The Pepperl+Fuchs NBB8-18GM30-E3-V1 is a rugged inductive proximity sensor designed for reliable non-contact detection of metallic objects in tight industrial environments. With an M18 threaded barrel and 30 mm length, its compact form factor allows easy integration into confined spaces, while the rotatable sensing head (360° adjustment) enables optimal alignment for challenging mounting angles. The 3-wire DC PNP output (NO/NC complementary) ensures stable signal transmission across a 10–30 V DC voltage range, supported by a 200 mA load current capacity. Two visible LEDs—green for power and yellow for switching status—provide clear operational feedback, enhancing diagnostic efficiency. Weighing just 90 g, this sensor includes a mounting nut and bracket for quick installation, ideal for machinery with limited space.
Engineered for consistent operation, the NBB8-18GM30-E3-V1 offers an 8 mm rated sensing distance (flush mounting) with a 5% hysteresis for stable signal transitions, minimizing false triggers from vibration or material variance. Its IP67 rating protects against dust and water immersion, while the temperature range of -25°C to 70°C ensures reliability in harsh environments. The polyamide (PA) housing resists chemicals and mechanical stress, complemented by reverse polarity and short-circuit protection for enhanced durability. A switching frequency of 400 Hz supports high-speed applications, such as conveyor belt sorting or robotic arm positioning, while the M12 connector ensures secure, standardized wiring.
This sensor meets international standards (EN/IEC 60947-5-2) and carries CE, UL, and CCC certifications, making it suitable for global automation setups. The reduction factors for non-iron metals (e.g., aluminum: 0.3, copper: 0.2) guide proper target material selection, ensuring accurate detection across industrial use cases. Its flush-mount design reduces interference from adjacent metal surfaces, critical for dense machine layouts in manufacturing, logistics, or process control. With a proven MTTFd of 1500+ years and mission time of 20 years, the NBB8-18GM30-E3-V1 balances precision, ruggedness, and ease of integration, embodying Pepperl+Fuchs’ expertise in industrial sensing solutions.
