RGD Series Direct Drive Rotary Gripper RGD-5-14 RGD-5-30 The RGD direct-drive electric rotary gripper of DH-Robotics adopts a direct-drive backlash-free rotation module to improve the rotary accuracy, and thus is perfectly suited for high-precision manufacturing applications. Installation 1. Front installation: use front screw holes for installation 2. Bottom installation: use bottom screw holes for installation Product Features ● Zero Rotary Backlash High Repeatability ● High Dynamic Response High-speed Stability ● All-in-one Design Power-oﬀ Protection The RGD series adopts direct-drive The precision direct-drive technology, The gripper adopts the design of rotary motors to realize zero rotary coupled with DH-Robotics' excellent integrating the dual servo system of backlash and a rotary resolution of up drive control, realizes perfect control gripping and rotation with the drive to 0.01°, which applies to rotary of gripping and rotation. The rotation control module, which is smaller and positioning scenarios in semiconduc- more compact, and applies to more scenarios. Brakes are optional to meet the requirements of various applications. Application With the direct-drive technology, the RGD gripper can provide greatly improved rotary accuracy, which can be used in scenarios such as the high-precision positioning assembly, transport, and deﬂection correction of 3C electronics and semico
