camera(s) into a vision system.
Copyright
Any duplication or reprinting of this documentation, in whole or in part, and the reproduc-
tion of the illustrations even in modied form is permitted only with the written approval of
Baumer. This document is subject to change without notice.
Classicationofthesafetyinstructions
In the User´s Guide, the safety instructions are classied as follows:
Notice
Gives helpful notes on operation or other general recommendations.
Caution
P i ctogram
Indicates a possibly dangerous situation. If the situation is not avoided, slight
or minor injury could result or the device may be damaged.

General safety instructions2.
Observe the the following safety instructions when using the camera to avoid any damage
or injuries.
Caution
A power supply with electrical isolation is required for proper operation of the
camera. Otherwise the device may be damaged.
Caution
Provide adequate dissipation of heat, to ensure that the temperature does
not exceed the spedied temperature (+65 °C /+149 °F).
The surface of the camera may be hot during operation and immediately
after use. Be careful when handling the camera and avoid contact over a
longer period.
Caution
When xing the Camera Link® cable with too much force the screws might
get damaged.
The maximum torque is 2.5 inch lbf [0.3 Nm].
Intended Use3.
The camera is used to capture images that can be transferred over two Camera Link®
interfaces to a PC.
Notice
Use the camera only for its intended purpose! For any use that is not described in the
technical documentation poses dangers and will void the warranty. The risk has to be
borne solely by the unit´s owner.

The quantum efciency characteristics of monochrome (also in NIR) and color matrix sen-
sors for Baumer HXC cameras are displayed in the following graphs. The characteristic
curves for the sensors do not take the characteristics of lenses and light sources without
lters into consideration, but are measured with an AR coated cover glass.

6.2.3 Shutter
All cameras of the HXC series are equipped with a global shutter.

ing sensor with global
shutter

Global shutter means that all pixels of the sensor are reset and afterwards exposed for a
specied interval (texposure).
For each pixel an adjacent storage circuit exists. Once the exposure time elapsed, the
information of a pixel is transferred immediately to its circuit and read out from there.
Due to the fact that photosensitive area gets "lost" by the implementation of the circuit
area, the pixels are equipped with microlenses, which focus the light on the pixel.
Digitization Taps6.2.4
The Truesense sensors, employed in Baumer HXC cameras can be read out up to 16
channels in parallel.
Notice
More channels increase the speed (framerate), but the use of more channels produces
a higher heat generation. Use only the maximum required number of channels!
Notice
Due to sensor characteristics in 12 bit mode only 2 or 4 channels are available.

Timings6.3
Notice
Overlapped mode can be switched off with setting the readout mode to sequential shut-
ter instead of overlapped shutter.
The image acquisition consists of two separate, successively processed components.
Exposing the pixels on the photosensitive surface of the sensor is only the rst part of the
image acquisition. After completion of the rst step, the pixels are read out.
The exposure time (texposure) can be adjusted by the user, however, the time needed for the
readout (treadout) is given by the particular sensor, image format and conguration.
Baumer HXC cameras can be operated with two modes, the Free Running Mode and the
Trigger Mode.
The cameras can be operated non-overlapped*) or overlapped. Depending on the mode
used, and the combination of exposure and readout time:
Non-overlappedOperation OverlappedOperation
Here the time intervals are long enough
to process exposure and readout succes-
sively.
In this operation the exposure of a frame
(n+1) takes place during the readout of
frame (n).

6.3.1 Free Running Mode
In the "Free Running" mode the camera records images permanently and sends them to
the PC. In order to achieve an optimal (with regard to the adjusted exposure time texposure
and image format) the camera is operated overlapped.
In case of exposure times equal to / less than the readout time (texposure ≤ treadout), the maxi-
mum frame rate is provided for the image format used. This is for overlapped mode. For
longer exposure times the frame rate of the camera is reduced. This is for sequential
mode.
