Applications

E39-F10 Fiber Connector

Use the following procedure (refer to the figure) to connect fibers via

the Fiber Connector.

Splice

Retention Unit

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.

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

tached nut.

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.

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)

A: The focus is farther than the E39-F3A.

B: The focus is closer than the E39-F3A

E39-G3 Sensitivity Adjustor

1. Remove the cover of the E3X.

2. Attach the E39-G3 (refer to the figure).

Cover

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).
