Instruction Manual SK12240U3KOC-LB © 2020-03 E
The SK line scan camera series is designed for a wide
range of vision and inspection applications in industrial
and scientific environments. The SK12240U3KOC-LB
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 SK12240U3KOC-LB 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
1) This camera is USB 2.0 downward compatible with the following limitation:
When connected to a USB 2.0 interface, the pixel data transfer rate is limited to 20 MByte/s and the line frequency is
limited accordingly.
2) The maximum power supplied by an USB 3.0 interface is 4.5 Watt. This is sufficient up to a pixel frequency of 60MHz.
When operated at 100 MHz pixel frequency or when connected to an USB2.0 interface an external 5 V DC power supply
unit is required (see section Accessories).
2)

2 Installation and Setup
2.1 Mechanical Installation: Dimensions, Mounting Options, and Heat Dissipation
Casing type AT3L
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-L (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-L. For this purpose, a second mounting
bracket type SK5105-2L 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.
