Product specication
Rotational speed sensor
KMI15/4
Mounting conditions
The recommended sensor position in front of a gear wheel
is shown in Fig.15. Distance ‘d’ is measured between the
sensor front and the tip of a gear wheel tooth. The KMI15/4
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 11, 12 and 13.
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.17). The influence of gear
wheel module on the sensing distance is shown in Fig.16.
