■ Precautions for Handling
Follow the instructions given below for selecting and handling of the vacuum gripper unit.
Product specifications
- It is recommended to use compressed air which purity class is 2:6:3 of ISO8573-1:2010.
- The applicable fluid is air.
Do not use a fluid containing chemicals, synthetic oils including organic solvent, salt and corrosive gases.
Otherwise, damage to the vacuum gripper unit and malfunction can result.
- Use the specified operating pressure.
- Reserve a space for maintenance.
Design the system allowing the required space for maintenance.
- Use the specified voltage. Otherwise failure or malfunction can result.
-Do not exceed the specified maximum allowable load. Otherwise it can cause damage or shorten the life of the product.
- Design the product to prevent reverse current when the circuit is opened or the product is forced to operate for
operational check. Reverse current can cause malfunction or damage the product.
Operating environment
- Do not use in an environment where corrosive gases, chemicals, sea water, water or steam are present.
- Do not use the product in a place where the product could be splashed by oil or chemicals.
If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent, even for a
short time, the solenoid valve or pressure switch may be adversely affected (damage, malfunction, or hardening of the
cable and lead wires).
- Do not use in an area where surges are generated.
When there are machines or equipment that generate large surge near the pressure switch (magnetic type lifter, high
frequency inductive furnace, motor, etc.), this can result in deterioration and damage of the internal elements. Take
measures against the surge sources, and prevent the lines from coming into close contact.
- Do not use a load which generates surge voltage.
When a surge-generating load such as a relay or solenoid is directly driven, use the product with a surge absorbing
element built-in.
- Mount the product in a location that is not affected by vibration or impact.
It will cause failure or malfunction.
- Do not use the product in an environment that is exposed to temperature cycle.
Heat cycles other than ordinary changes in temperature can adversely affect the inside of the product.
- Do not expose the product to direct sunlight.
If using in a location directly exposed to sunlight, protect the product from the sunlight.
- Keep within the specified operating fluid and ambient temperature range.
Operation under low temperature may lead to damage or operation failure due to frozen moisture in the fluid or air.
Protection against freezing is necessary. Mounting of an air dryer is recommended for elimination of drainage and water.
Avoid abrupt temperature changes even within the specified temperature range.
- Do not use in a location where the product is exposed to radiant heat from surrounding heat sources.
Insufficient air quality may cause operation failure.

Refer to “3.4. How to order”
Note 1) The weight changes by the selected suction cup. Refer to “3.4 How to order”.
Note 2) Limited by the cup diameter, mounting orientation or workpiece. The weight of the workpiece shall be maximum
workload or less.
Gripping or transfer of workload exceeding the maximum workload leads to the decrease of vacuum due to air leakage.
Note 3) Impact resistance: The characteristics are satisfied after tested one time in each of the X, Y and Z directions without
energization. (Initial value)
Vibration resistance: The characteristics are satisfied after tested a one sweep in each of the X, Y and Z directions at 10
to 500 Hz without energization. (Initial value)
Note 4) Values at the standard supply pressure. Values are based on standard of SMC measurements. They depend on
atmospheric pressure (weather, altitude, etc.) and measurement method.
Note 5) This shows the pressure just before the supply (P) port.
The performance such as vacuum pressure may reduce, depending on supply air capacity, the piping volume (piping
length and diameter) and affection of air consumption of other devices which operate at the same time.

3.2. Flow rate / Exhaust characteristics
■Flow rate / Exhaust characteristics.
The flow rate characteristics correspond to the standard supply pressure (0.5MPa).
* The actual suction flow at the point of suction varies depending on the piping conditions to the vacuum port.
■How to read the flow rate characteristics Graph
Flow rate characteristics are expressed in ejector vacuum pressure and suction flow. If suction flow changes,
the vacuum pressure will also be changed. Normally this relationship is expressed in ejector standard
operating pressure use. In the graph, Pmax is maximum vacuum pressure and Qmax is maximum suction
flow. The values are specified according to catalog use. Changes in vacuum pressure are expressed in the
below order.
1. When the ejector suction port is covered and made airtight, the suction flow becomes zero and vacuum
pressure is at the maximum value (Pmax).
2. When the suction port is opened gradually, air can flow through, (air leakage), suction flow increases, but
vacuum pressure decreases. (condition P1 and Q1)
3. When the suction port is opened further and fully opened, suction flow moves to the maximum value
(Qmax), but vacuum pressure is near zero (atmospheric pressure).
As described above, the vacuum pressure changes when the suction flow changes. In other words, when
there is no leakage from the vacuum port, the vacuum pressure can reach its maximum, but as the
amount of leakage increases, the vacuum pressure decreases. When the amount of leakage and the
maximum suction flow become equal, the vacuum pressure becomes almost zero.
In the case when a ventilative or leaky workpiece should be gripped, take note that vacuum pressure will
not rise.

3.3. How to calculate theoretical lifting force
This manual shows how to calculate theoretical lifting force only. Refer to the catalog of suction cups forfurther
detail of suction cup selection method.
■How to calculate theoretical lifting force
The theoretical lifting force of a cup can be found by calculation or from the theoretical lifting force table.
Calculation
Theoretical lifting force table
The theoretical lifting force (not including the safety factor) can be determined by the cup diameter and vacuum
pressure.
The required lifting force can then be determined by dividing the theoretical lifting force by the safety factor t.
Lifting force = Theoretical lifting force / t
Theoretical lifting force (Theoretical lifting force = P x S x 0.1)

4. Mounting
Perform the mounting of the vacuum gripper unit and accessories by following bellow.
①Connector storage
Set the three connectors at the end of the robot arm according to the characters printed on the flange.
The connection part of the connectors are set in the direction of the arrows.
②Mounting the connector storage flange
Mounting a parallel pin to the end of the robot arm, and mount the connector storage flange with the
attached hexagon socket head cap screw. (Tightening torque: 3.0 ± 0.3 N・m)

③Mounting the vacuum gripper unit
Before mounting the product, adjust the position of the robot arm so that it is easy to mount the
product.
1) Mount parallel pin (6x10) to connector storage flange mounted in ②, and mount robot mounting
flange with the attached hexagon socket head cap screw(M6x10).
(Tightening torque：5.2±0.5N・m)
2) Mount vacuum gripper unit to robot mounting flange with hexagon socket head cap screw(M6x10)
so that the protrusion of robot mounting flange and the notch of vacuum gripper unit match.

⑤Mounting of piping joints and coil tubes
1) Remove secondary piping plug (No.1 to No.4) in one place and mount the attached
One-touch fitting (KQ2L04-M3G1).
2) Mount the attached plug-in reducer (KQ2R06-04A1) to One-touch fitting (KQ2L04-M3G1),
and piping the coil tube (TCU0604B-1) to both plug-in reducer and vacuum gripper unit.
3) Remove truss screw (M4,4 places) on the base of the robot body and slowly remove the
base cover.
Depending on the posture of the robot body, it may be difficult to remove the base cover.
Change the posture of the robot in advance by jog to make it easier to work.
4) Take out the Φ4 tube (No.1 to No.4) and Φ6 tube (white) from the opening.
5) Connect the Φ4 tube tubing No. should be the same as the airport No. to which the
one-touch fitting is connected in step 1 above and white Φ6 tubing with a one-touch fitting.
