Instruction Manual SK22368U3TOC © 2022-03 E
The SK line scan camera series is designed for a wide
range of vision and inspection applications in industrial
and scientific environments. The SK22368U3TOC is
highly portable and the robustly attached dedicated
connections enable external synchronization of the
camera and the output of data to the USB 3.0 port of
the computer.
The USB 3.0 connection supplies power to the camera
and the camera is hot-pluggable, providing the greatest
degree of flexibility and mobility. The computer does not
require a grabber board, allowing a laptop to be used
when space or weight restrictions are also at a premium.
Once the camera driver and the SkLineScan®program
have been loaded from the SK91USB3-WIN CD then the
camera can be parameterized. The parameters, such
as integration time, synchronization mode or shading
correction, are permanently stored in the camera even
after a power-down or disconnection from the PC.
The oscilloscope display in the SkLineScan®program
can be used to adjust the focus and aperture settings, for
evaluating field-flattening of the lens and for orientation
of the illumination and the sensor, see 3.1 Software:
SkLineScan (p. 10).

1.3 Computer System Requirements
1.4 SK22368U3TOC Line Scan Camera - Specifications
Introduction
The camera must be mounted thermally coupled
so that the acceptable casing temperature is not
exceeded during operation. Therefore applies to the
thermal resistance of the bracket or heat sink:
θamb - θcasing
RthHS ≤
Pcamera
where
RthHS [K/W] = thermal resistance of the bracket or heat
sink
θamb [°C] = ambient temperature
θcasing [°C] = temperature of the camera casing (not
to be confused with the internal camera
temperature that is queried and output
with the request command I32)
Pcamera [W] = camera power consumption
This camera is not USB 2.0 compatible. For operation with an USB 2.0 interface request for a factory-preset pixel frequency
limitation. This will reduce the data transfer rate as well as the power consumption to the USB2.0 specifications.
• Intel Pentium Dual Core or AMD equivalent
• RAM min. 4 GB, depending on the size of acquired
images
• USB 3.0 interface. With a USB 2.0 interface, there
are limitations, see footer.
• High-performance video card, PCIe bus
• Operating Systems:
Windows 7 / 8.1 / 10 (64 or 32-bit) or
Linux kernel 3.13 or higher

2 Installation and Setup
2.1 Mechanical Installation: Dimensions, Mounting Options, and Heat Dissipation
Casing type AT2
Mounting Options
When mounting the camera, pay attention to the
following:
• Mechanical stability to avoid vibrations.
• Good thermal coupling for cooling the housing.
The power consumption and the maximum
housing temperature of the camera are specified
in section 1.4 - Specifications.
The best fixing point of the camera is the collar for the
mounting bracket SK5105 (available as an accessory).
Four threaded holes M3x 6.5 mm provide further
options for customized brackets.
The length and weight of the optics might be beyond
the capability of the standard mounting bracket
SK5105. For this purpose, a second mounting bracket
type SK5105-2 to hold the tube extension ring(s) is
more appropriate.
Optics Handling
• If the camera and the optics are ordered as a kit,
the components are pre-assembled and shipped
as one unit. Keep the protective cap on the lens
until the mechanical installation is finished.
• If you must expose the sensor or lens surface,
ensure the environment is as dust-free as
possible.
• Gently blow off loose particles using clean
compressed air.
• The sensor and lens surfaces can be cleaned with
a soft tissue moistened with water or a water-
based glass cleaner.

3 Camera Control and Performing a Scan
3.1 Software: SkLineScan
This section is a brief introduction to the SkLineScan adjustment and configuration software. A more detailed
description is provided in the separate SkLineScan manual. The pdf is included in the SkLineScan installation
package or is available for download from the Schäfter + Kirchhoff website under http://www.sukhamburg.com/
supporte.html.
Detailed instructions on how to obtain optimal image data and use the data with the Schäfter+Kirchhoff
software package can be found in the SkLineScan Software Manual.
The most common functions of the line scan camera can be controlled by menu items and dialog boxes.
In the "Camera Gain / Offset Control" dialog there is a command line for entering further control commands.
Click on the desktop icon to start the SkLineScan
program.
The SkLineScan program recognizes the connected line
scan cameras automatically. The identified cameras are
shown in the start-up dialog A.
If the SK22368U3TOC camera is identified correctly,
confirm with "OK". The "Signal window" graphicaly
showing the intensity signals of the sensor pixels (oscil-
loscope display) will open. It is responsive in real-time
and the zoom function can be used to highlight an area
of interest. The oscilloscope display is ideally suited
for parameterizing the camera, for evaluating object
illumination, for focussing the image or for aligning the
line scan camera correctly.
