 Explanation
of operation |
Switches on/off when
the magnetic fields from
the S pole and N pole of
the magnet are applied
alternately.
This is principally
applied in detection of
revolution speed. |
Schematic
operation drawing |
|
|
When the S pole of
the magnet approaches
the marked side of the
Hall effect IC and the
magnetic flux density
exceeds Bop, Vout
changes from H to L.
When the N pole of
the magnet approaches
the marked side of the
Hall effect IC and the
magnetic flux density
exceeds Brp, Vout
changes from L to H.

Semiconductor
magnetoresistive element
(SMRE)
Since a Sn doped
single crystal film
InSb is used as a
material for the
sensing element, the
element has
excellent
magnetoresistive
temperature
characteristics and
very small neutral
voltage temperature
drift. This element
is mainly used for
detection of gear
rotation.

- (*1)The
figure represents
the pitch of the
gear to be detected.
If the gear pitch
(crest-to-crest) is
assumed as p, p (mm)
= mπ is obtained.
(Where, m represents
a gear module, and π
indicates the
circular constant.)
- (*2)This
presents the output
terminal voltage
when 5 V is applied
to both ends of SMRE
in non-magnetic
field.
- (*3)This
represents the
change (rate) of the
resistance value
when a magnetic
field is applied.
R(B) and R(0) are
defined as follows:
R(B): Resistance
value at the
magnetic field B =
0.45(T),
R(0): Resistance
value at the
magnetic field B =
0(T)
ΔRin/Rin = (Rin(B) -
Rin(0))/Rin(0)),
ΔRout/Rout = (Rout(B)
- Rout(0))/Rout(0))
