Model selection criteria with respect to

• Although differences will exist depending on the
coefficient of friction between attachments and
workpieces, select a model which will provide a
gripping force as shown in the table below.
Note 1)Refer to the model selection illustration
regarding multiples of the workpiece weight.

5 to 10 times or more

• If high acceleration, deceleration or impact forces
are encountered during motion, a further margin of
safety should be considered.
Example) When it is desired to set the gripping force
at 20 times or more above the workpiece weight.
Required gripping force

Gripping point L (mm)
• Selecting the MHS2-32D.
A gripping force of 92 N is obtained
from the intersection point of the
gripping point distance L = 20 mm
and a pressure of 0.4 MPa.
•The gripping force is 23 times
greater than the workpiece mass,
and therefore satisfies a gripping
force setting value of 20 times or
more.
Operating pressure: 0.4 MPa
Note) For Step 2 , refer to the gripping point for the effective gripping force of each model.

When gripping a workpiece as in the
figure to the left, and with the following
definitions,
n: Number of fingers
F: Gripping force (N)
µ: Coefficient of friction between
attachments and workpiece
m: Workpiece mass (kg)
g: Gravitational acceleration (= 9.8 m/s2)
mg: Workpiece weight (N)
the conditions under which the
workpiece will not drop are
n x µF > mg

which is at least 10 to 20 times the workpiece weight.
• If high acceleration, deceleration or impact forces are encountered during motion, a further margin of safety should be considered.

Gripping Point
• The workpiece gripping point distance should be within the gripping force
ranges given for each pressure in the effective gripping force graphs below.
• If operated with the workpiece gripping point beyond the indicated ranges,
an excessive offset load will be applied to the sliding section of the fingers,
which can have an adverse effect on the service life of the product.

Gripping Point
• The workpiece gripping point distance should be within the gripping force
ranges given for each pressure in the effective gripping force graphs below.
• If operated with the workpiece gripping point beyond the indicated ranges, an
excessive offset load will be applied to the sliding section of the fingers, which
can have an adverse effect on the service life of the product.

The effective gripping force shown in the
graphs to the right is expressed as F, which is
the thrust of one finger when all 3 of the
fingers and attachments are in full contact
with the workpiece as shown in the figure
below.

Gripping Point
• The workpiece gripping point distance should be within the gripping force
ranges given for each pressure in the effective gripping force graphs below.
• If operated with the workpiece gripping point beyond the indicated ranges, an
excessive offset load will be applied to the sliding section of the fingers, which
can have an adverse effect on the service life of the product.

Effective Gripping Force
• Indication of effective gripping force
The effective gripping force shown in the
graphs to the right is expressed as F, which is
the thrust of one finger when all 3 of the
fingers and attachments are in full contact
with the workpiece as shown in the figure
below.

Gripping Point
Gripping point
• The workpiece gripping point distance should be within the gripping force
ranges given for each pressure in the effective gripping force graphs below.
• If operated with the workpiece gripping point beyond the indicated ranges, an
excessive offset load will be applied to the sliding section of the fingers, which
can have an adverse effect on the service life of the product.

Effective Gripping Force
• Indication of effective gripping force
The effective gripping force shown in the
graphs to the right is expressed as F, which is
the thrust of one finger when all 3 of the
fingers and attachments are in full contact with
the workpiece as shown in the figure below.

The effective gripping force shown in the
graphs to the right is expressed as F, which is
the thrust of one finger when all 3 of the fingers
and attachments are in full contact with the
workpiece as shown in the figure below.

Gripping Point
Gripping point
• The workpiece gripping point distance should be within the gripping force
ranges given for each pressure in the effective gripping force graphs below.
• If operated with the workpiece gripping point beyond the indicated ranges, an
excessive offset load will be applied to the sliding section of the fingers, which
can have an adverse effect on the service life of the product.

Gripping point
• The workpiece gripping point distance should be within the gripping force
ranges given for each pressure in the effective gripping force graphs below.
• If operated with the workpiece gripping point beyond the indicated ranges, an
excessive offset load will be applied to the sliding section of the fingers, which
can have an adverse effect on the service life of the product.

(1) To set the auto switch, insert the auto switch into the installation groove
of the cylinder as shown below and set it roughly.
(2) Insert the auto switch into the auto switch bracket installation groove.
(3) After confirming the detecting position, tighten the set screws (M2.5)
attached to the auto switch and set it.
(4) Be sure to change the detecting position in the state of (2).

Note 1) When using the 2-color indication type, please make the setting so that the indicator is lit in red to ensure the detection at the proper position of the air gripper.
Note 2) When ordering the air gripper with auto switch in MHS3-32S to 63S series, auto switch mounting brackets are required (shipped together). In addition, when ordering the
auto switch separately, auto switch mounting brackets (BMG2-012) are required. (For details, refer to page 12 of the information (13-E615).)

 The workpiece gripping point distance should be within the gripping
force ranges given for each pressure in the effective gripping force
graphs below.
 If operated with the workpiece gripping point beyond the indicated
ranges, an excessive offset load will be applied to the sliding section of
the fingers, which can have an adverse effect on the service life of the
product.
