The RFD 4000 utilizes a
separate magnet or magnetic
position marker, attached to
the rotating shaft to be
measured.
The orientation of the magnetic
field is measured and an
analog voltage representing
the angle is the output signal.
The very compact physical
dimentions allows installation
in small spaces. The housing
is made of high grade
temperature-resistant plastic
material. The sensor is sealed
and is not sensitive to dust,
dirt, or moisture.
The two-part design, with the
RFD sensor itself, and its
magnetic position marker,
offers great flexibility when
mounting. The absence of
shaft and bearing makes the
assembly much less sensitive
to axial and radial application
tolerances. Measurements
can be made transmissively
through any nonferromagnetic
material.
Electrical connection is made
via lead wires.
