The sensor utilizes the orientation of a magnetic field for the
determination of the measure-
ent angle. Therefore, a mag-
m
net is attached to the rotating
shaft. The magnetic field
orientation is captured with an
integrated circuit. An analogue
output signal r
epresents the
calculated angle.
The extreme miniaturization of
the sensor enables the application also in very small installation spaces. The housing is
made of high grade temperature-resistant plastic material.
The sensor is totally sealed
and therefore is not sensitive
to dust, dirt or moisture.
The two-part design of the
sensor Series RFA and its
position marker offers the
customer maximal variability
when mounting the sensor
.
The absence of shaft and
bearing makes the assembly
insensitive for customer application tolerances.
Measurements can be made
transmissively through various
(non-magnetic) materials.
Electrical connection is made
via lead wires.
