CE
This section describes a summary of precautions when bringing into CE conformance the machinery formed by using the
vision sensor.
Note that the descriptive content is material created based on regulation requirements and standards obtained by Mitsubishi
Electric Corporation. However, machinery manufactured in accordance with this content is not necessarily guaranteed to
conform with the above commands.
Final judgment regarding CE conformance or the method of conformance must be the judgment of the machinery
manufacturer itself.
To meet the CE compliant conditions, implement the following items.
• Significant amount of noise on the power source may cause malfunction. Use a regulated DC power supply with an
isolating transformer for the power supply. Additionally, install a noise filter (SNR-10-223 by COSEL or an equivalent
product) between the vision sensor and the regulated DC power supply.
Precautions
Ground the FG terminal with the ground cable as short as possible (with the length of 30 cm or shorter).
• EMC application

SAFETY PRECAUTIONS
(Read these precautions before using this product.)
Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle
the product correctly.
The precautions given in this manual are concerned with this product only. For the safety precautions for other modules, refer
to their respective user's manuals.
In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".
Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to serious
consequences.
Observe the precautions of both levels because they are important for personal and system safety.
Make sure that the end users read this manual and then keep the manual in a safe place for future reference.
[Installation Precautions]
[Installation Precautions]
[Wiring Precautions]
WARNING
●Before touching the vision sensor, be sure to touch an electric conductor such as grounded metal to
discharge the static electricity from your body. Otherwise, damage or faulty operation of the vision
sensor may occur.
●Be sure to install an I/O connector module to the main module. If not installed, dust or water-proof
performance may not be obtained.
CAUTION
●IP protection rating is guaranteed only when all the connectors are connected with cables or sealed
with sealing caps.
●The cable is designed to connect with its key aligned with the keyway of the connector on the Vision
Sensor. Do not force the connections or damage may occur.
CAUTION
●Use only 24 V DC and observe the indicated polarity. Otherwise, fire or damage may result.
●The frame ground terminal of the I/O module and the shield ground of each connector (RS232 OUT
port and SENSOR port) are internally conducting. The system ground is designed on the condition
that a ground connection is provided. The ground potential may affect the vision sensor and
peripheral devices such as programmable controllers via cables. For safe operation, it is
recommended to connect all the ground connections securely.
WARNING Indicates that incorrect handling may cause hazardous conditions, resulting in
death or severe injury.
CAUTION Indicates that incorrect handling may cause hazardous conditions, resulting in
minor or moderate injury or property damage.

[Startup and Maintenance Precautions]
PRECAUTIONS FOR USE
Observe the following precautions when installing and operating the vision sensor, to avoid the risk of injury or equipment
damage:
• The power for a vision sensor is intended to be supplied by UL or NRTL approved power supply with a lowest rated output
voltage of 24 V DC with at least 2 A of current, a maximum short circuit current rating of less than 8 A, a maximum power
rating of less than 100 VA, and marked Class 2 or LPS (Limited Power Source).
Any other voltage creates a risk of fire or shock and can damage the components.
Applicable national and local wiring standards and rules must be followed.
• To reduce the risk of damage or malfunction due to over-voltage, line noise, electrostatic discharge (ESD), power surges, or
other irregularities in the power supply, route all cables away from high-voltage power sources.
• Do not install the vision sensor where they are directly exposed to environmental hazards such as excessive heat, dust,
moisture, humidity, impact, vibration, corrosive substances, flammable substances, or static electricity.
• Do not expose an image sensor to laser light; image sensors can be damaged by direct or reflected laser light.
If your application requires the use of laser light that may strike the image sensor, a lens filter at the corresponding laser's
wavelength is recommended.
Consult your local system integrator or application engineer for suggestions.
• A vision sensor does not contain user-serviceable parts. Do not make electrical or mechanical modifications to a vision
sensor.
Any modification may void your warranty.
• Changes or modifications not expressly approved by the party responsible for regulatory compliance could void the user’s
authority to operate the equipment.
• Service loops (extra wire length) should be included with all cable connections.
• If the bend radius or service loop is smaller than 10 times of the cable diameter, the cable may cause cable shielding
degradation, cable damage, or wear out in a short period.
The bend radius must begin at least 152.4 mm from the connector.
• This equipment is a Class A device. Using this equipment in a domestic environment may cause radio disturbance. In this
case, the user may be required to take appropriate measures.
• If there is concern about noise, set a noise filter (SNR-10-223, COSEL or an equivalent) between the vision sensor and the
stabilized DC power supply.
• To maintain the safety of the system against unauthorized access from external devices via the network, take appropriate
measures.
To maintain the safety of the system against unauthorized access from external devices via the Internet, take measures
such as installing a firewall.
CAUTION
●Do not clean the vision sensor with highly irritating or corrosive solvent such as caustic alkali solution,
methyl ethyl ketone (MEK), and gasoline. Doing so may cause a fault.

This chapter shows the specifications of vision sensor VS70s.
3.1 General Specifications
The following shows the general specifications of vision sensor VS70s.
*1 Case temperature can be confirmed using EV GetSystemConfig ("Internal.Temperature") Extended Native Mode command.
When the command is issued, it will return the internal temperature of a vision sensor in degrees Celsius.
The returned temperature will be ±5 degrees of the case temperature of a vision sensor.
For details on the command, refer to the help of In-Sight Explorer.
*2 Additional cooling measures are required if the case temperature exceeds 50.
Examples of such measures include:
⋅Attach an extra heat sink to a vision sensor using M3 screws.
⋅Lower the ambient temperature so that air can pass through a vision sensor.
*3 A vision sensor should be used in the environment where the temperature around the vision sensor is about 0 to 40because the case
temperature is easily influenced by the environment the vision sensor is installed in.
*4 Do not install vision sensors in the following environments:
⋅Where the ambient temperature or humidity exceed the applicable ranges
⋅Where condensation occurs due to sudden temperature changes
⋅Where there is corrosive or flammable gas
⋅Where there are a lot of conductible dust, iron filings, or salt
⋅Where in danger of organic solvents, such as benzene, thinner, and alcohol or strong alkaline substances such as caustic soda to
adhere
⋅Where subject to much vibration or shock
⋅Where in danger of liquid such as water, oil, or chemicals to adhere

Working distance and field of view
The distance from a lens to an inspection target is referred to as 'working distance', and an area where a vision sensor can
see at that distance is referred to as 'field of view.'
As the working distance increases, so does the field of view.
The following shows the horizontal field of view when an S-mount/M12 lens is attached to a vision sensor VS70.
• VS70M-600-E, VS70M-600-ER, VS70M-600, VS70M-600-R, VS70M-800-E, VS70M-800-ER, VS70M-800, VS70M-800-R
