This part of ISO 9409 defines the main dimensions, designation and marking for the circular mechanical interface (form A). It is intended to ensure the exchangeability and orientation of hand-mounted end effectors.
This part of ISO 9409 does not define other requirements of the end effector coupling device.
ISO 9409-1 does not contain any correlation of load-carrying ranges.
The mechanical interface specified in this part of ISO 9409 will also find applications in simple handling systems which are not covered by the definition of manipulating industrial robots, e.g. pick and place or master-slave units.
