GUIDELINES FOR USAGE
Handling
As indicated on the previous page, the absolute maximum
rating of the built-in photo-interrupter is 25°C.
In the enent that a voltage or current that exceeds the
maximum rating is applied to, or passed between the
terminals, the photointerrupter
will no longer function normally. In such a case, do not reuse
the photo-interrupter but discard it.
Be careful not to apply an excessively large load to the
terminals because this may damage the photo-interrupter.
Soldering
Perform soldering in less than 3 seconds with maximum
350°C iron. Care should be taken not to apply force to the
terminals during soldering. We recommend a soldering iron
with temperature adjustment in order to prevent poor quality
soldering.
Please consult us if you intend to use a soldering iron of 60 W
or higher.
Environment
This product is a non-contact type tip detection switch
containing a photo-interrupter.
It is intended for installation in equipment. Because of the
nature of a semiconductor, if this product is used continuously
for a long period in a high temperature, low temperature
and/or humid environment, according to the optic quantities
decrease of luminescent diode output characteristics may be
significantly affected. In such a case, take suitable measures,
such as inserting a comparator at the output side, to provide a
greater degree of margin with respect to change in the output
characteristics, and thereby improve the reliability of the
product.
Also, since it is not a sealed type (waterproof construction),
please provide a sealed construction for the entire product if it
will be used in a place where water might get splashed on it or
in an environment with the possibility of condensation.
Also, if sealing with a sealant for PC boards, please make sure
to evaluate and confirm that no sealant enters the inside of the
unit.
Preventing a malfunction
The TiP sensor uses an internal sphere, hence chattering
occurs if it is subjected to vibration or shock. To prevent
chattering, continuously read pulses of 30 ms max. using a
microprocessor, and set the microprocessor so that the switch
goes L(ON) or H (OFF) if the output level exceeds500 ms
continuously. Also, take steps to keep induction and RF noise
away from the sensor. The switch should be mounted keeping
away from the vibration generator such as motor. Fix the PC
board firmly in order to prevent resonance with the vibration
generator, or the contact chattering of a switch may occur by
the movement of a ball inside.
The allowable vibration level which the chattering does not
occur would be less than 2.94m/s
2
at 10 to 400Hz. (The range
260 to 320Hz may have a resonance point and the level
should be less than 0.98m/s
2
.)

Others
1) Depending on usage conditions and environment, solder
migration may occur and short a circuit. Please confirm
that the insulation distance is large enough in the actual
application.
2) To prevent a malfunction, the switch should be kept away
from the direct sunlight and any other light sources.
3) The noises caused by electrostatics, surge voltage and
inductives may break the photo-interruptor.
4) The reflow soldering and cleaning are not allowed.
5) The switch should be mounted with the tolerance ±3
degree.
Confirmations in the actual use.
Each items in this spec sheet was tested and confirmed
independently at a certain duration. To get a higher reliability
of the equipment, please confirm the switch quality with the
actual load and environmental conditions before using.
