Mechanical mounting
Reduced height
In comparison with the LC 4x3, the height of the scanning unit of the LC 4x5 has been reduced from 25 mm to 13 mm.
It is now equal to the height of the LS 400.
The housing dimensions and the position of the mounting holes of the scanning unit remain identical to the LC 4x3
so that the LC 4x5 can be mounted unaltered to existing geometries.
Compressed-air inlet on the opposite side
The compressed air inlet (D) had to be displaced to the opposite side of the scanning unit as the overall height was
reduced.

Mechanical mounting
The connection for the pressure tubing can be rotated by 180° to its original direc-
tion by means of the adapter piece ID 630380-01.

The adapter piece does not have an integrated throttle. An additional connecting
piece with throttle ID 275239-01 must be used.

Also with adapter, the height of the LC 4x5 scanning unit remains within the dimensions of the LC 4x3; the length of
the scanning unit merely increases by 12 mm.
