Impressive Detection Capabilities
The NBB20-L2-A2-V1-3G-3D by Pepperl + Fuchs is an inductive sensor renowned for its detection prowess. With a rated operating distance of 20 mm, it can accurately sense metal objects. In practical scenarios, it has an assured operating distance of 0 - 16.2 mm and an actual range of 18 - 22 mm. Its complementary switching function and PNP output type make it highly adaptable in industrial setups. The sensor also features reduction factors for different materials like aluminum ((r_{al}=0.33)), copper ((r_{cu}=0.31)), and stainless steel ((r_{304}=0.74)), allowing for precise detection based on the target material.
Robust Electrical Features
Electronically, this sensor is designed for reliability. It operates within a 10 - 30 V DC voltage range, suitable for various industrial power supplies. The switching frequency of 0 - 440 Hz enables it to respond quickly to object detection. With 5% hysteresis typically, it reduces signal fluctuations. It comes with reverse polarity protection, safeguarding against incorrect wiring, and pulsing short - circuit protection. The low voltage drop of ≤ 2 V and an operating current of 0 - 200 mA ensure efficient power usage. The green LED indicates the operating voltage, while the yellow one shows the switching state, providing clear visual feedback.
Durable Build and Safety Approvals
Built to last, the NBB20-L2-A2-V1-3G-3D has a housing made of PA, which is both sturdy and resistant to environmental factors. The sensing face, also in PA, and the IP69K degree of protection make it dust - tight and capable of withstanding high - pressure, high - temperature washdowns. It can function in ambient temperatures from - 25 to 85 °C (-13 to 185 °F) and be stored between - 40 to 85 °C (-40 to 185 °F). Additionally, it has ATEX and IECEx approvals for Zone 2/22, ensuring its safe use in hazardous areas.
