Precautions for Correct Use

Fiber Units

This product is not designed or rated for

ensuring safety of persons either directly

or indirectly.

Do not use it for such purposes.

Do not use the Fiber Unit in atmospheres or environments that

exceed product ratings.

• Mounting

Tightening Force

Refer to pages 58 to 61 for the tightening torque to apply when

mounting a Fiber Unit.

Accessories

Use of E39-R3 Reflector Provided with E32-R21

1. Use detergent to remove any dust or oil from the surfaces

where tape is applied. Adhesive tape will not be attached

properly if oil or dust remains on the surface.

2. The E39-R3 cannot be used in areas that are exposed to oil

or chemicals.

Mounting method of Disconnection-resistant

Protective Spiral Tubes (E39-F32

1.Insert the Fiber Unit into the

Protective Spiral Tube from the

head connector (threaded).

2. Push the fiber into the Protective

Spiral Tube. The tube must be

straight so that the fiber enters

without twisting. Turn the Protective

Spiral Tube, not the fiber.

3. Secure the Protective Spiral Tube

to the mounting panel with the

provided nuts.

Attaching the E39-F10 Fiber Connector

Attach the Fiber Connecter as shown in the following figures.

1.Insert the Fiber Unit in the retention clip.

2.Insert the retention clip into the splice.

4.Use the provided saddle to secure

the end cap of the Protective Spiral

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.)

Chemical and Oil-resistant, Liquid-level Detection Fiber Unit

(E32-D82F1)

Fluororesin shows strong chemical-resistant properties but is

permeable if exposed to atmospheres with gaseous chemicals or

water vapors, resulting in failure or damage.

Confirm applicability sufficiently before using the Fiber Unit in

these environments.

• The Fiber Units should be as close as possible when they are

connected.

The sensing distance is reduced by approximately 25% when

Fiber Units are extended by the connector.

• Only 2.2-mm-diameter fibers can be connected.

Connections

• Do not subject the Fiber Unit to excessive force, such as tension

or compression.

Refer to pages 58 to 61 for tensile strengths.

• Make sure any bend in the Fiber Unit is larger than the allowable

bending radius.

Refer to pages 58 to 61 for bending radius ratings and length of

unbendable sections at the base of the Fiber Unit.

• Do not compress or place heavy loads on the fibers.

Sleeve Bender (E39-F11)

• The bending radius of the stainless steel tube should be as large

as possible. The smaller the bending radius is, the shorter the

sensing distance will be.

• Insert the tip of the stainless

steel tube in the Sleeve Bender

and slowly bend the tube

along the curve of the Sleeve

Bender.

Heat-resistant Fiber Units (E32-D51(R) and E32-T51(R))

The fibers of these Units cannot be extended using the E39-F10

Fiber Connector.

Liquid-level Detection Fiber Unit (E32-D82F1)

• Secure the Fiber Unit using the unbendable section.

Otherwise, the liquid-level detection position may be displaced.

• For applications in hazardous environments, install the Fiber

Unit in the hazardous environment but install the Amplifier Unit

in a safe environment.

Liquid-level Detection Fiber Units (Tube-mounting Models)

• Make sure that the tube is not deformed when using a band to

secure the Fiber Unit.

E32-T14

These Units may enter the light-ON state if there are reflective

objects at the end of the lenses.

If reflection is a problem, attach the black stickers provided to the

ends of the lenses.

Vacuum-resistant Fiber Units (E32- V)

Although the Flanges, the Fiber Units on the vacuum side, and

the Lens Units have been cleaned, as an extra precaution, clean

these with alcohol before using them in high-vacuum

environments to ensure that they are properly degreased.

To use the provided slit, peel off the

backing sheet, align the slit with the

edges of the sensing surface, and

attach it to the sensing head.

Use the slit in applications where

saturation occurs (i.e., changes in

incident level cannot be detected)

due to short sensing distances.

E32-T16PR

• The method shown below is an effective way to prevent the

Fiber Unit from breaking due to vibration.

The following method is recommended for mounting Fiber Units

with fluororesin-covered sensing heads (E32-T�F and E32-D�F) to

prevent from cracking the fluororesin case.

If you use a set screw to secure the Fiber Unit, tighten it with care

to prevent from cracking the case.

Warning

Detection Position for Liquid-level Detection Fiber Unit

(E32-D82F1)

The liquid-level detection position

is 5.2 ±2 mm from the end of the

fluororesin section. (Refer to the

diagram on the right.)

The liquid-level detection position

varies with the surface tension of

the liquid and the degree of

wetness at the Fiber Unit’s

detection position.

•Adjustment

Liquid-level Detection Fiber Unit (E32-D82F1)

• Operation may become unstable in the following cases:

1. Bubbles stick to the cone of the sensing head.

2. Solute deposits on the cone of the sensing head.

3. The liquid has a high viscosity.

• There are some liquids, such as milky white liquids, for which

detection is not possible.

• Do not let the end of the fluororesin section bump into other

objects.

Damage to or deformation of the sensing head may cause

unstable operation.
