The Fiber Head could be break by excessive vibration. To prevent
this, the following is effective:
A one-turn loop can

Bending Radius
E39-F11 Sleeve Bender
The bending radius of the stainless tube should be as large as pos-
sible. The smaller the bending radius becomes, the shorter the
sensing distance will be.
Insert the tip of the stainless tube to the Sleeve Bender and bend the
stainless tube slowly along the curve of the Sleeve Bender (refer to
the figure).

Mounting
Mounting
1. Mount the front part on the mounting bracket (attachment) or
a DIN track.
2. Press the back part onto the mounting bracket or the DIN
track.
Note:
Do not mount the back part onto the mounting bracket or
the DIN track first and then mount the front part on the
mounting bracket or the DIN track, or the mounting strength
of the Amplifier Unit may decrease.

Dismounting
By pressing the Amplifier Unit in direction (3) and lifting the fiber in-
sertion part in direction “4” as shown in the following, the Amplifier
can be dismounted with ease.

In the case of side mounting, attach the mounting bracket on the
Amplifier first, and secure the Amplifier with M3 screws and wash-
ers. The diameter of the washers should be 6 mm max.
