The Pepperl+Fuchs NBB15-U1-E2 (Order Code: 194767) is a versatile inductive proximity sensor from the renowned VariKont® series. Designed for flexibility, this sensor features a rotatable sensing head that can be adjusted in 5 directions, making it ideal for applications with complex mounting requirements.
This cubic sensor offers a 15 mm flush sensing range and a reliable PNP Normally Open (NO) output. Unlike standard cylindrical sensors, the NBB15-U1-E2 utilizes a terminal compartment with screw terminals, allowing for direct wiring without the need for pre-assembled connectors.
Key Features:
- VariKont Housing: 40 x 40 mm standard industrial design.
- Rotatable Head: Sensing face can be oriented up, down, left, right, or front without moving the base.
- Easy Maintenance: 4 LEDs provide 360° visibility of power and switching status.
- Robust Connection: Dedicated terminal compartment (screw terminals) for secure cable installation.
Replacement & Accessories Info
- Alternative for: Replaces older VariKont models with specific mounting bases.
- Recommended Accessories: Modular mounting bracket MHW 01 (Adjustable holder).
Frequently Asked Questions" (FAQ)
- Q: What is the difference between NBB15-U1-E2 and NBB20-U1-E2?
- A: The NBB15 is a flush mount sensor with a 15mm range, while the NBB20 is non-flush with a longer 20mm range.
- Q: How do I wire the NBB15-U1-E2?
- A: This sensor uses a screw terminal chamber. Pin 1 is typically V+ (10-30V), Pin 3 is 0V (GND), and Pin 4 is the PNP Output. Always refer to the wiring diagram on the housing.
