The locking mechanism consists of a male coupling with holes that retain hardened chrome steel ball
bearings. A hardened stainless steel cam is gear driven by a 24V brushless DC servo motor. Tapered pins
located on the Master body mate with holes in the Tool body 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 assembly.

1.2 Tool Plate Assembly
The Tool plate assembly includes an anodized aluminum body, a hardened stainless steel bearing race, and
hardened steel alignment bushings. A sensor target is built into the Tool body so the RTL proximity sensor in
the Master body can sense the Tool presence.
The Tool has (4) flats, Flat A is not used for mounting modules because the servo motor module on the
Master requires the space a module would occupy. The Flat C supports both K series modules and optional
modules with J16 mounting patterns. Flats B and D support optional modules with J16 mounting patterns.
