Sigma 3.1 Tool Changer

sigma3-1_cornerWhen it comes to robotics, flexibility is critical. That’s why Applied Robotics has designed our Sigma 3.1 robotic tool change systems to perform multiple functions in a single work cell easily and efficiently.

The Sigma 3.1 robotic tool changer offers a high strength to weight ratio and a low profile to maximize robot load capability, while enhanced modularity and interchangeability increase flexibility.

Features and Benefits

  • Unique wear-compensating, fail-safe cam latching mechanism
  • Emergency manual unlock feature
  • Higher payload capacity – up to 360 kg ( 794 lbs)
  • 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
  • Eliminates adaptor plates for lower weights, and increased strength and efficiency
  • Low profile reduces inertial forces
  • Supports wide variety of servo tools and bus communications
