Pepperl+Fuchs NBB5-18GM50-E2 Inductive Proximity Sensor, 5mm Sensing Range, PNP NO, 10-30V DC, M12 Connector

The sensor operates on a wide DC voltage range from 10V to 30V. This flexibility allows it to be powered directly from common industrial 24V DC power supplies or lower voltage PLC output rails, ensuring compatibility with a variety of control systems without requiring additional voltage regulation.

A PNP (sourcing) Normally Open output means the sensor's signal wire is internally disconnected from the positive supply when no target is detected. When a metal target enters the sensing range, the internal switch closes, connecting the signal output to the positive supply voltage (+Vs). This configuration is typically wired to the sinking digital input of a PLC or controller.

Yes, the NBB5-18GM50-E2 is designed for flush mounting. Its sensing face can be installed level with or behind a surrounding metal surface without a reduction in its nominal 5mm sensing distance, making it ideal for space-constrained or protected installations where the sensor needs to be recessed.

This sensor is equipped with a standard industrial 4-pin M12 male connector. This quick-disconnect interface allows for fast installation, easy replacement, and reliable connections in vibration-prone environments, compatible with standard M12 female cable assemblies.

With its IP67 protection rating and nickel-plated brass housing, the sensor is highly resistant to dust ingress and can withstand temporary immersion in water up to 1 meter for 30 minutes. It is suitable for damp industrial environments, washdown areas, and outdoor applications where it is protected from direct, high-pressure water jets.
