With counterlighting the Checkbox scans the test part as a shadow in front of a
bright background. The sensor looks directly at the source of light. This arrange
ment is to be recommended if the test part is at a long distance from the sensor or
if it has a shiny surface. Advantages: Recording is not influenced by the surface of
the object; the source of light is used efficiently.
With
direct light the test part is illuminated frontally from the direction of the
Checkbox. Objects which reflect well therefore appear bright on a dark back
ground. Direct light illumination is used mainly in cases where light cannot be
mounted behind the test part.
Electrical connection of the illumination
S
When connecting the illumination please note:
the documentation supplied with the illumination
the instructions on the power supply of external components in the manual
type P.BE−CB−COMP−... .
Please note
Under the following conditions, current−consuming devices can be supplied
with power via pin 4 (GND) and pin 7 (+ 24 V) on the PLC connection.
S
Connect only current−consuming devices which return the complete current
to the CHB−C−... . In this way you can prevent asymmetries of the currents in
the outgoing and return lines from reducing the effect of the filter.
S
Load output pin 7 with maximum 700 mA.
S
Note that the maximum sum current of all outputs must not exceed 1 A.
Setting the recording distance and the lens

It has a standard connection for lenses on CCD cameras, complying with the
CMount standard.
Connecting thread on the lens: Outer thread 1"−32UN−2A
Support mass of 17.5 mm
