Netzer – Master of Surgical Robots (04/2022)

Netzer’s proven miniature DS-16 Electric Encoder™ is a reliable and high-precision encoder that provides excellent and repetitive performance and its miniature dimensions are specifically designed to be incorporated in the design of high-end surgical robots, allowing accurate and reliable measurement of the robotic arms’ exact position during the entire surgical procedure.
The DS line of encoders is immune to magnetic fields and resistant to “surgical energy” and provides a stable position measurement under the demanding environment of remote surgery, meeting the highest standards required from the surgical robots by the certification authorities.


  • Small size/diameter and low profile
  • High precision
  • Resistance to magnetic fields and “Surgical Energy”
  • Built-In Test (BIT) functionality


  • Netzer DS-16 Absolute Position Electric Encoder™ was incorporated in the robotic Master controller with accuracy better than 0.02deg.
  • Compact form, low profile, lightweight, and hollow-shaft: Allow easy integration into the robotic Master.
  • Frame-less and contact-less with a negligible weight introduce no extra inertia(load) to the robotic system, resulting in long-lasting operational life
  • Immunity to magnetic interference: This can be located very close to the frameless-motor magnets.
  • High resolution 16 bit and better than 0.02 deg accuracy for smooth rotation with high repeatability of no more than 1 count.
  • The DS series is Smart Sensors featuring special safety algorithms with real-time BIT (Built-In Test) over SSI or BiSS, zero position assignment, and more.
