The amount of rod movement in the stroke reading cylinder is
detected using an MR element (magnetic resistance element)
whose resistance value changes due to magnetic force. The
detection unit containing this MR element is called the sensor
head. An amplifying circuit and a dividing circuit are required to
produce output which can be read by the counter, and these are
attached to the cylinder case. The sensor head and amplifier
section together are referred to as the sensor unit.
The stroke reading cylinder is equipped with the capability of
outputting the piston stroke movement as a pulse signal. The
measurement principle is as shown in the drawing below.
1. Scales of magnetic layers and non-magnetic layers are etched
at a certain pitch on the piston rod.
2. With movement of the piston rod, a sin, cos 2-phase signal
(Signal (1)) is received by the magnetic resistance element. For
this wave form, 1 pitch (0.8 mm) becomes exactly 1 cycle.
3. This is amplified and divided into 1/8 parts. As a result, a 90°
phase difference pulse signal of 0.1 mm/pulse (Signal (2)) is
output.
4. By measuring this pulse signal with the counter, it is possible to
detect the piston position with a resolution of 0.1 mm.
5. In the case of the high precision stroke reading cylinder, the sin,
cos 2-phase signal obtained in 2 is amplified and divided into
1/20 parts. As a result, a 90°phase difference pulse signal of
0.04 mm/pulse (Signal (2)) is output.
6. By multiplying this pulse signal by 4 with the counter, it is
possible to detect the piston position with a resolution of 0.01
mm.

When movement is expressed by a single line of pulses, it is
impossible to accurately identify the current position, because
pulse waves appear in both upward and downward directions.
Accordingly, in A/B phase difference output, two lines of pulses are
provided, wherein one line detects the movement and the other
distinguishes the direction.
The CE1 also employs this system.
This function increases resolution 4 times by counting 4 for each
cycle of pulses, instead of counting 1 for each cycle as is normally
the case. In principle, this function counts each time there is a rise
or fall in either of the A or B phase pulses.
Counting speed indicates the number of pulses that can be
counted per second. If the stroke reading cylinder is operated at
high speeds, pulse waves are output in shorter cycles. The
counting speed of the counter must be higher than the pulse speed
for the maximum piston speed when operating. Since the stroke
reading cylinder outputs one pulse for each 0.1 mm of movement,
5,000 pulses will be output for each 500 mm of movement.
Therefore, a speed of 500 mm/s is equivalent to 5 kcps (kHz), but
a counting speed 2 to 3 times greater is recommended for actual
operation.
The accuracy is the difference between the dimensions based
upon the signals of the stroke reading cylinder and the absolute
dimensions.
The maximum display error that will appear on the counter’s digital
display is equal to twice (±1 count) the resolution when the home
position is reset and when dimensions are measured.

1. When screwing a nut or fitting, etc. onto the threaded section at
the end of the piston rod, return the piston rod to its fully
retracted position, and grasp the exposed portion of the rod
across two parallel sides with a wrench. In the case of the high
precision stroke reading cylinder, there are no parallel sides.
Secure the workpiece with a double nut.
Note) Do not apply rotational torque to the piston rod.
2. Operate the cylinder in such a way that the load is always
applied in the axial direction.
• In case the load is applied in a direction other than the axial
direction of the cylinder, provide a guide to constrain the load
itself.
• When mounting a cylinder, centering should be done carefully.
3. Avoid using the air cylinder in such a way that rotational torque
would be applied to the piston rod.
4. Be careful to avoid scratches or dents, etc. on the sliding
sections of the piston rod.
1.
The sensor unit is adjusted to an appropriate position at the time of
shipment. Therefore, never detach the sensor unit from the body.
2. The sensor cable should not be pulled with a strong force.
3. Since the sensor for stroke reading cylinder adopts the magnetic
method, it may result in malfunction if there is a strong magnetic
field around the sensor. Use it under the external magnetic field
with 14.5 mT or less.
This is equivalent to a magnetic field of approximately 18 cm in radius from a
welding area using a welding amperage of almost 15,000 amperes. To use
the system in a magnetic field that exceeds this value, use a magnetic
material to shield the sensor unit.
4. Switches or relays, etc. should not be installed in the power
supply line (12 to 24 VDC).
∗When using SMC extension cable and counter.
Stroke reading cylinder
Multi counter CEU5
When the stroke reading cylinder is used near a motor, welding
machine or other source of noise generation, there is a possibility of
miscounting. In this case, noise should be suppressed as much as
possible and the following countermeasure should be taken.
1. Connect the shield wire to FG (flame ground).
2. The maximum transmission distance for the stroke reading
cylinder is 23 m, but since the output signal is a pulse output, the
sensor cable should be wired separately from other power lines.
1. Connect only the shield wire to FG (frame ground).
2. Use a power source separate from large motors and AC valves,
etc.
3. Run the stroke reading cylinder’s cable away from other power
lines.
4. Install a noise filter in the 100 VAC power line, a varistor in the
DC power supply of the sensor cable and a ferritic core in the
signal line (sensor cable).
Methods of dealing with noise are given below.
Earth ground

Red
Black F.G.

Varistor: ERZV10D220
(Made by Panasonic Corporation)
Noise filter: RSEL-2003W, etc.
(Made by TDK-Lambda Corporation)
Ferritic core: GRFC-10, etc.
(Manufactured by KITAGAWA
INDUSTRIES CO., LTD.)
If sources of noise generation
(motors, AC type valves,
relays, etc.) are connected on
the secondary side of the
noise filter, the filter will have
no effect.
<Counting speed of counter>
When the speed of the stroke reading cylinder is greater than the
counting speed of the counter, the counter will miscount.
For CE1 (when measuring to 0.1 mm), a counter should be used
with a counting speed of 10 kHz (kcps) or more.
And for CEP1 (when measuring to 0.01 mm), use a counter with a
counting speed of 50 kHz (kcps) or more when 4 times
multiplication is input.
<Malfunction due to lurching and bounding>
When lurching or bounding occurs at the beginning or end of stroke
reading cylinder, or due to other causes, the cylinder speed
momentarily increases, and there is a possibility of exceeding the
counting speed of the counter or the response speed of the sensor,
thereby causing a miscount.
The operation manuals should be read before using the CEP1 series
high precision stroke reading cylinder, CEU5 multi counter, CE1
scale cylinder and CEU1 3 point preset counter.

Input/Output
The input/output of the stroke reading cylinder is performed by a ø7 shielded
twisted pair wire from the sensor section plus a connector.
Output type
The output signal of the stroke reading cylinder is A/B phase difference
output (open collector output) as shown in the figure below.
The relation between the movement distance and the signal output of the
stroke reading cylinder is that for each 0.1 mm of movement a one pulse
signal is output to both output terminals A and B.
Furthermore, the maximum response speed of the sensor for the stroke
reading cylinder is at a maximum cylinder speed of 1500 mm/s (15 kcps).
