FAM52–One-/two-channel speed sensor magnetoresistive in 2-hole flange design : NORIS Group GmbH

Typical application: Rail Technology (Light & Heavy Rail)
Output signals with a particularly high resolution:
4x frequency multiplication for gears
>4x frequency multiplication possible with pole wheels
When used with a magnetic pole wheel, very accurate measurement results are achieved; quotients can also be used as multipliers
Two square wave signals, phase-shifted by 90°, optionally with inverted signals
Very high immunity to electromagnetic interference (EMI)
Straight or lateral conductor outlet, available with conductor protection system
Available as variant with four output signals

Application range FAM52

This measuring principle allows for particularly high signal resolution, making it suitable for applications where very precise measurement results are necessary. The input range is designed for frequencies from 0 to 30 kHz. The output frequency can be multiplied to increase the signal resolution. Especially through the adjustability of ratios, new control possibilities arise for retrofit projects. The type approval according to EN 50155 allows for seamless application in rail vehicles.

FAM52 with pole wheel

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.
