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.
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.

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 SSi 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.
