Sensing Band
Note:
Specify length (in meter units) when ordering.
When cleaning with a mop, for example, do not make contact with the Sensing Band.

Connecting the Sensing Band
Bending the Sensing Band
In order to change the direction of the Sensing Band, bend the Sens-
ing Band in one or two places where the core is not exposed.
Note:
Bend the Sensing Band approximately 4 cm (i.e., twice the dis-
tance between places where the core is exposed) away from
places where the Sticker is attached. If the Sensing Band is
bent at places further away than this, the Sensing Band may
come away from the surface.
Stripping and Connecting Terminals
1.
Cut into the Sensing Band approximately 4 to 6 cm in from the
end as shown in the diagram below.
2.
Strip away approximately the last 9 mm of the sheath to expose
the core (SUS line).
3.
To connect to the Terminal Block, push down the top of the termi-
nal with a screwdriver and insert the core from the side. (Refer to
Dimensions
on page 34.) More Sensing Bands can be connected
simply by wiring in an arch shape.
Note:
Check that the wiring is secure before using the K7L in applica-
tions.
Interval Between Stickers
When securing the Sensing Band with Stickers, attach the Stickers at
intervals of 20 to 30 cm in places where the core is not exposed.
Note: 1.
When using the F03-26PE (adhesive-tape model), be sure
to wipe all moisture, oil, and dust from the surface to which
the Sticker is to be attached. Failure to do so may result in
insufficient adhesion, and the Sticker may peel away from
the surface.
2.
When using the F03-26PEN (screw model), before installing
the Sensing Band, it is necessary to perform stud welding.
For details on the pitch of the studs, refer to the information
on the dimensions of Sensing Band Stickers.
