Rotary electric encoder increases reliability

Netzer's DS-25 lightweight, miniature absolute rotary encoder provides high-resolution positions with a miniature-to-wide diameter hollow shaft. Fewer components increases reliability.

Netzer's new encoder's structure provides mounting tolerance, which obviates the need for internal ball bearings. The lack of bearings and components such as flexible couplers, glass discs, light sources, and detectors, along with low power consumption makes the DS-25 encoder less likely to fail.


Courtesy of Netzer The internally shielded encoder includes an electric field generator, a field receiver, a sinusoidal-shaped dielectric rotor, and processing electronics. The outputs signals of the DS-25 Electric Encoder are analog sine and cosine, representing the rotation angle, incremental or absolute position.

The DS-25 is well-suited for demanding applications such as aerospace, medical, instrumentation, and automation.

Its key features include:

  • Lightweight, miniature absolute rotary encoder

  • Hollow, floating shaft

  • No bearings or other contacting elements

  • High precision

  • High tolerance to temperature, shock, moisture EMI & RFI

  • Insensitive to magnetic fields

  • Total weight of 4 gm

  • Low profile of 7 mm
  • Analog sin and cos, digital SSi or digital AqB+I outputs
