Magnetic pistons
are standard so that position sensing switches
can be added at any time without modifying
the cylinder.
Compact yoke
construction allows for reduced piston length
resulting in reduced overall cylinder length.
Unique oval piston design
dramatically reduces overall cylinder height.
Spring-loaded tension arms
located on the work table maintain constant
pressure on the dust seal belt to ensure
external sealing protection.
Oval piston design provides greater load
carrying capacity than typical rodless

Operating Range
(1) M0V5, M0H5, M2V5, M2H5, M3V5, M3H5, M5V5, M5H5: The
operating range is the distance, when the piston moves, between
one position where the switch first turns on and the other position in
the same direction where it turns off. The mid-point in the operating
range is the most sensitive position and the switch should be
mounted at that location.
(2) Proximity switches with two-color indicator, M2WV5, M3WV5:
The operating range is within the red-green-red lights on. The green
light shows the best mounting range.
Hysteresis
Hysteresis is the distance, when the piston moves, between one
position where the switch first turns on and the other position in the
opposite direction where it turns off. Switches should not be located
in this area.

• When connecting and using an inductive load (relays,
solenoid valves), as surge voltage occurs with the switch
off, be sure to wire a protection circuit as shown in Fig. 3.
• When connecting and using a capacitor load, as in-rush
current occurs with the switch on, be sure to wire a
protection circuit as shown in Fig. 4.
• When lead wire is more than 10m long, be sure to wire a
protection circuit as shown in Fig. 5, 6 (for M2, M2WV) or
Fig. 7 (for M3, M3WV).

(1) If more than one M25 and/or M2WV5 switches are wired in series,
the total amount of voltage drop is the sum of all the switches connected.
As voltage at load side is power voltage minus the sum of voltage fall at
switches, check your programmable controller, as being a load, with its
specified input to determine maximum number of connections.
(2) If more than one proximity switch of the 3-wire type are wired in
series, the value of the voltage drop at switches is the total sum of
voltage fall of all the switches connected. As current flowing in the
switches is the sum of the power consumption of all of the switches
connected and load current, as shown below, check the specified load
of switches so that it does not exceed the maximum load current of
switches, and determine the mazimum number of connections.
(3) Lamp is on only when all the switches are on.

On M25 and/or M2WV5 switches, the leakage current increases
based on the number of connections. When one switch turns on
and off, as the voltage at both ends of the switch connected in
parallel drops below the load voltage range down to internal voltage
drop value when switch is turned on, other switches will not turn
on. Therefore, check the specified input of the programmable
controller regarding the connection load before use. M35 and
M3WV5 switches have a small leakage current (under 10µA) so
multiple connections will usually not present a problem or cause
the lamp to fade or stay off.
Avoid using switches near a strong magnetic field or strong current
(large magnet, spot welding machine, etc.). When cylinders with
switches are mounted close to each other in parallel, or when
magnetic material moves near the cylinder, they could cause
interference and affect switch operation.
Avoid using switches near a strong magnetic field or strong current
(large magnet, spot welding machine, etc.). When cylinders with
switches are mounted close to each other in parallel, or when magnetic
material moves near the cylinder, they could cause interference and
affect switch operation.
Minimum bending radius of lead wires should be 3/8". Ensure that
no bending or tension stresses are continuous on the wires. For
moving portion, use wiring similar to that used on robots.
Minimum bending radius of lead wires should be R9 or more. Ensure
that no bending or tension stresses are continuous on the wires. For
moving portion, use wiring similar to that used on robots.
Avoid using a load that exceeds the maximum contact capacity of
the switch. In the case of a lower current than the rated current
value, the M0 switch lamp may not light.
When using an inductive load, such as a relay, etc., be sure to set
the protection circuit as shown in Fig. 1 and Fig. 2. Also, if lead wire
is longer than that specified in Table 1, set protection circuit as
shown in Fig. 3 and Fig. 4.
Connect the lead wire of the switch with load in series type
connection. Do not connect it directly to a power source. In the
case of the M05 switch the following will apply:
(1) When using for DC, connect the black (white) wire to positive,
and blue (black) wire to negative. If the wires are reversed, the
switch will work but the lamp will not light.
(2) When connecting to an AC relay or programmable controller
input, using half wave rectification, the switch may not light. If
this happens, it can be corrected by connecting the switch lead
wires to the opposite polarity.

Use the following relays or equivalents:
Omron, MY or G type Potter & Brumfield KUP type
Furnas 46 type Allen Bradley HC type
If more than one M05 switch is wired in series, value of voltage drop at
switches are the total of all the switches connected. In order to ensure
its operation, use one M05 switch and use M55 for the others and the
voltage drop will be limited to that of one M05 switch (about 2.4V).
The lamps will light only when all the switches are on.
Any number of switches can be used in parallel connections, but in the
case of the M0 switch, the lamp might be dimmer or not on at all.

Adjust the stroke by loosening the stopper bolt nut and turning the
stopper bolt. After adjusting the stroke, tighten the stopper bolt
nut to the torque values shown in Figure 2. When adjusting the 16-
25 mm cylinders, due to the small amount of clearance between
the table and the stroke adjustment plate, adjust the stroke by
moving the complete stroke adjustment unit.
Figure 2. Torque values for tightning stopper bolt
nut and shock absorber nut.
Figure 1. Torque values for tightening stroke

772
Downward kinetic energy:
Edn = 6 · 392+ (28+6) · 0.315 = 22.53 in.-lbs.
772
Effective weight, upward:
We up = 6 + 772 · (28-6) · 0.315 = 11.22 lb.
322
Effective weight, downward:
We dn = 6 + 772 · (28+6) · 0.315 = 11.43 lb.
392
Eup = 14.89 is less than 1/2 times 60.8 (See Figure 4) - OK
Edn = 22.53 is less than 1/2 times 60.8 (See Figure 4) - OK
We up = 11.22 is less than 32 (See Figure 3) - OK
We dn = 11.43 is less than 31 (See Figure 3) - OK
Example 2. Horizontal Mounting
Weight attached to piston table - 6 lb.
Impact velocity - 36 in./sec.
Working Pressure - 50 psi
Actual propelling force - 20 lb.
(see Figure 13, page 26)
Kinetic energy:
E = 6 · 322+ 20 · 0.315 = 16.37
772
We = 6 + 772 · 20 · 0.315 = 11.25
362
E = 16.37 is less than 1/2 times 60.8 (See Figure 4) - OK
We = 11.25 is less than 32 (See Figure 3) - OK
Intermediate Stroke Stop
Slit tube type rodless cylinders, by the nature of their design, will allow
a very small amount of air to leak externally including the SRL2-M
which has non-detectable, minimal leakage. To try to stop and hold a
cylinder in an intermediate position will require a three position valve
with both cylinder ports open to pressure in the circuit for more
satisfactory results. See Figures 5 and 6.
Horizontal Weight
The circuit in Figure 5 shows that equal pressure is applied to both
sides of the piston when it stops which prevents the table from jumping
out of position at restart.
Vertical Weight
As shown in Fig. 6, the table moves in the same direction as the weight
in a vertical application. Install a regulator with a check valve to reduce
the cylinder thrust on the upper side to balance the weight and force on
the lower side.

Piping
Piping should be of a rust resistant material and be of a sufficient
internal area for piston speed required. Make sure that piping is clean
and free from sealing compound before connecting to system.
End Port Piping
Refer to Figure 7 to determine when end port piping can be used with
various types of mountings relative to fitting clearance.

On all bore sizes with axial foot mounting (LB or LB1), the end port
pipe fittings will obstruct the mounting holes. To avoid this problem,
mount the cylinder first and tighten the mounting bolts and then attach
the pipe fittings to the cylinder ports.
Cushion Adjustment
Cushion adjustment screws are located next to the ports on the side of
the cylinder. The cushion effect can be reduced by loosening the
cushion screw (turning counterclockwise). If the cylinder is subjected
to high kinetic energy due to a heavy load or high speed, etc., an
external cushion device should be considered to absorb the kinetic
energy load. See stroke adjustment and shock absorption option.
Quality of Compressed Air
Use clean, dry compressed air to operate the cylinder. This can be
accomplished by installing a filter with a proper filtration rating and
flow rate ahead of the directional control valve and draining the filter
regularly to ensure that no moisture or contaminants are allowed into
the system.
Work Environment
System components should be mounted in areas free from corrosive
atmosphere, rain, water and direct sunlight. If cutting oils, coolants, oil
mists, etc. are present, the cylinder should be covered or protected to
avoid damage to the seals. Also, avoid areas where cutting chips, dust,
spatter, etc. will come in contact with the cylinder.
Under normal usage, the cylinder has an effective dust-seal belt which
prevents contamination from entering the interior of the cylinder.
However, under unusually dusty or contaminated operating conditions,
it is recommended that the cylinder be mounted with the work table and
dust-seal belt facing down. When mounted in this fashion, be sure to
check the weight deflection chart to ensure that the unsupported tube is
not overloaded. C-mounts are available for use in these circumstances.
See pages 14 and 15 for C-mount dimensions.
External Guides
When external guides are employed, ensure that excessive forces are
not transmitted to the cylinder due to friction, misalignment, or
deflection of the external guides. Use of a floating joint is
recommended. See pages 28-31 for application forms and pages 14
and 15 for floating joint dimensions.
Other Considerations
Avoid electric welding around the rodless cylinder as current could be
conducted through the cylinder tube and destroy the dust belt.
Excessive inertia will cause the cylinder to malfunction. Ensure that
inertia loads are within allowable range.
Deep scratches or dents on the cylinder tube from external means may
have an effect on cylinder performance.
If negative pressure (vacuum) is caused in the cylinder by excessive
external force or inertia force, the pressure seal belt may be drawn
away from the slit tube causing external leakage. Ensure that no
negative pressure or vacuum can be generated inside the cylinder.
