MOUNTING
● The tightening torque should be 0.5N･m
or less.
● When placing the sensor horizontally or vertically, the reflector must also be
positioned horizontally or vertically as shown in Fig. 1 below. If the sensor is
placed horizontally or vertically but the mirror is tilted as shown in Fig. 2 below,
the reflection amount will decrease, which may cause unstable detection.
<Fig. 1 Proper positioning>
When placing the sensor horizontally or vertically, the reflector shall also be
positioned horizontally or vertically.
<Fig. 2 Improper positioning>
When placing the reflector tilted even when the sensor is positioned horizontally
or vertically.

COAXIAL RETROREFLECTIVE TYPE
(Only for LS-H91F-A)
● In principle, the coaxial retroreflective type (LS-H91F-A) may be unable to
detect a mirror object or an object which easily diffuses the receiving light at a
short sensing distance since the polarized light becomes unstable.
In this case, take the following measures.
<Measures>
Lower the sensitivity of M.G.S. function of the amplifier.
・
Change the response time.
・
Make the distance between the sensor head and the sensing object farther.
・
● The receiving light intensity may change depending on the surface condition
of the reflector. When a threshold value is set with the applicable amplifier
LS-400 series, sufficient margin should be taken into accout.

SPOT-SIZE ADJUSTER (Only for LS-H21F-A)
● The diffuse reflective type (LS-H21F-A) incorporates the spot-size adjuster to
adjust the size of spot diameter.
Spot-size adjuster
Turn the spot-size adjuster clockwise or counterclockwise to adjust the
spot diameter at your desired detecting distance.
However, if the adjuster is over turned, it may be damaged.

WIRE CONNECTION
● The cable of sensor head can be shortened to your desired length. However,
it cannot be extended.

Wire inlet
Releasing procedure
① Use a flat-head screwdriver (Blade width: 2mm or less) to push
the operating lever (white) located at the wire inlet and remove
the wire.
Blade width
2mm or less
Wire connecting procedure
① Process the core length to 7 to 8 mm in accordance with 'STRIP GAUGE'
indicated on the side of this unit, and twist the core several times.
When using shielded wires,
twist the wire until obtaining the
diameter of φ1.2 mm or less.
② Use a flathead screwdriver (Blade
width: 2 mm or less) to push the
operating lever (white) located at the
operating area until it is locked.
③ Insert the wire to the innermost of
the wire inlet.
Check that the shielded wire is
properly inserted into the wire inlet
as well as that the core end has
passed through the wire connection
area as shown in the right figure.

④ Place the head of a flathead screw-
driver underneath the operating
lever (white) through the releasing
slot, and lift the screwdriver head
If you hear a snap, the operating
lever (white) is returned and the wire
is fixed.
⑤ Lightly pull the wire to ensure that
wire is not loose. When using
shielded wires, also check that they
do not contact each other.
