Each specification is defined by testing above items individually.
When shifting the sensor output from H to L, please make sure the magnetic field
applied to the sensor becomes higher than the above operating magnetic field (Hon)
through your designing.
NOTE3) When shifting the sensor output from L to H, please make sure the magnetic field
applied to the sensor becomes lower than the above operating magnetic field (Hoff)
through your designing.
NOTE4) Sensitivity selection of this product is performed at Vcc=1.8V. Operating magnetic field
can possibly change when applying the supply voltage other than 1.8V. Please consult
with us for technical assistance when you consider the supply voltage other than 1.8V, as
a special attention needs to be given in the design.

7. CAUTION FOR USE
7-1 HANDLING
・ This product may be degraded by electrostatic discharge. It is necessary to take anti-s
tatic precautions when handling.
7-2 DESIGN
・ Please thoughoutly evaluate this product for the magneto-variation of the magnet used along
with this product, otherwise this product may result in the miss-operation or the
non-operation.
・ Sensor miss-operation or non-operation may occur due to the influence of the magnetic
noise from surrounding devices such as motor.Please make sure there is no influence of the
magneti noise in designing process.
・ Please be careful about a magnetic body (Iron, Nickel, etc.) and a magnetic noise immunity
that may affect the magnetism of a magnet.
Please do not supply inverse voltage or excess voltage to this product. If applied, this p
roduct may be damaged and electrically destroyed.
・ Please design your product not to be affected by stress of the resin due to heat shri
nk.
・ It is effective to make the Vcc and GND line wide and short or to adopt multi-layer PCB for
switching noise protection. In addition, please place a bypass capacitor near the sensor.
7-3
Storage condition
・ Recommended storage conditions are listed below.
Temperature : +5 to +30oC
Humidity
: 70%(RH)% and lower
*Desiccator storage or storage in N2 atmosphere is recommended.
・ Allowable storage time of the product is one year from the date of delivery. Please take
account of the storage conditions listed above. Please also use the product as soon as
possible after opening the product packing to avoid the deterioration of solderability.
・ Please avoid the water, chemical solvent, or oil.
・ Please avoid the corrosive gas (Cl2 H2S, NH3 NO2, NO3 etc.)
・ Please avoid the strong vibration or shock.
7-4
Mounting
・ Please mount this product under standard reflow condition. Otherwise this product may be
damaged.
・ Please do not apply excessive load to the terminals. Also, please do not bend the ter
・
minals.
Please do not apply excessive bending stress to the product by bending the PCB or
by similar handling as it may change the sensor sensitivity.
