Eagle Eye AA Eddy Current Sensor

Product catalog summary

Overview
The document describes the Eagle Eye AA, a universal inductive sensor designed for detecting layers, butt joints, and edges in metallic semi-finished products. It operates contact-free and is independent of optical properties, suitable for all metals, and can be used in start and stop operations. The sensor provides an analog output of 4…20 mA or 2...10 V for PLC connection and is available in various sizes for different applications.

Specifications

Detection Principle: Inductive, suitable for metallic materials.
Output: Analog 4…20 mA or 2...10 V.
Supply Voltage: 20 ... 28 VDC.
Temperature Range: +15°C to +45°C (operation), -20°C to +70°C (storage).
Conformity: CE certified.

Functionality
The sensor uses an eddy current principle to detect material boundaries, such as air gaps between stacked sheets or butt joints. It requires perpendicular adjustment to the material transition for accurate measurement. The sensor's signal can be processed by a PLC or the XA100-S control unit, which provides switching signals for size limits.

Applications

Detection of structural material boundaries in metals.
Suitable for ferromagnetic materials with significant signal indication.
Can be used for static and dynamic measurements.

Technical Data

Single Sheet Thickness: 0.2 ... 4 mm for ferrous materials, 0.4 ... 8 mm for others.
Distance X: 0.5 mm to 9 mm depending on the sensor model.
Output Load: Voltage load 100 KΩ (min. 10 KΩ), Current load 50 Ω (min. 0 Ω / max. 300 Ω).

Order Information

Sensors: Various models like AA90x60-453F2S, AA90x60-902F8S.
Cables: Standard length 5 m, other lengths available on request.
Accessories: Harting connector available.

Conclusion
The Eagle Eye AA sensor is a versatile and reliable solution for detecting metallic transitions in industrial applications, offering easy integration with existing systems and robust performance across various conditions.

EAGLE EYE AA With the eddy current sensor AA-type, Roland Electronic has succeeded to develop an amazing sensor. The sensor, consisting of several coupled bobbins, reminds in the figurative sense the vision of the giant Argus (Eagle) in Greek mythology. If something comes into the inductive „field of view“, then it will not loose the sight of it. When processing sheets, strips and other semi-finished metallic products, such as stacked sheets or individual segments of coil packages, a secure and reliable detection of sheets, of coil segments or butt joints becomes necessary.
