Cognex 3D-A5000 Sensors
Cognex 3D-A5000 sensors combine structured light projection and GigE Vision cameras to generate information about
three-dimensional objects. The sensor projects a pattern on an area within the field of view of two enclosed cameras:
Cognex software builds a 3D data structure representing the object from geometrically distorted images taken from the
two cameras, which can then be viewed as a static 2D image or dynamically through a 3D viewing option:
Once you have the 3D data, VisionPro supports a variety of 3D vision tools for performing tasks such as:
lFinding the 3D pose of a trained 3D model
lGenerating height or volume calculations
lAnalyzing a cross-section of the object
See your installed VisionPro documentation for details.

Hardware Installation
Cognex ships your 3D-A5000 sensor with a power supply and cables for the GigE Vision cameras and I/O connections.
See the section PC Requirements on page6 for the minimum PC requirements to use with your 3D-A5000 sensor.
Be aware you need the following accessories to complete the installation of your PC and 3D-A5000 series sensor:
lA 1024 x 768 display at 96 DPI
lAny network cables to connect your PC to your corporate network
lA VisionPro security key.
The security key provides a security mechanism to ensure that the Cognex software is properly licensed.
l(Optional)Hardware trigger
lA mounting option for your 3D-A5000 sensor.
Refer to the following diagram for physical dimensions (in mm)of the mounting options on the back of the sensor:
Precautions
To reduce the risk of injury or equipment damage, observe the following precautions when you install the Cognex
product:
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.
lChanges or modifications not expressly approved by the party responsible for regulatory compliance could void
the user’s authority to operate the equipment.
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.
lThis device is certified for office use only and if used at home, there can be frequency interference problems.
lThis device should be used in accordance with the instructions in this manual. Failure to do so may impair the
performance and/or protection provided by the device.
lAll specifications are for reference purposes only and can change without notice.

Green (Ethernet) Yellow (Ethernet) Red Green Details
N/A N/A ON FLASH System Error
See the following description.
In the event of a system error, the Green LED fast flashes "N" times, has a long pause, and repeats. The "N"value
indicates the error code:
1. File System Corrupt
2. No Calibration File Present
3. Cooling Fan Failure
4. Diarotator Motor Failure
5. Diarotator Controller Failure
6. Image Sensor Failure
7. Configuration EEPROM corrupt
If the 3D sensor detects multiple errors, each error is flashed with a pause between each value. For example, for errors 2,
3 and 5 the sequence would be:
l2 fast flashes and a short pause
l3 fast flashes and a short pause
l5 fast flashes and a long pause
Then the cycle would repeat.
Caution Labels
Your 3D-A5000 sensor supports a caution label applied to the side of the sensor:
The label contains the following caution:
Do not stare into operating projector. The intense light may be harmful to the eyes.
Depending on how your mount the hardware in your production environment, the caution label might not be visible to
anyone operating the sensor. Find additional English and non-English labels in the packaging with your Cognex
hardware.
11
Hardware Installation

Use the non English label if the English label is not sufficient for your production environment. Place one or both labels
in a place visible to anyone operating the sensor:

1 READY+ Yellow
2 Reserved White/Yellow
3 Reserved Brown
4 READY- White/Brown

9 TRIGGER_OUT+ Green
10 TRIGGER_OUT- Orange
11 MISSED_TRIGGER+ Blue
12 MISSED_TRIGGER- Grey
Hardware Triggers
The acquisition trigger input to the 3D sensor is opto-isolated, and the sensor will respond to a trigger event when the
voltage difference between the TRIGGER+ and TRIGGER- inputs exceeds 10V.
Specification Description
VIH ±10 – ±28 V
VIL 0 – ±5 V
ITYPE @ 12 VDC, 4 mA
@ 24 VDC, 8 mA
Delay 50 µs maximum latency between leading edge of trigger and start of acquisition. Input pulse
should be a minimum of 1ms wide.
Trigger Circuit
30V max across the input pins - transition approx. 10V (Min.)
13
I/O Cable

To configure the acquisition trigger as a sourcing input, connect the TRIGGER+ terminal to the high-voltage reference
(24VDC) and the TRIGGER- terminal to the output of the photo-electric sensor.
Trigger (Source)
To configure the acquisition trigger as a sinking input, connect the TRIGGER- terminal to the low voltage reference
(ground) and the TRIGGER+ terminal to the output of the photo-detector or PLC.
Trigger (Sink)
Be aware of the following I/O line behavior during acquisition:
lThe sensor asserts the READY line to indicate that it will perform a hardware-triggered acquisition when it detects
a rising edge on the TRIGGER_IN line.
The sensor must be configured for hardware triggers, an acquisition start command received, and the sensor
must not be currently performing an acquisition.
lThe sensor generates a 5.2 ms pulse on the TRIGGER_OUT line at the start of any acquisition sequence
(hardware trigger or software trigger)
lThe sensor generates a 5.2 ms pulse on the MISSED_TRIGGER line if it detects a TRIGGER_IN signal but the
READY line is not asserted
Discrete Outputs
See the topic Hardware Triggers on page13 for details on the acquisition trigger. Your 3D-A5000 sensor supports three
other optically-isolated high-speed outputs that can be used as either NPN (current sinking) or PNP (current sourcing)
lines.
Specification Description
Voltage 26.4VDC maximum through external load
Current 50mA maximum sink current
OFF state leakage current 100µA
External load resistance 240 Ohms to 10K Ohms
Each line rated at a maximum 50mA, protected against over-current, short circuits and transients
from switching inductive loads. High current inductive loads require an external protection diode.
Delay210µs (maximum due to opto-isolators turning on)
See the topic I/O Cable on page13 for the pin assignments of the 3D-A5000 sensor I/O cable.
Your 3D-A5000 sensor uses an identical circuit for all the outputs the 3D sensor supports:

Cleaning and Handling
Cognex makes the following recommendations for cleaning your 3D-A5000 sensor.
To clean the outside of the 3D sensor housing, use a small amount of mild detergent cleaner or isopropyl alcohol on a
cleaning cloth. Do not pour the cleaner directly onto the 3D sensor housing.
CAUTION: Do not attempt to clean any Cognex product with harsh or corrosive solvents, including lye, methyl ethyl
ketone (MEK) or gasoline.
To remove dust from the camera windows, use a pressurized air duster. The air must be free of oil, moisture or other
contaminants that could remain on the windows. To clean the window, use a small amount of isopropyl alcohol on a
cleaning cloth and gently clean the window surface. Do not scratch the windows. Do not pour the alcohol directly on the
windows.
