2.Operating method or operation
2-1. Design precautions
Warning
1. The product is designed for use only in compressed air systems. Do not operate at pressures or
temperatures, etc., beyond the range of specifications, as this can cause damage or
malfunction. (Refer to the specifications.)
Please contact SMC if using for fluids other than compressed air. We do not guarantee against
any damage if the product is used outside of the specification.
2. Take safety measures (e.g. mounting protective covers) when workpieces pose a danger of
fingers being caught in a gripper, etc.
3. There is a danger of workpieces dropping if there is a decrease in gripping force due to a drop in
circuit pressure caused by a power failure, etc. It is necessary to take measures such as drop
prevention so that injury and damage to machinery or equipment can be prevented.
2-2. Selection
Warning
1. The gripping point should be set within the limited range.
When the gripping point distance becomes large, the gripper attachment applies an excessively
large load to the gripper sliding section, and causes adverse affects on the life of the gripper.
Refer to the catalog for details.
2.When using single acting type, use it within the allowable moment.
When a moment as shown in the figure below acts on a finger, the spring force may not allow the finger
to return to its original position, so use within the moment shown in the table below.

3. Attachments should be designed to be as light and short as possible.
(1) A long or heavy attachment increases the inertia force required to open or close the fingers.
This may cause unsteady movement of fingers and have an adverse affect on the life of the
gripper.
(2) Design the attachment as short and light as possible even if the gripping point is within the
limited range. Refer to the catalog for details.
(3) Select a larger size gripper or used two or more grippers for handling a long and/or large
workpiece.
4. Provide a run off space in the attachment when using with a small or thin workpiece.
If a run off space is not provided within the finger part, gripping becomes unsteady, and it may
lead to gripping failure or slippage.
5. Select a model whose gripping force is compatible with the workpiece mass.
Incorrect selection may lead to the dropping of a workpiece, etc. Refer to the model selection
criteria of each series for the effective gripping force and the workpiece mass.
6. Do not use the product in applications where excessive external force or impact force is applied.
It may cause product failure. Please consult with SMC if necessary.
7. Select a model having a sufficient working finger opening/closing width.
< In case of insufficient width >
(1) Gripping becomes unsteady due to variations in opening/closing width or workpiece
diameter.
(2) When using an auto switch, the detection may not be reliable. Refer to the Auto Switch
Hysteresis section and set the stroke including the hysteresis length for a reliable switch
function. When using the water resistant 2-color indicator auto switch, the gripper stroke may
be limited by the setting of the indicator color during detection.
8. Please consult with SMC regarding a single acting, spring force only grip type.
In some cases, this can cause unstable gripping or return malfunction, due to faulty operation,
etc.
9. Do not disassemble or modify (including additional work) the product in any manner other than that
described in this manual.
Failure to do so may result in injury or accident.
10. When using with auto switch incorporated, please refer to Auto Switch/Common Precautions in the
catalog.

3. Adjust the gripping point so that an excessive force will not be applied to the fingers when
inserting a workpiece.
Confirm that the gripper can operate without receiving any shock by testing it in manual
operation mode or by low speed operation.
4. Control the opening/closing speed with the speed controller to avoid excessive high speed
operation.
If the finger opening/closing speed is greater than necessary, impact forces on the fingers
and other parts will increase. This can cause a loss of repeatability when gripping a
workpiece and have an adverse effect on the life of the gripper unit. It may be
difficult to adjust the speed using meter-out control depending on the piping condition. In
this case, adjust the speed using meter-in control or with dual speed controllers.
5. Auto Switch Fixing Method
To fix the auto switch, insert it into the auto switch mounting groove of the air chuck from the direction
shown in the figure below, set the mounting position, and tighten the supplied auto switch mounting
screw using a flat-blade watch driver.
Note) When tightening the auto switch mounting screws, use a watch driver with a grip diameter of
about 5 to 6 mm.
The tightening torque should be about 0.05 to 0.15 N-m.
