Precise angle sensor for larger air gaps

news imagedownload
The new AA746 FreePitch sensor from Sensitec comes into play when the application requires a large air gap between sensor and measuring scales providing at the same time high precision. It functions reliably under harsh environmental conditions and is characterised by a higher sensitivity. The design and layer structure are designed in such a way that effective field strengths of the magnetic scale from about 3 mT are sufficient to bring it into saturation mode, thus achieving optimum performance in terms of resolution and measuring accuracy. When designing an encoder system, the AA746 can be placed further away from the measuring standard (e.g. a pole ring). The sensor is ideally suited for heavy duty encoders where thicker walls or greater distances between the sensor and the scale are required. Due to the magnetic, contactless measuring principle, the sensor can be completely encapsulated and extremely robust.
