Speed sensors type series FAM use the magnetoresistive measurement principle. With this measurement principle, a higher signal resolution can be achieved. It is therefore suitable for applications in which very precise measurement results are required. The input range is designed for frequencies from 0 to 30 kHz. The output frequency can be multiplied if necessary to increase the resolution. In particular, the adjustability with quotients results in new control options for refit projects. The type 52 flange housing is particularly suitable for applications in transport technology. With the type test according to DIN EN 50155, applications in rail vehicles can be implemented.
Due to the measuring principle, high-precise measurement results can be achieved. The sensor can detect any number of threshold points. In use with a toothed wheel, the output frequency can be multiplied by factor 2 or 4. If required, even rations are possible. In use with a magnetic pole wheel, higher multipliers are possible (factors 6 or 8).
Magnetic pole wheel (option)
The magnetic pole wheel enables customer-specific resolution with excellent signal accuracy, even at high speeds. We offer you the right magnetic pole wheels for our sensors or for your application. Talk to our sales staff and let us advise you.
