Overview
The document describes the Eagle Eye AA, an advanced inductive sensor developed by Roland Electronic for detecting layers, butt joints, and edges in metallic semi-finished products. It operates contact-free and is independent of optical properties, making it suitable for all metals. The sensor is designed for start and stop operations and provides an analog output for connection to a PLC.

Specifications
- Universal inductive sensor principle
- Analog output: 4…20 mA or 2...10 V
- Available in various sizes for different applications
- Supply voltage: 20 ... 28 VDC
- Temperature range: +15°C to +45°C (operation), -20°C to +70°C (storage)
- Conformity: CE

Functionality
The sensor uses an eddy current principle with several coupled bobbins, allowing it to detect structural material boundaries in metals, such as air gaps between butt joints or stacked sheets. It provides significant signals for ferromagnetic materials, which can be processed rapidly with a PLC. The sensor must be adjusted perpendicular to the material transition for accurate measurement.

Applications
The Eagle Eye AA is particularly effective in detecting metallic transitions and is suitable for applications involving ferromagnetic materials. It can be integrated into existing systems using the XA100-S control unit, which provides switching signals for size limits.

Measurement Types
- Static Measurement: The sheet is moved to a constant position in front of the sensor for analysis.
- Dynamic Measurement: The sheet passes the sensor at a constant distance, with analysis occurring during movement.

Technical Data
- Ferrous material detection: Single sheet thickness varies by sensor model
- Distance X: Varies by sensor model
- Time period for analog signal: < 20 ms
- Output voltage load: 100 KΩ (min. 10 KΩ)
- Output current load: 50 Ω (min. 0 Ω / max. 300 Ω)

Order Information
Various sensor models and accessories are available, including sensor cables and connectors. The document provides part numbers and descriptions for ordering.

Conclusion
The Eagle Eye AA sensor offers a reliable solution for detecting material boundaries in metallic products, with versatile applications and easy integration into existing systems.
