APPLICATION INFORMATION
Mounting conditions
The recommended sensor position in front of a gear wheel
is shown in Fig.11. The distance ‘d’ is measured between
the sensor front and the tip of a gear wheel tooth. The
KMI16/1 senses ferrous indicators like gear wheels in the
‘y’ direction only (no rotational symmetry of the sensor);
see Fig.2. The effect of incorrect mounting positions on
sensing distance is shown in Figs 7, 8 and 9. The
symmetrical reference axis of the sensor corresponds to
the axis of the ferrite magnet.
Environmental conditions
Due to eddy current effects the sensing distance depends
on the tooth frequency (see Fig.13). The influence of the
gear wheel module on the sensing distance is shown in
Fig.12.
