Optical Axis Adjustment - Omron E3X-NA Manual

Securing Fibers
The E3X Fiber Unit uses a one-touch locking mechanism. Use the
following methods to attach and remove Fiber Units.
(1) Attaching Fibers
Open the protective cover, insert the fiber up to the insertion mark on
the side of the Fiber Unit, and then lower the lock lever.

Optical Axis Adjustment

Move the Photoelectric Sensor both vertically and horizontally and set
it in the center of the range in which the operation indicator is lit or not
lit. For the E3S-C, the optical axis and the mechanical axis are the
same, so the optical axis can be easily adjusted by aligning the
mechanical axis.

Note:1.To maintain the fiber characteristics, make sure that the lock
is released before removing the fibers.
2. Lock and unlock the fibers at an ambient temperature of

10 to 40°C.
Optical axis: The axis from the center of the lens to the center of
the beam for the Emitter and the axis from the
center of the lens to the center of the reception area
for the Receiver.
Mechanical axis: The axis perpendicular to the center of the lens.
