DS-130 Absolute position, rotary Electric Encoder™
The DS-130 is a member of the DS series of Electric Encoders™,
based on Netzer Precision proprietary technology. The Electric
Encoder™ offers many advantages - some unparalleled
Low profile (10mm).
Hollow, floating shaft.
No bearings or other contacting elements.
High resolution and precision.
High tolerance to temperature extremes , shock, moisture, EMI,
RFI and Magnetic fields.
Very low weight.

Protection
The absence of components such as ball bearings , flexible
couplers, glass disc, light sources and detectors, along with very
low power consumption makes the Electric Encoder™ virtually
failure free.
The internally shielded, DC operated Electric Encoder™ includes
an electric field generator, a field receiver, a sinusoidal shaped
dielectric rotor, and processing electronics.
The output signals of Electric Encoder™ are analog Sine / Cosine
representing the rotation angle. The digital outputs are obtained
by further processing - which may be either internal or external
to the encoder.
The combination of precision, low profile, low weight and high
reliability have made Netzer Precision encoders particularly
suitable to a wide variety of critical applications including, but
not limited to medical equipment and aerospace.

The Electric Encoder™ is unique in being holistic, i.e., its output
reading is the averaged outcome of the whole area of the rotor ,
This feature makes the Electric Encoder™ forgiving to mounting
tolerances, ball bearing wander etc.

Digital SSi Interface
Synchronous Serial Interface (SSI) is a point to point serial
interface standard between a master (e.g. controller) and a slave
(e.g. sensor) for digital data transmission.

Digital BiSS-C Interface
BiSS – C Interface is unidirectional serial synchronous protocol
for digital data transmission where the Encoder acts as “slave”
transmits data according to “Master” clock. The BiSS protocol is
designed in B mode and C mode (continuous mode) .The BiSS-C
interface as the SSi is based on RS-422 standards.
