When cylinder is installed.
When fixing cylinder bolts to fix this cylinder, use stainless
steel bolts to maintain the characteristics of the sensor.
If an iron bolt is used, distortion may occur in the sensor
output voltage waveform, display error could increase, and
analog output voltage linearity could drop.
(Repeatability is not affected, but performance should be
confirmed before operation.)
Similar problems may occur if the cylinder contacts a mag-
netic object, especially near the LN Sensor or when the
steel plate is shorter than the actuator.
The length measuring sensor and analog output voltage
ON-OFF select T0H/V (Note) or LN-TH/V switch or other
cylinder switches can be mounted on the same surface if
the mounting positions do not interfere.
Always connect a cylinder switch (T0H/V or LN-TH/V) to
retrieve the analog output voltage within a random 8mm
interval (10mm for display type) of the cylinder's full stroke.
Tighten the sensor with a torque of 0.1 to 0.2 N·m, and
install so that sensor set screw faces the cylinder head.
(Note) The selected switch differs with the type of cylinder,
analog output, and the display.
When hand is installed
If a magnetic substance such as steel plate is used for the
base when installing the hand on the top using the socket
and spigot, the analog output voltage linearity may drop.
(Repeatability is not affected, but performance should be
confirmed before operation.)
Similar problems may occur on the front or side of the hand
if the section contacts a magnetic object.
When fixing the hand on the top, side or front, use stainless
steel bolts to maintain sensor characteristics.
Tighten the sensor with a torque of 0.1 to 0.2 N·m, and
install so that the sensor set screw faces the master key
(jaw).

Precautions for cylinder and hand
With the display, if a load short-circuit current flows to the
switch output stage transistor because of incorrect wiring or
connections, etc., the internal short-circuit protection circuit
will cut the short-circuit current. (The output indicator (yel-
low) turns off and the short-circuit indicator (red) turns on.)
To reset short-circuit protection, turn off supplied current once,
correct wiring mistakes, etc., then turn the current on again.
This product’s protective circuit is effective only against spe-
cific incorrect connections and load short circuits. It does not
necessarily provide protection against all incorrect connections.
To prevent dislocation after fitting the connector's male and
female sides, fix the female side to the male side with screws
on the female side.
2. Analog output indicator type
If the operating range is too narrow or if the operat-
ing points are incorrectly adjusted when setting the
switch output operating position, the output may or
may not turn ON. Readjust in this case.
The operation is stabilized by turning the operating
range adjustment trimmer clockwise and widening
the operating range slightly.
If a load short circuit current flows to the output stage
transistor because of incorrect wiring or connections,
etc., the internal short circuit protection circuit func-
tion (indicator light change from ON to OFF), and
the short circuit current be cut.
To cancel the short circuit protection, turn the power
supply OFF once, correct any incorrect wiring or con-
nections, and then turn power ON again.
This product’s protective circuit is effective only
against specific incorrect connections and load short
circuits. It does not necessarily provide protection
against all incorrect connections.
Install the sensor at a position where the red lines
on the hand and sensor are aligned. Tighten the sen-
sor with a torque of 0.1 to 0.2 N·m, and install so the
sensor set screw faces the master key (jaw).
