DS-25-16

Absolute Position, Rotary Electric Encoder™

The DS-25-16 is a member of the DS series, based on Netzer Precision Electric Encoder™ technology. This state-of-the-art encoder technology offers many advantages, some unparalleled:

• Low profile (7 mm)

• Hollow, floating, shaft

• No bearings or other contacting elements

• High precision

• High tolerance to temperature, shock, moisture EMI, RFI and magneticfields

• Multiple protocol interface options

• Continuesoutput

Demanding application suited to the DS-25-16 include: Aerospace, medical, instrumentation, automation, etc.

The holistic structure of the Electric Encoder™ provides generous mounting tolerance, thus obviating the need for internal ball bearings.

The absence of ball bearings and components such as flexible couplers, glass disc, light sources and detectors, along with very low power consumption makesthe DS-25-16 encoder virtually failure free.

The internally shielded, DC operated DS-25-16 includes an electric field generator, a field receiver, a sinusoidal-shaped dielectric rotor, and processing electronics.
