Robot hand
Please install a check valve in the air-pressure circuit so that the gripper will not release a workpiece even if the air pressure drops down.
When the jaw stroke is detected by the reed switches, mount reed switched on the grooves on the outer periphery of the product. Up to 4 reed switches can be mounted.
In case proximity switches are used for direct detection of jaw stroke, please purchase proximity switch brackets additionally.
The material of internal seals of grippers is nitrile rubber. If the fluororubber seals are needed, please consult Kitagawa distributor.
