Even though the Netzer Electric Encoder™ is inherently absolute, there is still a market requirement for incremental AqB+Index output – similar to that of classical optical encoders.
Netzer Precision Motion Sensors now offers its standard Electric encoder™ with an AqB+Index output option which is obtained by processing the internal sine/cosine analog signals. Unlike in optical encoders which may miscount as a result of contamination, the structure and principle of operation of the Electric Encoder™ provides a reliable output and makes this concern irrelevant.
Netzer Encoder Product Family
The Electric Encoder™ with AqB+Index output is also unique in that the number of pulses per rotation and index pulse parameters can be factory tailored. This combines with other advantages such as durability, hollow shaft and low profile. The AqB+Index conversion electronics comes as external module in some of the encoders and is included internally in others.
Advantages of Netzer Electric Encoders™ include:
Simple, robust structure with a virtually no- failure- mechanism
Generous mounting tolerances
Very low weight, inertia, and profile (=<10mm)
Ring shaped, hollow shaft with a wide range of diameters
Absolute position output over 360° rotation range
Precision to 0.001° in selected models
Default operation range from -55°C to +125°C
Dual and triple redundancy options
No magnetic signature
High tolerance to condensation and contaminants
Insensitivity to EMI/RFI and magnetic fields
Low power consumption
Wide variety of position feedback protocols
Netzer Precision Motion Sensors has taken a revolutionary position sensing technology, originally developed for harsh environment specialized applications, and made it available for today’s broader range of defense, homeland security, aerospace and instrumentation motion control requirements. Standard and customized rotary and linear electric encoders are also applicable to medical, automotive and a wide range of other applications.
