The semiconductive reluctance elemental device (single
crystal InSb) of high sensitivity was designed for the non-
contact potentiometers.
Excellent characteristics by matching with the magnetic
circuitry are exhibited.
s Features
1. There is the following advantage because it is the
contact-less structure that a magnet was combined with
the reluctance elemental device unlike slide wire
potentiometer.
Long life time because a resistor isn't worn away.
No sliding noise.
No hysteresis of the output signal.
Low torque because a shaft is held by the ball bearing.
Mechanical response is excellent and electric response
exceeds the mechanical response fully.
2. The angle detection of
50
is possible.
3. LP05M series is suitable for the high reliability use
because a temperature compensation circuit is built in.
s Applications
Paper thickness measurement for ATM and OCR.
String tension or Tape tension controller
Angle measurement of valve
Level detection of fluid
Rotation angle measurement of servomotor

The figure shows the construction of the non-contact
potentiometer. A magnet is mounted on the end of a rotation
shaft. When the shaft rotates, the magnetic field applied to
the magnetoresistive (MR) elements varies and a quasi-sine
wave signal can be obtained.
In the range near the center of the amplitude of the signal,
the output changes linearly. The rotational angle is therefore
converted into the output voltage linearly.
The magnetic yoke is placed opposite to the magnet in
order to generate a parallel magnetic field and the MR
elements are positioned at the center of the magnetic yoke.
Reference Data
s Construction
A change in the resistance of a ferromagnetic or
semiconductive material when it is subjected to magnetic
flux. Used in Murata's non-contact potentiometer is InSb
which exhibits very high magnetoresitive effect.
s Magnetoresistive
A suitable space gap is meintained between the magnet and
the MR elements. The magnet is made of rare earth metals
having high energy product.
The rotation shaft is supported with two miniature bearings
so that it can rotate smoothly. The life of this sensor
depends on these bearings, and long life performance is
guaranteed by a high precision assembly.
The figure shows the relationship between the magnet and
the MR elements positions, the non-contact potentiometer
equivalent circuit, and the relationship between the angle of
rotation and the output voltage.

Caution/Part Numbering
s Notice (Stroge and Operating Condition)
1. Please do not apply mechanical shock or pressure
on the product, especially to the shaft. Because
it leads to change in the output level or
destruction of magnetoresistive element.
2. Please do not use or keep the sensor in the
corrosive gas(Cl
2
,NOx,SO
2
, and so on). Metal case
might be corroded due to it.
3. Keep the product away from water, chemical solvent
and oil.
4. The terminal should be avoided excessive force,
rotation or bent.
5. Avoid storing and using the product in the
locations where the ambient temperature changes
suddenly.
s !Caution (Handling)
1. Because this sensor contains a permanent magnet,
it could damage magnetic signal in the writable
magnetic card such as train ticket and pre-paid
card. Please consult with us before applying it
in such circumstance.
2. Be sure to provide an appropriate fail-safe
function on your product to prevent a second
