2.1 Master Plate Assembly
The Master plate assembly includes an anodized aluminum body, a hardened stainless-steel locking
mechanism, and hardened steel alignment pins. The locking mechanism consists of a cam, a male coupling,
and chrome-steel ball bearings. The Master plate provides (1) or (2) flat sides for mounting optional
modules. Optional modules can be arranged to suit the application.

The air ports provide Lock and Unlock air for the locking mechanism and pass-through air for the end of
arm tooling. An adapter plate assembly provides a standoff for the air ports and a mounting pattern to attach
to the robot arm.
Alignment pins mate with bushings to ensure repeatable alignment during the coupling process. An extreme
pressure grease is applied to the cam, male coupling, ball bearings, and pins to enhance performance
and maximize the life of the Master plate assembly. In some models, the Master plate has tapered
alignment pins, and in the other models, such as the QC-11, the Master plate has hardened stainless steel
alignment bushings.
A cover plate that attaches to the Master protects the internal locking mechanism during shipment. This
cover plate can be removed during installation if replaced by an interface plate. Refer to
for details.
2.2 Tool Plate Assembly
The Tool plate assembly includes an anodized aluminum body and a hardened stainless-steel bearing
race. The Tool plate provides (1) or (2) flat sides for mounting of optional modules. Optional modules
can be arranged to suit the application. In some models, the bearing race or Tool plate body has integrated
alignment holes or bushings, and in other models, such as the QC-11, the Tool plate has hardened steel
alignment pins.
The Tool plate is equipped with pass through air ports to supply air to the end of arm tooling.
