Applications
E39-F10 Fiber Connector
Use the following procedure (refer to the figure) to connect fibers via
the Fiber Connector.

Retention Unit
E39-F3A Reflective Unit Lens
When the E39-F3A is attached to the fiber, the E3X can sense the
light reflected from the interior of the E39-F3A. If this happens, ad-
just the sensitivity of the E3X Amplifier with Sensitivity Adjustor.
Place a sensing object or white paper at the sensing distance set
and adjust the insertion length of the Fiber Unit to the E39-F3A so
that the light spot is as small as possible. Then fix the position of the
Fiber Unit with the hexagonal wrench (attachment)
Tighten
Each fiber should be as close as possible before they are con-
nected.
Sensing distance will be reduced by approximately 25% when fibers
are connected.
Only fibers with 2.2 mm dia. can be connected.
Protective Spiral Tube
Insert a fiber to the Protective Spiral Tube from the head connector
side (screwed) of the tube.

Fiber Unit
Push the fiber into the Protective Spiral Tube. The tube should be
straight so that the fiber is not twisted when inserted. Then turn the
end cap of the spiral tube.

1. Remove the cover of the E3X.
2. Attach the E39-G3 (refer to the figure).

Secure the Protective Spiral Tube on a suitable place with the at-
tached nut.

3. After the cover is attached to the case, turn the knob of the
E39-F3A clockwise or counterclockwise once. To confirm
that the knob has been set properly, turn the knob clockwise
or counterclockwise until you hear a click (8 turns max. are
necessary).
Note: E3X looses watertightness if E39-G3 is attached (the en-
closure rating will be IP50).

Use the attached saddle to secure the end cap of the Protective Spi-
ral Tube. To secure the Protective Spiral Tube at a position other
than the end cap, apply tape to the tube so that the portion becomes
thicker in diameter.
