The RH56BFX Series is a high‑speed 5‑finger dexterous hand designed for applications where rapid, responsive manipulation is critical. Available in left‑hand (RH56BFX‑2L) and right‑hand (RH56BFX‑2R) configurations, as well as versions with an integrated 2‑DOF wrist (RH56BFXW‑2L / 2R), the BFX Series delivers industry‑leading articulation speeds while maintaining compact, lightweight construction.
Key Features
-
Ultra‑High Speed Articulation – Thumb lateral rotation speed reaches 235°/s, thumb bending speed 150°/s, and four‑finger bending speed reaches an exceptional 570°/s – among the fastest in its class.
-
Compact and Lightweight – Weighing only 540g (standard) or 650g (with wrist), the BFX Series minimizes payload burden on robotic arms.
-
Integrated Force Sensing – Built‑in force sensors provide real‑time feedback for precise, adaptive gripping.
-
Power‑Off Self‑Locking – Maintains position when power is disconnected; no re‑homing required on power‑up.
-
Optional 2‑DOF Wrist – Wrist‑equipped version (DFXW) adds ±27° yaw and ±22° pitch, with load torque rating of 2 N·m (excluding hand weight).
-
RS485 Communication – Simple, reliable integration with most control systems.
