1. Product Overview: PEPPERL+FUCHS NBN4-12GM50-E2-V1 Inductive Proximity Sensor
The PEPPERL+FUCHS NBN4-12GM50-E2-V1 is a rugged inductive proximity sensor designed for reliable object detection in industrial automation environments. Featuring a cylindrical stainless steel housing (M12x1 thread), this sensor detects metallic targets (ferrous and non-ferrous) without physical contact, ensuring wear-free operation. With an IP67 protection rating, it withstands harsh conditions such as dust, moisture, and temperature fluctuations (-25°C to +70°C). The sensor operates on a 10–30V DC supply and provides a PNP normally open (NO) output, making it compatible with PLCs and control systems. Its compact design and high switching frequency (1 kHz) enable precise detection in high-speed automation processes.
2. Key Technical Specifications
- Detection Range: 4 mm (for mild steel).
- Output Type: PNP, NO (3-wire, 2 m PVC cable).
- Supply Voltage: 10–30V DC (±10%).
- Current Consumption: ≤15 mA.
- Switching Frequency: 1 kHz.
- Housing Material: Stainless steel (1.4404/316L).
- Protection Class: IP67 (dust/water resistance).
- Operating Temperature: -25°C to +70°C.
- Certifications: CE, cULus, IECEx, ATEX (Ex II 3G Ex nA IIC T6 Gc).
3. Industrial Applications and Use Cases
The NBN4-12GM50-E2-V1 is widely used in automotive manufacturing for detecting piston positions, robotic arm tooling, and conveyor belt part presence. In food processing, it monitors stainless steel equipment components, while in packaging lines, it ensures precise bottle cap alignment. The sensor’s explosion-proof certification (ATEX/IECEx) makes it suitable for hazardous areas like chemical plants and oil refineries. It also supports position verification in CNC machines and material handling systems, enhancing safety and operational efficiency.
4. Competitive Advantages and Unique Features

- High Precision: Stable detection even in electromagnetic interference (EMI)-rich environments.
- Versatility: Compatible with diverse metallic targets and harsh industrial settings.
- Easy Installation: M12x1 threading simplifies mounting in tight spaces.
- Safety Compliance: ATEX/IECEx certification for explosive atmospheres.
5. Functional Capabilities and Operational Benefits
The sensor delivers contactless detection, reducing maintenance costs and downtime. Its short-circuit and reverse polarity protection ensures system reliability. The PNP output integrates seamlessly with PLCs, enabling real-time feedback for automated workflows. By minimizing false triggers and optimizing cycle times, it enhances production line efficiency. The extended temperature range and IP67 rating ensure uninterrupted performance in challenging environments, making it a cost-effective solution for Industry 4.0 applications.
Core Functionalities
The sensor’s primary function is to detect metallic objects within its range via electromagnetic fields, generating a digital output signal upon target proximity. It includes built-in diagnostics via an LED indicator, providing real-time status updates for operational transparency. The teach-in capability allows users to adjust sensitivity for specific applications, while the robust housing ensures resistance to vibration and shock. With a service life exceeding 10 million cycles, the NBN4-12GM50-E2-V1 is engineered for long-term reliability, making it a cost-effective solution for high-cycle automation systems. Its plug-and-play design further streamlines integration into PLCs or control panels.
