TRPC-A3→Low-error assembly processes
The TRPC series combines two major components:
➤A3 Torque Arm (350A3 / 650A3 / 900A3) – Available in three lengths to suit different workspace and workpiece sizes
➤CL-A3 Digital Management System – Offers touch-screen guidance, task control, and real-time torque monitoring
Together, they form the TRPC-350A3 / 650A3 / 900A3 models, differentiated by torque arm length and coverage area.
The TRPC series is a smart screwdriving solution integrating error-proofing, torque monitoring, and guided control. Its intuitive touchscreen interface, screw detection sensors, and torque data logging enable precise and consistent fastening, making it ideal for industries demanding high-quality and low-error assembly processes.
