PHD Pneu-Connect X1 Pneumatic Grippers
PHD, Inc.

PHD Pneu-Connect X1 is a cost-effective system providing easy pneumatic end-effector integration for collaborative robots. Pneu-Connect features embedded directional control valves for control of an end-effector through the robot’s tool port. The system easily attaches to the robot arm and allows for interfacing with the robot peripherals programming. Five models of PHD pneumatic grippers are currently offered as single gripper solutions. Additionally, an analog sensor choice is now available for the Series GRH kits. The analog sensor provides jaw position feedback for increased programming functionality.

The power density of pneumatics allows for a superior performance to weight ratio when compared to some electric alternatives. This inherent property allows for lighter, non-payload robbing end-effectors, ideal for robotic applications. Additionally, when properly controlled, the compressibility of air provides intrinsically safe, back-drivable actuation capability.
