Precautions
To reduce the risk of injury or equipment damage, observe the following
precautions when you install the Cognex product:
lThe safety of any system incorporating this product is the responsibility of
the assembler of the system.
lDo not install Cognex products where they are exposed to environmental
hazards such as excessive heat, dust, moisture, humidity, impact,
vibration, corrosive substances, flammable substances, or static electricity.
lRoute cables and wires away from high-current wiring or high-voltage
power sources to reduce the risk of damage or malfunction from the
following causes: over-voltage, line noise, electrostatic discharge (ESD),
power surges, or other irregularities in the power supply.
lDo not expose the image sensor to laser light. Image sensors can be
damaged by direct, or reflected, laser light. If your application requires
laser light that might strike the image sensor, use a lens filter at the
corresponding laser wavelength. For suggestions, contact your local
integrator or application engineer.
lThis product does not contain user-serviceable parts. Do not make
electrical or mechanical modifications to product components.
Unauthorized modifications can void your warranty.
lChanges or modifications not expressly approved by the party responsible
for regulatory compliance could void the user’s authority to operate the
equipment.
lInclude service loops with cable connections.
2

lEnsure that the cable bend radius begins at least six inches from the
connector. Cable shielding can be degraded or cables can be damaged or
wear out faster if a service loop or bend radius is tighter than 10X the cable
diameter.
lThis device should be used in accordance with the instructions in this
manual.
lAll specifications are for reference purposes only and can change without
notice.

Mounting the Vision Sensor
CAUTION:The vision sensor has to be grounded, either by mounting the
vision sensor to a fixture that is electrically grounded or by attaching a wire
from the vision sensor’s mounting fixture to frame ground or Earth ground. If a
ground wire is used, it has to be attached to one of the mounting points on the
bottom plate of the vision sensor and not to the mounting points on the front of
the vision sensor.
1. Align the vision sensor with the holes on the universal mounting bracket.
16

2. Insert the screws.
Note: The vision sensor has two sets of threaded holes for mounting.
Use only one set depending on the best configuration for your
application. For the threaded holes closer to the front of the vision
sensor you need M3X5 screws, for those closer to the connectors
M3X9.
17

3. If needed, you can rotate the mounting bracket up to 45 degrees. To do so,
loosen the screw in the curved slot.
Note:
Mounting the vision sensor at a slight, 15 degree angle reduces reflections
and improves performance.
18

Connecting the Ethernet Cable
CAUTION:The Ethernet cable shield has to be grounded at the far end.
Whatever this cable is plugged into (typically a switch or router) should have a
grounded Ethernet connector. A digital voltmeter has to be used to validate
the grounding. If the far end device is not grounded, a ground wire should be
added in compliance with local electrical codes.
1. Connect the Ethernet cable's M12 connector to the vision sensor ENET
connector.
2. Connect the Ethernet cable’s RJ-45 connector to a switch/router or PC, as
applicable.
Note: Besides powering the vision sensor through a Breakout Cable, it is
possible to power through PoE (Power over Ethernet) connection as well, in
which case it is not necessary to use a Breakout Cable.
In-Sight SnAPP configurations support PoE connection.
19

Connecting the Power and I/OBreakout Cable
CAUTION:To reduce emissions, connect the far end of the Breakout cable
shield to frame ground.
Note:
lPerform wiring or adjustments to I/O devices when the vision sensor
is not receiving power.
lYou can clip unused wires short or use a tie made of non-conductive
material to tie them back. Keep bare wires separated from the +24 V
DC wire.
1. Verify that the 24 V DC power supply is unplugged and not receiving
power.
2. Attach the +24 V DC connector of the Power and I/O Breakout cable and
Ground wires to the corresponding terminals on the power supply. For
more information, see Specifications on page24.
3. Attach the M12 connector of the Power and I/O Breakout Cable to the 24 V
DC connector of the vision sensor.
4. Restore power to the 24 V DC power supply and turn it on if necessary.
