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 base unit. Up to 6 reed switches can be mounted. This model does not support stroke check with Proximity switches.
The material of internal seals of grippers is nitrile rubber. If the fluororubber seals are needed, please consult Kitagawa distributor.
