Cautions

Setup Improvement Enhances Productivity
High-Power Automation Pallet Clamp locates and clamps simultaneously.
Fixture changeover becomes faster and easier, and equal clamping force and locating accuracy
are ensured.

When air pressure is cut off
and drops to 0MPa.

MPa

Mechanical locking is built in some steel ball parts.
This enables powerful holding even when air pressure
is at 0MPa. Powerful pulling capacity (holding force)
prevents a pallet fall.
※ Please refer to “Clamping Force Curve” on P. 9 for pulling capacity

PalletFall Prevention(holding force).

Compact Body enables
Smooth Loading

PalletSmooth Loading
The low proﬁle reduces
lifting amount when loading.

Fixture can be smaller with the compact clamp body.
Also, the low clamping and locating part enables
smooth loading/unloading.

Air pressure must be continuously supplied to the air blow port.
PalletAllowable Oﬀset

Allowable Oﬀset

A ﬁxture pallet must be level when loaded or removed
from pallet clamps. The clamps and blocks will bedamaged if the pallet is tilted when loading/unloading(especially when loading). Provide guide pins (rough guide)
to keep the pallet level during loading and unloading.

accuracy on a regular basis, and replace the product in case thelocating accuracy exceeds the allowable range.

may lead to malfunctions and damages.
● Air blow passage should be φ6 or more for an eﬀective air blow.

4) Setting of Seating● In case the clamp/block conﬁguration is linear, it is recommended
to provide additional supports for stability.

3) When Using a Pallet in Vertical Position● When setting a workpiece or a ﬁxture plate, make sure it is inproper proximity and square to the clamps.
If it is locked out of position, the clamps may be damaged.

6) When using with Auto Coupler (JVC/JVD/JVE/JVF).
● WVG does not have a lifting function.
When using with an auto coupler, make sure not to lift or tilt
a pallet, and it becomes the allowable dimension shown on 3).
Locking when the pallet is lifted or tilted, the clamp does notoperate normally, causing damage on the clamp.
Please prepare a tilting prevention.
(Refer to the product catalog on our website for the reaction
force caused by the internal spring of auto coupler.)
7) Clamp Action Conﬁrmation

When using Sensor Attachment (WVGT)● WVGT is equipped with a built-in magnet that detects the clamping
action by using with an auto switch.
● Select an auto switch depending on the environment.
● Please use a magnetic ﬁeld resistant auto switch for anenvironment which generates a magnetic ﬁeld disturbance.
Recommended Auto Switch：D-P3DWA (made by SMC)
● Depending on an installation position of an auto switch, it can beprojected out from the bottom of the sensor attachment.
