Digital Linescan Camera
Data and Power
Connectors (cont.)
Parallel LVDS (RS-644) Models:
The communications connector on the 
LD3500 is a MDR36 (mini-D-shell) 
connector.  This 36 pin connector 
provides all communications and 
controls needed for camera operation.
Power is provided to the LD3500 via a 6 
pin, Hirose HR10A circular jack.
Refer to Table 1b for pinout of the 
communications and control connector.  
Figure 2 provides pinout locations for 
this connector
Camera Construction
The camera head is housed in a rugged, 
one piece deep drawn aluminum case, 
measuring 2.5" H x 2.5" W x 3.2" L 
(excluding lens mounts or connector 
extensions) specifically designed for 
industrial applications.   The sensor is 
mounted on an aluminum plate that 
efficiently transfers heat to the camera 
case. The camera is provided with a 
standard 1/4"-20 UNC tripod mounting 
block, which can be attached to any of the 
four sides of the camera. The mounting 
holes used to attach the tripod block can 
also be used to mount the camera 
assembly. Additionally, the CCD sensor is 
thermally coupled to the faceplate of the 
camera, and the conductive cooling of this 
surface is useful in minimizing thermally 
generated dark current and noise of the 
camera system.

Optical Interface
The LD3500-series cameras are equipped 
with a U-Mount lens interface (MA2-1-
6H) that is aligned to the CCD sensor.  
These standard adapters allow the user to 
select the optimum lens to suit their 
particular application.
