1.1  Master Plate Assembly

The Master plate assembly includes an anodized aluminum body, a hardened stainless‑steel locking 
mechanism, and hardened steel alignment pins (see 

Figure 1.1

). The Master plate has (4) flats for mounting 

optional modules with a J16 pattern. Flat “C” has a mounting pattern for a K series module. The locking 
mechanism consists of a cam, a male coupling, and chrome‑steel ball bearings. A 100 mm BC mounting 
pattern is machined into the Master plate for mounting to a robot arm or a interface plate. Refer to 

Section 8—Drawings 

for mounting details.

(2) 90° elbows with push tube fittings are included to supply air pressure for coupling and uncoupling the 

Tool Changer. The Master plate assembly is equipped with (16) M5 pass‑through air ports and (4) G 1/8 

(BSPP) pass‑through air ports.

Tapered pins, located on the Master plate, mate with bushings in the Tool plate 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.

Proximity sensors are designed into the body of the Master plate to detect Lock and Unlock positions of the 

locking mechanism. The sensors provide “lock” and “unlock” position signals to the customer’s process 
controller. The sensors can be ordered separately.
