Precautions before use:
1. Dirty Glass Surface:
The glass surface should be kept clean.
Do not wipe the sensor by hand or use in a dust polluted environment. Should the glass
surface become dirty, moisten a cloth with alcohol and wipe the surface gently.
Care should be taken so as not to scratch the surface while wiping it. Any loose dust
lying on the sensor surface can be cleaned using an air gun.
2. Dust and the CIS unit
The unit is housed in an air tight structure to protect it from dust. The side plates should
not be removed or dust may enter the unit. When using the side holes to adjust the sensor,
turn the screws slowly until tight, so as not to damage the screw hole thread.
3. Extracting / Inserting the connector
The maximum number of times that the connector should be extracted and connected is
ten. If the connector is inserted / extracted more than ten times, the connector “burrs”
will be eroded, thereby making the connector ineffective.
4. Stable operation
4.1 The connector pins should not be touched by bare hand or Electro-statically charged
material.
4.2 Noise:
a. Insert a low frequency noise suppressing capacitor (100 μF) between VDD (+5 V)
and Gnd. A high frequency noise suppressing capacitor is already integrated into
the circuit.
b. Ensure that the sensor connecting cables are 30 cm or less in length. The φCP and
Gnd, φSP and Gnd respectively from twisted cable pairs.
4.3 Latch Up
When the voltage is higher than the absolute maximum, “latch up” will cause the
sensor to break, even if the voltage is caused by a surge. If the current varies rapidly
in the external circuit, or if the power is turned off and then on again, ensure that the
voltage on each terminal does not exceed the values indicated in “absolute maximum
rating”.
