SV01 Series Notice
s
Notice (Operating and Storage Conditions)
1. Store in temperatures of -10 to +40deg. C and
relative humidity of 30-85%.
2. Do not store in or near corrosive gases.
3. Use within six months after delivery.
4. Open the package just before using.
5. Do not store under direct sunlight.
6. Do not use the rotary position sensor under the
following environmental conditions. If you use
the rotary position sensor in an environment other
than listed below, please consult a Murata factory
representative prior to using.
(1) Corrosive gasses atmosphere
(Ex. Chlorine gas, Hydrogen sulfide gas, Ammonia
gas, Sulfuric acid gas, Nitric oxide gas, etc.)
(2) In liquid
(Ex. Water, Oil, Medical liquid, Organic
solvent, etc.)
(3) Dusty / dirty atmosphere
(4) Direct sunlight
(5) Static voltage nor electric/magnetic fields
(6) Direct sea breeze
(7) Other variations of the above
s
Notice (Soldering and Mounting)
1. Soldering
(1) SV01 series can be soldered by reflow soldering
method and soldering iron. Do not use flow
soldering method (dipping).
(2) The dimension of land pattern used should be
Murata's standard land pattern at reflow
soldering. Excessive land area may cause
displacement due to the effect of the surface
tension of the solder. Insufficient land area
may cause insufficient soldering strength on PCB
(SMD Type).
(3) Soldering conditions
Refer to the temperature profile.
If the soldering conditions are not suitable,
e.g., excessive time and/or excessive temperature,
the rotary position sensor may deviate from the
specified characteristics.
(4) The amount of solder is critical. Insufficient
amounts of solder can lead to insufficient
soldering strength on PCB. Excessive amounts of
solder may cause bridging between the
terminals.
(5) The soldering iron should not come in contact
with the cover of the rotary position sensor. If
such contact does occur, the rotary position
sensor may be damaged.
2. Mounting
(1) Use PCB hole to meet the pin of the rotary
position sensor. If the rotary position sensor
is inserted into insufficient PCB hole, the
rotary position sensor may be damaged by
mechanical stress. (Lead type)
(2) Do not apply excessive force, preferable 9.8N
max. (Ref. 1kgf) when the rotary position sensor
is mounted to the PCB.
(3) Do not warp and/or bend PCB to prevent the rotary
position sensor from breakage.
3. Cleaning
Cannot be cleaned because of open construction.

Notice (Handling)
Uncontrolled mechanical force (except usual rotation on
the hollow rotor of product) may cause a change of
electrical characteristics, an increase of rotational
torque or mechanical damage of the product.
Therefore, please consider the following points
for your design.
1. The product must be soldered by the terminals.
Do not affix by screw clamping to support board
as this could cause mechanical deformation.
2. The connecting shaft must be sustained by the
bearing. No uncontrolled force should be applied
to the hollow rotor.
s
Notice (Other)
1. Please make sure the connecting impedance is not
less than 10M ohm. The rotary position sensor
is designed to connect the output terminal and A/D
port of the microprocessor directly. Therefore,
connecting impedance presupposes certain M ohm and
the contact resistance is set high.
2. To minimize processing errors and rare cases of
noise influence when data is installed,
please consider the following when programming
your software.
(1) Data install should be done plural times and
applied the mean value.
54
9
(2) Data considered as error should be invalid.
(3) If suspicious data is found, the data should be
re-installed.
3. Before using rotary position sensor, please test
after assembly in your particular mass production
system.
4. MURATA cannot guarantee rotary position sensor
integrity when used under conditions other than
those specified in this document.
