Pneumatic or Servo Gripper... which one is right for you

nnnn

FLEXIBILITY

nnnn

Am 1 handling different sized parts?	• typically small finger travel • different sized parts may require multiple grippers
Do 1 need more than one force?	• multiple grip forces require add-ons
Do 1 need different grip speeds?	• more than one speed requires add-ons
What are my future gripping needs?	• for dedicated process

nnnn

■ finger travel adjustable

nnnn

within large range

nnnn

programmable to allow

nnnn

multiple grip forces

nnnn

a single movement can

nnnn

have multiple grip speeds

nnnn

■ for adaptable processes

nnnn

How do I control

nnnn

positioning?

How do I control

nnnn

force and grip speed?

nnnn

NEUMATIC

nnnn

■ unable to control position

nnnn

without add-ons

nnnn

■ multiple stop positions

nnnn

can be programmed

nnnn

Do I need position

nnnn

feedback?

nnnn

Do I need to be

nnnn

able to confirm an

nnnn

object is being

nnnn

gripped?

What are my weight * grippers are lighter • grippers are heavier

nnnn

constraints?

nnnn

Can I use compressed

nnnn

air or is it available

nnnn

in my process?

nnnn

requires air

nnnn

■ doesn't require air

nnnn

What is my

nnnn

temperature

nnnn

environment?

nnnn

• some grippers are

nnnn

able to operate in hot

nnnn

or cold temperatures

nnnn

Can it operate

nnnn

in a sterile
