FEATURES
DESCRIPTION
The KMI18/4 sensor detects rotational speed of passive
targets wheels with ferrous reference marks.
It consists of a magnetoresistive sensor element, an
integrated circuit for signal conditioning and a ferrite
magnet.
The frequency of the digital voltage output signal is
proportional to the rotational speed of the target wheel
(see Fig.3).
An open collector output gives high flexibility in the design
of the subsequent signal conditioning.
