Industry 4.0

In most cases, data exchange with the magnetic encoders is limited to the exchange of process data. In addition to the process data, intelligent drives provide additional information that can be evaluated for condition monitoring up to predictive maintenance:

Process Data Smart Value Smart Function
Actual position Temperature Plausibility monitoring

Hint for mounting

When mounting sensor and magnetic tape, please be careful to align both system components correctly. The arrow marks on the tape and sensor must point in the same direction when mounting the components.

A, Sensor/tape reading distance ≤0.3 mm
B, Lateral offset +0.4 mm, -0.2 mm
C, Alignment error <±1°
D, Longitudinal tilt max. sensor/tape A reading distance must never be exceeded.
E, Lateral tilt max. sensor/tape A reading distance must never be exceeded.
