This product is class A equipment that is intended for use in an industrial
environment.
There may be potential difficulties in ensuring electromagnetic
compatibility in other environments due to conducted as well as radiated
disturbances.
■Handling Precautions
○Follow the instructions given below for selection and handling.
Product Handling
•This product is a tool to simply measure the speed of a pneumatic
cylinder, the cycle time and number of operations per minute. The
accuracy of the measurement is not guaranteed.
•It is the responsibility of the user to verify the product alone and as
part of a system and to determine the applicability of the product.
•Handle with care.
Warning
•This product uses AA batteries (1.5 V) only. Do not use any other
voltage as this may cause failure.
•Before mounting the sensor to the cylinder, stop the operation of the
device to avoid injury.
•Do not use the product if there is smoke or a strange smell.
•Do not handle with wet hands. Avoid getting the product wet.
•In case of a malfunction, stop using immediately.
•This product is a piece of precision equipment. Do not disassemble
or modify the product.
Precautions
•Do not insert wires or metal objects into any holes or gaps. This
may cause electric shock, failure or fire due to short-circuit.
•SMC will not be held responsible for any equipment problem or
failure due to the measurement results of this product.
•Avoid repeatedly bending or stretching the lead wire. This may
break the wire.

■Installation
The Measurement value is indicated with a minus (-) to distinguish
between the extension and retraction of the cylinder.
Mounting as the figure below:
∗
Extension (Stroke direction): Positive direction
Retraction (Reverse stroke direction): Reverse direction is signified with
a (-) value
If the sensor are installed
incorrectly the speed will not
be measured (as above).

Speed measurement
•This product uses the magnetic field of the pneumatic cylinder piston
(with built-in magnet) to measure the time taken for the piston to pass
two magnetic sensors, and converts the time into the speed of the
cylinder.
•The speed that is displayed is the speed close to the sensor. This is
the average speed between two sensors (approx. 3.7 mm). The speed
during acceleration is the average speed.
Cycle time and count measurement
•For measurement of cycle time or count, the supplied sensor cannot be
used. An auto switch must be purchased separately.
•A 3-wire NPN type auto switch is suitable for the measurement of cycle
time or count.
The speed results may vary depending on the conditions below.
•Individual variation between cylinders with built-in magnet.
•Magnetic characteristics due to cylinder bore size.
•Variation due to the magnetic field around the cylinder.
•Individual variation between sensors.
•Variation due to temperature change.
∗
1: AA alkaline battery is not included. Prepared by the user.
∗
2: For speed measurement mode, use the sensors supplied.
(Do not use any other sensor.)
∗
3: For cycle time measurement mode, supplied sensor cannot be used (auto switch is
not included and must be purchased).
Auto switch (SMC 3-wire NPN auto switch) and connectors are purchased
separately.
∗
4: Battery life depends on the operating environment.
■Installing the batteries
(1) Slide the lid at the rear of the unit. Insert the batteries.
Applicable battery is "AA battery (1.5 V)"
Batteries are not included. Prepared by the user.
Make sure the polarity is correct when inserting the batteries.
(2) Close the lid after inserting the batteries.
(3) When the product is used and the battery has expired,
the low residual battery error will be displayed.
Replace the batteries.
■Wiring
•Connection of M8/M12 connector
(1) Tighten by rotating the knurled part of the connector body. Connection
is complete when the knurled part is fully tightened.
(2) Check that the connection is not loose.
•Assembilng the Auto switch and connector
Refer to "Assembly Procedure" attached to the connector for wiring of
PCA-1557730 (connector for M8) or PCA-1557743 (connector for M12).
Connect the lead wire colours as specified by the connector.

mode".
All segments
ON
Changes to the previous
measurement mode.
■Power OFF (Auto Power Off function)
The power turns OFF when the
button is held for 3 seconds or longer.
If no buttons are pressed for 15 minutes, the power will turn OFF
automatically. (Auto Power Off function)

When the power is ON and the back light is OFF, the back light is turned
ON by pressing the
button for 5 seconds or longer.
When the power is ON and the back light is ON, the back light is turned
OFF by pressing the
button for 5 seconds or longer.
∗
: Although it is possible to measure when the sensor is mounted in reversed
direction, the displayed direction will be reversed.
○Switch setting
(1) Fully extend the rod, and slide the sensor towards the rod end.
(2) Stop the sensor when the green LED
turns ON, and fix the sensor with the
mounting screw.
Tightening torque is 0.1 to 0.2 Nm.
∗
: When the sensor is installed, the
speed from Rod to Head may not be
displayed depending on the type of
cylinder.
