Fiber Insertion

If the portion from the tip to the insertion mark of the fibers are not

inserted into the Amplifier Unit, the sensing distance will be re-

duced.

Cutting Fiber

Insert a fiber into the Fiber Cutter and determine the length of the

fiber to be cut.

Press down the Fiber Cutter in a single stroke to cut the fiber.

An insertion mark can be placed on the fiber to serve as a reference

when inserting the fiber into the Amplifier. Use the following proce-

dure.

Confirm through the Cutter hole that the fiber is inserted beyond the

insertion mark hole so that the insertion mark is properly indicated,

and then press firmly down on the Cutter.

(1)

Insert the fiber into the Amplifier up to the insertion mark. Proper fi-

ber performance will not be achieved unless the fiber is inserted all

the way to the insertion mark. (This method is applicable to stan-

dard, 2.2-mm-diameter fibers only.)

2.2-dia.

The cutting holes cannot be used twice. If the same hole is used

twice, the cutting face of the fiber will be rough and the sensing dis-

tance will be reduced. Always use an unused hole.

Use either one of the two holes on the right (refer to the following

figure) to cut a thin fiber as follows:

1. An attachment is temporarily fitted to a thin fiber before

shipment.

2. Secure the attachment after adjusting the position of it in the

direction indicated by the arrow.

3. Insert the fiber into the E39-F4 to cut.

4. Finished state (proper cutting state)

Note:

Insert the fiber in the direction indicated by the arrow.

Connection

Do not pull or press the Fiber Units. The Fiber Units have a with-

stand force of 9.8 N (1 kgf) or 29.4 N (3 kgf) (pay utmost attention

because the fibers are thin).

Do not bend the Fiber Units beyond the permissible bending radius.

Do not bend the edge of the Fiber Units (excluding the E32-T

and E32-D

jR).
