  • Differential BiSS-C interface (update rate 28 kHz)
  • Sampling rate 18 kHz
  • Geometric dimensions suitable for corresponding RoboDrive servo kits
Designed for use in TQ-RoboDrive ILM Servo Kits and RD Servo Motors, RD85-AKSIM encoders from TQ-RoboDrive provide accurate, high-resolution absolute position data for extremely precise and efficient control of TQ-RoboDrive servo motors. Because they use robust ASIC magnetic sensors rather than optical position sensors, readings are not susceptible to distortion arising from dust and dirt. Multi-turn cycle information is stored electronically and not updated during motion that occurs when the sensor is not supplied with power.
Thanks to the hollow-shaft magnet ring, signals, media and fluids, rays and cables may be passed through the sensor. Designed for integration into space-constrained applications, the sensor system has an axial length of less than 10 mm. RD-AKSIM encoders from TQ-RoboDrive are available in several sizes, all designed to geometrically fit corresponding TQ-RoboDrive servo kits and safety brakes and enable the design of entire actuators and joints.
