1. General Function and Design
The NBB8 - 18GM50 - E2 - 10M is an inductive sensor by Pepperl + Fuchs. It has a cylindrical design with a diameter of 18mm and a length of 55mm. The sensor has a rated operating distance of 8mm and is designed for flush installation. It uses a PNP output type and operates on a DC voltage. With a cable length of 10m, it provides flexibility in installation and connection within industrial settings. It has a normally open (NO) switching function, which means the output is off until an appropriate metal object enters its sensing range.
2. Electrical Characteristics
This sensor can work within a wide operating voltage range of 5 to 60V. It has a switching frequency of 0 to 1500Hz, which enables it to respond quickly to changes in the presence of metal objects. The hysteresis is typically 5%, ensuring stable switching performance. It offers excellent protection features such as reverse polarity protection, short - circuit protection (pulsing), and inductive overvoltage protection. The voltage drop is ≤ 2V, and the operating current ranges from 0 to 200mA. The off - state current is 0 to 0.5mA typically 0.1µA at 25 °C, and the no - load supply current is ≤ 7mA.
3. Environmental and Mechanical Attributes
The NBB8 - 18GM50 - E2 - 10M is highly resistant to harsh environments. It can operate in an ambient temperature range from - 40 to 85 °C, and the storage temperature range is the same. The degree of protection is IP68 / IP69K, which means it is dust - tight and can be submerged in water and withstand high - pressure water jets. The housing material is brass, nickel - plated, and the sensing face is made of PBT. The cable has a diameter of 6mm ± 0.2mm, and the bending radius should be greater than 6 times the cable diameter. The sensor also has a switching state indicator (LED, yellow) for easy visual inspection of its operation status
