In this webinar — Encoder integration in 2016: New modes of installation, networking, and more — we cover the latest in rotary position encoders. We explore where mechanical, optical, magnetic, and capacitive encoders excel, and what features have been added in the last few years. Next, we review the physical permutations available to engineers for rotary position encoders — including seal options, mounting and bearing options, housings, ratings, and modular setups that have become increasingly customizable. Then we give some examples of consumer-grade designs, industrial setups, and commercial feedback applications, and which physical permutations are most common for each. Finally we get into control electronics and the encoder signals themselves … and compare issues and capabilities and modes of measuring in resolution, interpolation, and signal processing. We define and explain commutation channels, prevention of signal degradation, the functions of automatic gain control (AGC), signal processing, and control integration as it relates to encoders in general.

1. Do you need a bearing-less encoder?

24. #DWwebinar
❑ Excessive radial and axial loads (5-40 lbs typical)
❑ Extreme shock and/or vibration (50 g @ 11ms typical)
❑ Extreme temperatures (-20°C – 80°C typical)
❑ Contaminants (shaft seal IP64 typical)
- Factors that can cause bearing wear

25. #DWwebinar
- High-speed application
❑ Most bearing encoders rated 6,000 - 10,000 RPMs
❑ Bearings are usually the limiting factor

26. #DWwebinar
- Cost-sensitive application

27. #DWwebinar
2. Do you have space constraints?

28. #DWwebinar
3. Are contaminants present?

29. #DWwebinar
4. Is sensor-to-disk air gap a risk factor?

30. #DWwebinar
Some magnetic sensors are very tolerant of wide
air gap and shaft misalignment

31. #DWwebinar
❑ High accuracy
❑ High resolution
❑ Tolerant of
magnetic fields
Optical + Bearing
❑ Tolerant of contaminants
❑ Tolerant of high shock and
