Festo DHAS-GF-120-U-BU 3998959 Adaptive Gripper Finger 120mm

Festo DHAS-GF‑120‑U‑BU is a flexible, adaptive gripper jaw for pneumatic gripper systems. It is made of TPE‑U(PU) material in blue and uses the Fin Ray Effect® – a bionic principle inspired by a fish's tail fin. This structure allows the gripper jaw to wrap gently around the workpiece instead of simply pressing against it, providing low‑vibration transport and impact‑free placement. Ideal for handling sensitive surfaces, delicate materials, and irregularly shaped objects.

Applications:

• Handling delicate or fragile components (e.g., electronics, glass, fruit)

• Pick‑and‑place and assembly automation for sensitive surfaces

• Material handling in packaging and life sciences

• Integration with Festo pneumatic grippers (e.g., HGPL, HGPD, HGPT series)
