Ingress Protection (IP) Class of Dust- and Drip-Proof Specification
For the dust- and drip-proof specification of TH850A/TH1050A, the ingress protection
(IP) class against dust and water is IP65 or equivalent.
Be sure to perform air purge. Under some operating environment, water or dust may
enter.

•
DO NOT use the entire robot or part of the robot sinking in water. Otherwise, the
water will enter the robot interior.
•
DO NOT use the robot in an environment exceeding the specified IP class against
water and dust. Otherwise, the water or dust may enter the robot interior,
resulting in shortening of the robot life, deterioration of operating accuracy or
mis-operation of the robot.
•
The robot controller does not have dust- and drip-proof specification.
•
For the drip-proof ability against other than water, consult us.
•
The bellows may discolor under some operating environment, which poses no
problem, however, to the dust- and drip-proof performance.
•
Be sure to perform air purge. Otherwise, the dust- and drip-proof performance will
drop.
•
The dust- and drip-proof specification does not mean the explosion-proof structure.
