MultiSight ™ Vision Sensor
The Economical Alternative to High-End Vision Systems
The A-B MultiSight is an optical multipixel
sensor with a pass/fail PNP output
that is ideal for error-proofing and inspection
applications. The MultiSight uses
three different methods of evaluation (pattern
matching, contrast, and brightness) to
detect or differentiate objects by means of
previously defined optical characteristics,
e.g. for separating “good” and “bad” parts.
The main applications are in the field of
industrial automation for quality assurance
purposes. The MultiSight is an easy-to-use
economical alternative to conventional
vision systems for detecting presence or
absence, completeness, position, markings,
labeling, packaging, and components.
The latest MultiSight model is an
Detection of Aerosol
Can Nozzle and Label
In this application, two virtual detectors are configured
and then logically linked together to generate
one pass/fail output. The MultiSight detects the
presence of both the nozzle and the label. The
first virtual detector is configured with a detector
type of Pattern Matching to detect the nozzle. The
second detector uses a detector type of Brightness
to detect the presence of the label. The MultiSight
performs an AND function on the results of the two
detectors and generates a single pass/fail output.
EtherNet/IP version. This new development
maximizes the capability of the new
MultiSight Vision Sensor by making the
entire sensor’s analytical data available on
the network for detailed product inspection
information. An Add-On Profile for an Allen-Bradley
Logix PLC program will create
predefined tag names for inspection values,
position information, and the results of
multiple virtual detectors. The Ethernet/IP
model includes more virtual detectors - 32
in total - to maximize the number of locally
stored configurations. This model also
includes a new Contour algorithm with
full 360-degree rotational compensation,
allowing the detection of a line contour in
any orientation.
Features:
• Stand-alone vision sensor
• Easy handling and setup
• Compact, sturdy industrial housing
with IP67 rating
• Integrated lighting
• Adjustable focus from 20 mm to
infinity
• Short evaluation time (50-100ms)
• 3 evaluation methods: Pattern
Matching, Brightness, and Contrast
• 32 virtual detectors
Application Examples
Verification of
Date Code Printing
Here the MultiSight verifies that a date code has
been printed by using a Contrast detector type. When
the date code is printed, the contrast is high. When
it is not printed, the contrast is low. The MultiSight
detects the difference between the contrast levels to
determine if the date code has been printed.

• by Chuck McLamb
• Individual virtual detectors can be
logically linked or grouped for evaluation
of different objects with several
characteristics for inspection
• Ethernet connection for setup
• EtherNet/IP™ models feature an
RSLogix™ 5000 Add-On Profile with
pre-named data tags for simple integration
into a control program
Benefits
• Perform multiple inspections with one
sensor

• Label placement verification
• Print job confirmation
• Part alignment verification
• Missing bottle cap detection
Verification of Tapped
and Threaded Holes
In this application, the MultiSight uses a Pattern
Matching detector type to confirm that the holes
have been tapped and threaded.
