to IEC 61508.
Constructed with a stainless steel (AISI 303) housing and PBT sensing face, this sensor delivers exceptional durability in harsh industrial environments. With IP66/IP67 protection rating and an operating temperature range of -25°C to +100°C, it withstands challenging conditions.
NAMUR sensors must be operated with approved switch amplifiers (e.g., Pepperl+Fuchs K-System isolated barriers).

Material Reduction Factors
| Material | Reduction Factor |
|---|---|
| Aluminum (rAl) | 0.4 |
| Copper (rCu) | 0.3 |
| Stainless steel (r304) | 0.85 |
Output Characteristics
This sensor features NAMUR output with normally closed (NC) switching function:
| Condition | Output Signal |
|---|---|
| Target not detected (no metal) | Current consumption ≥ 3 mA |
| Target detected (metal present) | Current consumption ≤ 1 mA |
This output type must be connected to an approved NAMUR switch amplifier (isolated barrier) for proper operation. The switch amplifier converts the NAMUR signal to a standard industrial output for connection to PLCs and control systems.
Applications
| Industry | Application Examples |
|---|---|
| Oil & Gas | Position monitoring, level detection in hazardous areas |
| Chemical / Pharmaceutical | Valve position feedback, tank level monitoring |
| Process Automation | Equipment position detection, safety interlock systems |
| Marine / Offshore | Corrosion-resistant position sensing in harsh environments |
| Machine Building | End-stop detection, positioning control |
| Safety Instrumented Systems (SIS) | SIL2-rated limit switches for safety functions |
Typical Use Cases
- Position monitoring of valves, gates, and actuators in hazardous areas
- End-stop detection for linear actuators and conveyors
- Speed monitoring of rotating equipment (up to 5000 Hz switching frequency)
- Safety interlock monitoring for machinery access doors
