The Teach Pendant comes in 2 variants: the Standard Teach Pendant, and the 3PE Teach Pendant. The only difference is that the 3PE Teach Pendant has 2 switches on the back, functioning as Positional Enabling Devices.
Mounting
Both Teach Pendants are mounted in the same way. 2 slots on the back, allow them to be situated snugly on top of the mounting bolts that come with the robot.
