pulse stability
7)
Pulse tolerance
Maximum permissible output frequency
Group delay
Radial nominal (rated) distance between
sensor head and magnetic ring (mechanical
distance)

head and magnetic ring
Max. permissible axial displacement of the
8)
rotor to the stator
Hysteresis of reversing the direction
in the case of relative vibrations between the
rotor and the stator
Torsional vibration of the rotor
Horizontal stator vibration displacement
Magnetic load limit
Remanent flux density
Coercive field strength
Permissible magnetic field strength for
signal deviations
9)
Load resistance
7) At nominal (rated) conditions.
8) The data refers only to a central axial alignment. Deviations lead to a change in pulse tolerance.
9) Note the termination resistances required in accordance with RS-422.
