Pepperl+Fuchs NBN4-12GM40-E2-V1 Inductive Sensor 4mm Range PNP NO Output IP67 M12 Connector

1. Sensing Functionality​

The Pepperl + Fuchs NBN4 - 12GM40 - E2 - V1 is an inductive sensor designed for precise object detection. With a rated operating distance of 4 mm, it can accurately sense metallic objects within this range. The assured operating distance, usually from 0 to 3.24 mm, guarantees reliable performance. It has a high switching frequency of up to 2500 Hz, enabling quick responses to the presence or absence of targets. The PNP output in a 3 - wire configuration makes it highly compatible with a wide variety of industrial control systems. A distinct yellow LED switching state indicator provides clear visual feedback on its operation status, facilitating easy monitoring.​

2. Physical Construction​

Physically, this sensor features a durable nickel - plated brass housing with a 12 - mm diameter. The sensing face, made of PBT material, contributes to its reliable detection performance. It has an IP67 protection rating, which means it can resist dust and withstand temporary submersion in water, making it suitable for harsh industrial environments. The non - flush installation design, along with nuts for mounting and a tightening torque of 0 - 30 Nm, offers flexibility in placement. Additionally, it can operate within an ambient temperature range of - 40 °C to +85 °C, ensuring consistent performance across different conditions.​

3. Electrical Specifications​

Operating within a voltage range of 10 - 30 V DC, the NBN4 - 12GM40 - E2 - V1 is well - adapted to standard industrial power supplies. It comes equipped with reverse polarity protection, safeguarding against incorrect voltage connections that could potentially damage the sensor. The short - circuit protection, implemented as pulsing, ensures the sensor's safety during electrical faults. The voltage drop is ≤ 1.5 V, and the operating current ranges from 0 - 200 mA, while the no - load supply current is ≤ 10 mA. This energy - efficient design makes it an ideal choice for long - term continuous operation in industrial automation setups.
