Precautions before Use
Installation Environment
Avoid installing the LightPixAE20 in the following locations:
Locations with direct sunlight or environmental temperatures exceeding a range of 0ºC to +40ºC.
Locations with a relative humidity exceeding a range of 35%RH to 85%RH (without dew condensation
at 25ºC)
Locations with a lot of fine particles, iron filings, salt, oily smoke or conductive dusts.
Locations with an atmosphere containing corrosive gases or flammable gases.
Locations where the product can contact oil or chemicals.
Locations near organic solvents (such as benzene, paint thinner, and alcohol) or strongly alkaline
materials (such as ammonia and caustic soda)
Locations within 100mm of high-voltage wires (or devices), power-driven lines (or devices), radios,
transmitters and devices generating large switching surge (be sure to keep more than 100mm space
between the LightPixAE20 and these devices)
Power Supply
Take care not to generate excessive static electricity from the LightPixAE20.
When supplying power to the LightPixAE20, do not commonly use the power source for powering the
device and be sure to install a protection circuit such as a fuse.
Use an insulated power supply unit with a built-in protection circuit. The LightPixAE20 power supply
unit is a non-insulated circuit. Therefore, applying an abnormal voltage might damage the internal
circuit. If you use a power supply unit without a protection circuit, supply power through a protective
device such as a fuse.
About grounding
Do not commonly use the ground with other devices.
Grounding should be as close as the main unit as possible, and keep the distance short.
Noise Countermeasure

3.3 Fixing and Removing the Main Unit
3.3.1 Main Unit
Fixing the main unit on a wall
Use the three holes on a side of the main unit to fix it on a wall.
Avoid installing the main unit as the following figures shown below.
Wrong Examples
15
Installation distance between the main unit and the inspection object
Keep 15 to 220 mm space between the object and the main unit, but the space varies depending on the
product number of the main unit. Since light guides (two red LED lights) are emitted from the LightPixAE20
to the area around the object, adjust the position of the main unit so that the two lights are close (or overlap)
each other.
Proper Too close Too far
(Dim light guides)
Installation angle
If you want to capture a shiny object, the light emitted from white LED may interfere with the object due to
the mirror reflection from it, so slant the main unit.
16
• Disturbance light, of which illumination intensity varies at the time of measurement, negatively
affects the measurement results. Shield the device from any disturbance light.
• The larger the installation angle, the greater the warp generated in the captured mages. This will
lead to mixed measurement results depending on the position of the object within the field of
view. Determine the installation angle of the main unit after actually checking the image.
Conformity to the EMC standard
The AE20 will comply with the EMC standards (EN61000-6-4, EN61000-6-2) in EMC Directive (EMC
Directive 89/336/EEC). The product must fulfill the following conditions:

• To prevent input signal chattering, use a non-contact input (transistor etc.). If chattering occurs, inputs
may be missed or input recognition may be delayed.
• Be careful when using only full-wave rectification (including ripples) power supply for DC input, as it
may cause abnormal operation.
• Current leakage at the input side may not turn input off. In such as case, connect a resistor following
the figure below.
• If Input to the LightPixAE20 is not turned off due to current leakage when 2-line photoelectric sensor (or
proximity sensor) is used, connect a bleeder resistor.
• Even in cases where in-line LEDs such as LED reed switches are connected with an input contact
point, Voltage more than the ON voltage must be applied to the LightPixAE20 input terminal.

3.4.3 Output Signal
Circuit
Output part: PhotoMos relay
The output load should be within the specified range. See the figure shown below.
Notes on Parallel Output
• Leakage current at the time of output signal OFF is less than 100 µA.
• The LightPixAE20 has a low load capacity so that you can connect the LightPixAE20 to a PLC, etc. Do
not connect directly with a device having a high load capacity such as a valve without passing it through
our Power-Photo relay.
• The output circuit contains no built-in fuse. If it is necessary to prevent from burning out the output
circuit in the event of output load short circuit, mount a fuse externally. However, it may not be able to
protect internal elements in the event of short circuit.
