RD70-AKSIM encoders from TQ-RoboDrive provide accurate absolute position data with high resolution for the precise, efficient control of TQ-RoboDrive servo motors. The encoders feature highly robust magnetic ASIC sensors, providing significantly better resistance to dust, dirt and other disruptive elements. Multiturn cycle information is stored electronically but is not updated during motion when there is no power supply to the sensor.
Thanks to the hollow-shaft magnet ring, signals, media and fluids, rays and cable can be passed through the middle of the sensor. With an axial length of less than 10 mm and featuring off-axis reading heads, the sensor system was designed for integration into space-constrained applications. RD-AKSIM encoders are available in three sizes and have been designed to geometrically fit corresponding TQ-RoboDrive servo kits and safety brakes, allowing for the design of entire actuators and joints.
