Warning
① When the moving of work pieces pose a danger to personnel,
or there is a danger of fingers’being caught in a gripper, etc.,
implement safety measures such as mounting of protective
covers.
② If circuit pressure drops due to a power failure or trouble with
the air supply, etc., there is a danger of work pieces dropping
because of reduced gripping force. Implement drop prevention
measures to avoid human injury and equipment damage.
Warning
① Keep the holding point within the specified range of the
holding distance.
1. When the holding point distance becomes large, the
finger attachment applies an excessively large load to the
finger sliding section, causing excessive play of the
fingers and possibly leading to premature failure.
2. Attachment should be designed as light and short as
possible.
3. Long and heavy attachment increases the inertia force to
open or close the fingers. It may cause unsteady
movement of fingers and have an adverse effect on life.
② Select the model whose holding force is sufficient against work
weight.
③ Do not use in applications where excessive external force or
impact force may be applied to gripper.
④ Select a model with a sufficient finger opening width for the
work.
1. Holding may become unsteady due to variations in
opening/closing width or work diameter.
2. When using the auto switch, the detection may not be
reliable Refer to “Auto Switch Hysteresis”and set the
stroke including the hysteresis length for reliable switch
function.
Warning
① Do not drop or dent the gripper when mounting.
Slight deformation can cause inaccuracy or a malfunction.
② Tighten the screw within the specified torque range when
mounting the attachment.
Warning
① Avoid twisting the fingers when mounting the attchment.
Any damage to fingers may cause a malfunction and reduce
accuracy.
② Avoid external force to fingers.
Fingers may be damaged by continual lateral or impact
loads.
Provide clearance to prevent the work or the attachment
from striking against any object at the stroke end.
③ Adjust the holding point so that excessive force will not
be applied on fingers when inserting the work.
④ Control the opening/closing speed with the speed
conroller to avoid excessive high-speed operation.
Continuous opening and closing of the fingers at high
speed may cause deterioration of the repeatability and
shorten the product life.

Model selection Method
1. Confirmation of gripping force
�Calculation required grippingforce(kg)
�External gripping�Friction coefficient(μ)�Extra margin⒜
�Although differences will exist dependingupon factors such as shape and thecoefficient of friction between the attach-ments and the work pieces, a modelshould be selected which will provide agripping force at least 10 to 20 timesgreater that the work piece weight.
�Furthermore, in cases where high acceleration orimpact, etc. will occur, it is necessary to alllow aneven greater margin.
3. Selection of Model from gripping force graph
4. Model selection explanatory drawing
�Gripping point distance
L = 2cm
�Operating pressure : 0.3MPa
�Note
1MPa ≒ 10.2kgf/cm2
1N ≒ 0.102kgf
1kgf/cm2 ≒ 0.098MPa
1kgf ≒ 9.8N
�Selection of Ex 1
※ In case of selecting NFH2-16D.A gripping force of 15.7N is obtained fromthe intersection point of gripping pointdistance L=2cm and pressure of 0.3MPa
※ The gripping force is 16 times greater thanthe work piece weight and therefore satisfiesa gripping force setting value of 10 times ormore.
�Selection of Ex 2
※ In case of selecting NFH2-20D.A gripping force of 22N is obtained from theintersection point of gripping point distanceL=2cm and pressure of 0.3MPa
※ The gripping force is 22 times greater thanthe work piece weight and therefore satisfiesa gripping force setting value of 20 times ormore.
2. Calculation required gripping force
�Calculation required grippingforce = 0.1(kg)
�External gripping�Friction coefficient = χ(μ)�Extra margin⒜ = 4
�Required gripping force(F)
F = mg/(2μ) * a
- g : (9.8 m/s2)
�Example1When it is desired to set the gripping force at 10times or more above the work piece weight.Required gripping force(μ= 0.2)
F = 0.1kg * 9.8 m/s2 * 10 = 9.8(N)
�Example 2When it is desired to set the gripping force at 20times or more above the work piece weight.Required gripping force(μ= 0.1)
F = 0.1kg * 9.8 m/s2 * 20 = 19.6(N)
�When gripping a work piece as in the
figure to the left, and with the following
definitions,
F : Gripping force(N)
μ: Coefficient of friction between the
attachments and the work piece
m : Work piece mass(kg)
g : Gravitational acceleration(= 9.8m/s2)
mg : work piece weight(N)
the conditions under which the work
piece will not drop are
2 * μF > mg
� Number of fingers
and therefore,
F > mg / 2μ
With “a”representing the extra
margin, F is determined by the
following formula :
F = mga / (2μ)
Note) It is necessary to alllow a greater
margin for high accelerations and
strong impacts.
