Banner PresencePLUS PPM8 LCD Color Monitor - Manual (Page 4)

1. Sensor: The sensor contains the imager, microprocessor and
I/O. The imager has an array of tiny light-sensitive cells (pixels)
that convert the target into an image. The microprocessor
analyzes the image and makes determinations about it based
on user-determined tolerances and criteria. The sensor
exports the inspection results through some type of I/O,
such as discrete, Ethernet or serial.
2. Lens: The lens focuses the light onto the sensor’s
imager. To determine the lens focal length for an
applications, specify the field of view and
working distance.
3. Light Source: The light source is a critical
component of any vision inspection system. Lighting is
the most powerful tool for creating contrast to amplify
the feature of interest, while minimizing other features of the
part. Selecting the best light source depends on the shape,
surface texture, color and opacity of the part.
Vision sensing from the source you trust.
As the prefered brand of sensors worldwide, Banner
knows the challenges of the factory floor. That’s why we
designed our line of PresencePLUS® vision sensors from
the ground up, with advanced features, easier setup and
operation, rugged design, the most value of any vision
systems in the market and, most of all, Banner reliability
and support.
A complete solution.
From a single inspection point to plant-wide vision
integration, Banner offers complete vision solutions. Vision
sensing has two major elements: hardware—the camera,
controller, lighting and brackets; and software— the control
system, graphical user interface and image algorithms.
Banner provides all of the elements to successfully deploy
vision sensing in your facility.
Visual Inspection Process
1. Acquire an image of the part.
2. Analyze the image.
3. Determine if the inspection passes or fails, and report the
results to the manufacturing line. The part then either passes
to the next process or is rejected and removed. Opposed Mode Proximity Mode
