NBB1.5-8GM40-E2-V1 Inductive Sensor | Pepperl+Fuchs | M40, 24V DC, IP69K, 1.5-8mm Adjustable | Pharmaceutical Packaging

1. Sensing Precision and Functional Design

The Pepperl + Fuchs NBB1.5-8GM40-E2-V1 is an inductive proximity sensor engineered for precise non-contact detection of metallic objects in industrial automation. With a rated sensing distance of 1.5 mm (flush mounting), it ensures reliable object detection within an assured operating range of 0 to 1.215 mm, making it ideal for applications requiring high accuracy, such as assembly lines, robotic systems, or material handling equipment. The sensor features a PNP output in a 3-wire configuration, enabling seamless integration with standard control systems. A yellow LED indicator provides clear visual feedback on the switching state, facilitating quick diagnostics and operational monitoring. Its robust design supports a switching frequency of up to 1,500 Hz, ensuring rapid response to dynamic industrial environments.

2. Robust Physical Construction

Built with a durable nickel-plated brass housing and an 8 mm diameter, this sensor balances compactness with mechanical resilience. The sensing face, made of high-quality PPS material, resists wear and chemical exposure, enhancing longevity in harsh conditions. It boasts an IP67 protection rating, offering full dust tightness and resistance to temporary water immersion, suitable for use in wet, dusty, or high-vibration settings. The flush-mount design, compatible with M8 threaded mounting nuts (tightening torque 0–30 Nm), allows flexible installation in confined spaces. Operating across a wide ambient temperature range of -25 °C to +70 °C, it maintains consistent performance in diverse industrial environments.

3. Electrical Specifications and Safety Features

Operating on a stable 10–30 V DC supply, the NBB1.5-8GM40-E2-V1 incorporates essential electrical protections, including reverse polarity protection to prevent damage from incorrect wiring and pulsing short-circuit protection for overload safety. It features a low voltage drop of ≤ 3 V and a maximum operating current of 100 mA, ensuring energy efficiency and stable signal transmission. The sensor connects via a 4-pin M12 x 1 connector, guaranteeing secure and reliable electrical connections. Compliant with industrial standards like EN IEC 60947-5-2, it offers seamless integration into complex automation systems, making it a trusted choice for critical detection tasks where precision and durability are paramount.
