Pepperl+Fuchs NBN8-18GM60-WS Inductive Proximity Sensor 18mm Range M12 Connector PNP NO IP67 Factory Automation

Design and Sensing Features

The Pepperl + Fuchs NBN8 - 18GM60 - WS is an inductive sensor. It has a non - flush installation design, which means it can be mounted in a way that the sensing face protrudes from the mounting surface. With an 18 - mm diameter cylindrical housing made of nickel - plated brass, it offers durability. The sensing face is crafted from PBT. This sensor has a rated operating distance of 8 mm. It can accurately detect metallic objects within its sensing range. The non - flush design allows for greater flexibility in applications where the sensor needs to be placed in more exposed positions for better detection.

This industrial automation product operates on an AC voltage ranging from 20 to 253 V. It has a two - wire output type with a normally open (NO) switching function. The switching frequency is 0 - 20 Hz. It features reverse polarity tolerance, protecting it from incorrect voltage connections. The voltage drop is less than 5 V when the load current (I_{L}>50) mA and less than 8 V when (I_{L}<50) mA. The operating current ranges from 5 to 200 mA, and the off - state current is typically 0 - 1.7 mA. There is also a momentary current of 0 - 1600 mA (lasting 20 ms at 0.1 Hz), which can handle short - term high - current demands.

The NBN8 - 18GM60 - WS can function in an ambient temperature range from - 25 °C to 70 °C (-13 °F to 158 °F), making it suitable for a wide variety of industrial environments. It has an IP67 degree of protection, ensuring resistance to dust and water immersion. The connection is made through a 2 - m PVC cable with a core cross - section of 0.34 (mm^{2}) and a cable diameter of 4.6 mm ± 0.2 mm. The bending radius should be greater than 10 times the cable diameter. The housing material's nickel - plating not only provides mechanical strength but also some level of corrosion resistance, contributing to the sensor's long - term reliable operation in harsh industrial settings.
