Thank you for purchasing a Citizen absolute contact-type displacement sensor.
Read this instruction manual before use and use this unit properly.
After reading this instruction manual, keep it where the user can find it easily.
Also make sure the prescribed performance is ensured before use.

Mount the sensor at right angles to the surface subject to measurement.
Mounting it at another angle may cause measurement errors. It may alsosignificantly shorten the service life.

! NOTICE*1

Absolute Contact-type Displacement Sensor
SA-S□10，SA-S□10/03N

Mount the sensor with the measuring probe pointing at 3 to 9 o’clock. If you wish touse it in another posture, please contact our Sales Department.

This is the rubber bellows for replacement. It is equipped as standard.
(It is not equipped with SA-S 10/03N.)*2
This is the replacement measuring probe. It is equipped as standard.
Measuring probes other than the standard ceramic probes are available.
Please contact the dealer you purchased this product or our Sales Department.

10) The mechanical response speed of this product is the value obtained when thespindle is moved at a constant speed with no shock, while the measuring probe ispointing straight downward.
If the spindle is subjected to excessive shock, errors may occur or the spindle
may be damaged.

8. Maintenance<Replacement method of the measuring probe>
As shown in the figure below, replace the measuring probe while engaging thespanner provided as an accessory across the flats of the spindle that are for thispurpose.
Do not remove the measuring probe with the main unit secured.
If the measuring probe is replaced while securing the body of the product,
the rotational force is transmitted through the spindle to the inside of theproduct, and the photoelectric converter attached to the spindle may
malfunction and cause damage to the sensor.

11) The rubber bellows are a functional part for dust and water proofing. Do notremove them.
12) Take care not to damage the rubber bellows, such as by cutting.
Also, replace the rubber bellows with new ones before damage occurs.
Replace the rubber bellows in accordance with the replacement proceduredescribed in this instruction manual “8. Maintenance”.
Improper replacement may deteriorate the dust and water resistance.
13) Take adequate measures to prevent damage (safety measures) should this productfail.

5. Dimensions and Part Names

1. General
This product is a high-accuracy contact-type displacement sensor that detects theabsolute position of the spindle optically and outputs it with high resolution.
In combination with the separately-sold SA Series controllers, this product serves as alength-measuring system.
Note that this product is not compatible with conventional IPD Series counters.
In contrast to the existing IPD Series that count pulses, it does not skip values.
Another feature is that it does not forget the position when the power is switched off, so
there is no need to calibrate it with a master when the power is switched on.
It is also equipped with a 3-color status indicator lamp that makes it possible torecognize pass/fail judgment results and errors at a glance.
As for the structure, two bearings are arranged at top and bottom, giving highresistance to vibration and shock in a slim form.

Accessory spanner! NOTICE(1)14) Secure the connection cable properly so that excessive force will not be applied tothe sensor when in use.
If force is applied through the connection cable to the sensor, the accuracy
may deteriorate, or the sensor may be damaged.
15) Avoid wiring the cable in parallel with high voltage cables or power lines. This may
cause a malfunction.

7. Mounting Method (Recommended)

When nut-mounted

When mounting a standard-type sensor on a unit or in a holder, hold it either with the nut
provided as an accessory, or use a split bushing.

When mounted with a straight connector

When mounted with an angle connector

1) Holding method using the nut
The plate thickness for mounting with the nut is 6.5 to 12.5 mm.
Be sure to tighten the nut with the tool provided as an accessory engaged on thehexagonal section at the base of the spindle. The tightening torque shall be lessthan 12.5 N⋅⋅m.
After fully tightening the nut, make sure that the spindle moves smoothly.

6. Precautions for Use<Replacement method of the rubber bellows>
1) Removal
Remove the measuring probe in accordance with the above procedure.
Detach the rubber bellows at groove A located at the stem side first and then at
groove B located at the measuring probe side.
2) Installation
Before installing the rubber bellows, wipe the spindle with anhydrous alcohol.
Insert the rubber bellows to the middle of the stem and measuring probe (Seethe figure below).
Attach the rubber bellows to groove A located at the stem side first and then togroove B located at the measuring probe.
When attaching the rubber bellows, take care not to smear the spindle. Failure
to do so may cause a malfunction.
If the spindle happens to become soiled, wipe it clean with absolute alcohol.
After the installation, check the parting line (a line generated on a mold partingsurface) for twisting.
Twisted parting lines may interfere with the performance.
After installing the rubber bellows, install the measuring probe by following theprocedure.

Stem side A

When connecting the connector, engage it firmly and tighten the threaded part securely.
(Recommended tightening torque: 0.2 to 0.3 N⋅⋅m)
If it is tightened too weakly the protective structure will not be maintained, or it may
loosen due to vibration.

Measuring probe side B

Accessory spanner
Accessory nut2) Holding method using the split bushing
When installing with a split bushing or CITIZEN indicator bushing (M-150), tighten
an M6 screw with a torque of 0.5 N·m or less.
Be sure to clamp the holding part. At this time, avoid using the screw to directly
clamp the holding part.

Do not expose this unit to impact due to dropping etc. or excessive force. Doing somay cause damage or errors.
Do not attempt to disassemble or reconstruct this unit.
Do not use this unit under rapid temperature changes or condensation.
Perform the following checks and inspections before use:
Make sure that the spindle moves smoothly.
Make sure that the measuring probe is not loose.
Make sure that a displayed value remains stable at the datum point using a
block gage.
Do not use this unit in the presence of an excessive magnetic field or electricalnoise is present. Doing so may cause a malfunction or failure.
Avoid applying excessive lateral force. It may cause deterioration in measuring
accuracy and durability.
There may be variation in measured values at the stroke end, so do not take thestroke end as the datum.
Take a position where the probe is pushed in at least 0.1 mm from the stroke end
as the datum.
