Sigma 3.1

Heavy-duty modular tool changers

Higher strength, lower weight
and a low profile maximizes robot
load capability, while enhanced
modularity and interchangeability
increases flexibility.

Features and Benefits
Higher payload capacity
up to 350kg
Unique six-sided design
accommodates more utilities
A Sigma 3.1 and Sigma 5.1
common profile provides modularity
and allows for interchangeability of
utility modules
Connects directly to your robot face
plate, eliminating adaptor plate
Low profile reduces inertial forces
Supports wide variety of bus
communication systems

Applications
Spot welding
Material handling
Machine loading/unloading
Mold changing
Docking systems
Pallet coupling systems
Pick and place operations
Press transfer
Not exactly what your application
requires? Applied Robotics can
design a solution that meets your
particular application needs.
