Photoelectric Sensors Technical Guide

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.

(2) Removing Fibers

Open the protective cover, lift up the lock lever, and pull out the fibers.

● Adjustments

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.

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.

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.
