Installation Orientation
The figure below illustrates a front view of the EM3080-W after installation, with the engine
’s decoder
board on the top, and illumination and lens on the front. The EM3080-W installed in this manner allows its
lens to be seen from the outside.
Optics
Window Placement
The window should be positioned properly to let the illumination beam pass through as much as possible
and no reflections back into the engine (reflections can degrade the reading performance).
The window should be mounted close to the front of the engine (parallel). The maximum distance is
measured from the front of the engine housing to the farthest surface of the window. In order to reach
better reading performance, the distance from the front of the engine housing to the furthest surface of the
window should not exceed 3mm and the distance from the front of the engine housing to the nearest
surface of the window should not exceed 2mm.
If the window is required to be in a tilted position, the above distance requirements should be met and tilt
angle should ensure no reflections back into the lens.
