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>
Mount the reflective mirror horizontally or vertically toward LS-H□-A.
<Fig. 2 Improper positioning>
The reflective mirror must not be tilt toward the LS-H□-A.

COAXIAL RETROREFLECTIVE TYPE
(Only for LS-H91-A)
● In principle, the coaxial retroreflective type (LS-H91-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 applica-
ble amplifier LS-400 series, sufficient margin should be taken into
account.

SPOT-SIZE ADJUSTER (Only for LS-H21-A)
● The diffuse reflective type (LS-H21-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.
<Connector for amplifier connection>
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
operating lever (white) through the
releasing slot, and lift the screw-
driver 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.
