The HAT Hollow and Standard Harmonic Servo Rotary Actuators support harmonic drives of models 11, 14, 17, 20, 25, 32, 40, 50, and 58, with rated torque from 4 N·m to 1200 N·m and outer diameters ranging from 62 mm to 220 mm.They feature multi-turn absolute encoders with Tamagawa protocol:Single-turn 17-bit, multi-turn 16-bit, or Single-turn 23-bit, multi-turn 16-bit.Custom dual-encoder configurations are also available. The harmonic actuators can be directly mounted via the end face, making them ideal for lightweight or space-constrained applications.
