pixel 1024. This dark offset allows the
user to adjust the standard 0 V signal
±100 mV.
Additionally, the LC1917 camera
features a user-adjustable video gain,
allowing for video gains of up to 2.5X.
Video gain is adjustable using the
potentiometer, located underneath the
set screw on the body side adjacent to
the active pixel 1 side of the camera.
Both the gain and offset potentiometers
can also be adjusted by removing the
bottom plate of the camera. This is
accomplished by removing the two
lower screws on both the faceplate
and rear body of the camera. The cam-
era bottom is not attached to any
internal circuitry.
Proper ESD precautions should be
taken when removing the bottom plate
of the camera. Failure to do so can
result in camera failure.
User Connections
The connector on the LC1917-series
camera is a 26-pin high density male
AMP C-216297. All user connections
are via this connector. It contains all
communications, output, and power
connections needed for camera opera-
tion. Refer to Table 1 for pinout locations
and details. Connector pin locations
are shown in Figure 4.
Optical Interface and Mounting
The LC1917 is to be mounted to the
user’s optics via 4 M3 threaded screws,
located on the front panel of the
camera, adjacent to the sensor.
The optical surface of the sensor is
located 2.7mm (±10%) from the surface
face of the camera. The sensor has a
maximum angular error of ±15
milliradians.
Camera Performance
The camera head is housed in a
rugged aluminum case, measuring
0.75”H x 2”W x 3.077”L (excluding
connector extensions) specifically
designed for close-proximity harsh
industrial applications. The sensor is
mounted on an aluminum plate that
efficiently transfers heat to the camera
case. The conductive cooling of this
surface is useful in minimizing ther-
mally generated dark current and
noise of the camera system.
