If you are using an SUS

bracket, thread a welded M4

stud bolt through the hole on

the bracket and attach an M4

nut (not included with this

product).

If you are using a PVC bracket,

glue it to the mounting surface

such that the side with “TOP”

etched into it is facing up and

glue it within the welding area

as shown in the diagram on the

right.

Slide the male part of the

bracket attached to the steel

case into the female part on the

fiber until you hear them click.

(NF-TH12/-TH13/-TH14/-TH15/-TH16)

Mounting Narrow Beam/Wafer Mapping

Fibers (NF-TG01/-TG02/-TG03/-TG04)

When not using brackets

Use cup-point set screws (M3

or smaller) for mounting within

15mm of the tip of the head

as shown in the diagram to

the right.

To connect heat-resistant joint fibers to NF-TB09,

follow the instructions below.

Keep the heat-resistant joint fiber at least 100mm

from the boundary of the ordinary-temperature side in

order to protect NF-TB09 and amplifiers.

Through beam Type

As shown in the diagram below, determine a refer-

ence plane, make sure the optical axis is aligned

properly, and mount the receiving and emitting fibers

so that they are parallel to the reference plane.

Please take care when mounting this product

because its aperture angle is extremely small, and

there are cases where the fibers do not transmit light

because of the way they were mounted.

To mount the parts that connect the heat-resistant

joint fiber and NF-TB09 to the mounting plate with

metal nuts, follow the instructions below.

The mounting plate thickness needs to be 1mm or

thinner.

Instructions

NF-TG01

NF-TG02/-TG03/-TG04

①

Attach the plastic nut that comes with the heat-

resistant fiber and spring washer to the tip of

NF-TB09, pushing them back as far as they will

go.

②

Attach the heat-resistant joint fiber to the

NB-TB09 with a locknut.

③

Screw up the plastic nut against the locknut so

that it will not loosen.

Instructions

①

Remove the protective tube from NF-TB09, attach

the metal nut to the tip of the fiber and move it

down to the fiber part.

②

Insert the tip of the fiber through the mounting

plate.

③

Follow the instructions from <Connecting heat-

resistant joint fibers to NF-TB09> to connect the

heat-resistant joint fiber to NF-TB09.

④

Tighten the metal nut from the first step of these

instructions against the mounting plate.

Use 1.6mm M1.4 screws to

mount the fiber head and reflec-

tor to the mounting plate as

shown in the diagram on the

right. The mounting plate needs

to have a thickness of 0.9mm or

thinner.

Use a thread lock compound to

tighten screws when mounting

them in places with vibrations or

shocks.

Attach the parts so that the

holes for the fiber head and

reflector are parallel to one

another and such that parts A,

B and C are each parallel as

shown in the diagrams below.

Use zip ties and anti-slip tubes to mount the clamp to

the pipe as shown in the diagram below.

Use two zip ties on the upper and lower part of the

clamp to attach it securely to the pipe. Cut off the

extra part of the zip ties that stick out.

Use zip ties and anti-slip tubes to mount the clamp to

the pipe as shown in the diagram below. Make sure

that the positioning lever is in the closed position as

shown below when you mount the clamp. Use two

zip ties on the upper and lower part of the clamp to

attach it securely to the pipe. Cut off the extra part of

the zip ties that stick out.

We recommend using zip ties of a thickness 2.5mm

or smaller as shown in the diagram below.

You must use M3 screws, plain washers and spring

washers when using the holes for mounting.

(These parts are not included with this product)

You can easily readjust the attachment position when

using zip ties to mount this product.

We recommend using zip ties of a thickness 2.5mm

or smaller as shown in the diagram below.
