Technical Overview
The Pepperl+Fuchs NJ10-30GM-N is a cylindrical M30 inductive proximity sensor with a 10 mm rated flush operating distance and a NAMUR normally closed output. Its two-wire circuit operates at a nominal 8.2 V and accepts 5–25 V, with switching up to 300 Hz; the sensor uses a preassembled 2 m cable rather than an imaging or network interface. A stainless-steel housing, IP66/IP67 protection, and a -25 to 100 °C ambient range support industrial installation, while the manufacturer lists use up to SIL 2.
M30 flush-mounted NAMUR inductive sensor with 10 mm rated sensing, a 2 m cable, SIL 2 capability, and IP66/IP67 protection.
Key Features
- Inductive sensing element; no imaging silicon or pixel array

Suggested applications
Engineering suggestions require suitability checks for your installation.
1. Flush metal-part position sensing
A machine station may need to confirm a steel fixture or component is seated at a repeatable point without a protruding sensor face.
Potential use
The flush-mounted M30 inductive sensor detects metal targets at a 10 mm rated distance and provides a normally closed NAMUR signal for a compatible switching amplifier or intrinsically safe input. Verify target material, assured range, and interface compatibility in the final design.

2. Hazardous-area machine status input
A process machine may require non-contact position feedback near an installation subject to hazardous-area and functional-safety design constraints.
Potential use
The manufacturer lists SIL 2 use and relevant approvals for the sensor variant; its NAMUR circuit can feed an appropriately selected safety or isolated input. Validate the full certificate conditions, installation, and system-level safety calculation before use.
