Magnetic encoder is reliable and easy to use
Avago Technologies is launching a new series of compact non-contact magnetic encoders for use in industrial applications that operate in harsh conditions. Avago's AEAT-60xx series of magnetic encoders are reliable, cost-effective and easy-to-use for angular detection within 360-degrees. Moreover, this magnetic encoder is suitable for use by designers of industrial flow meters, knob controls and a variety of other rotary encoder applications where space is limited.
The AEAT-60xx series of non-contact magnetic encoders, which comes in a cylindrical package that is 23mm in diameter and 23 mm tall, enables angular detection in a small form-factor package. Priced competitively at about half the price of absolute encoders available from other housed absolute encoder suppliers, the AEAT-60xx encoder series units are designed to provide reliable performance in industrial applications that operate under high temperatures.
Today's industrial designers want smaller, more reliable encoders, as end products continue to shrink in size and the required capacities of these devices grow. Consequently, designers are looking for smaller absolute encoders to use in their feedback system that are more accurate, more reliable and at a lower cost. Avago's AEAT-60xx magnetic encoders were developed to meet these design requirements.
Based on magnetic technology, the AEAT-60xx series has the ability to provide absolute angle detection upon power-up, with a resolution of 0.0879 degrees (12-bit versions) or 0.35 degrees (10-bit versions), which are equivalent to 4096 and 1024 positions per revolution, respectively. Moreover, there is no upper speed limit - the only restriction is that there will be fewer samples per revolution as the speed increases.
Avago's AEAT-60xx magnetic encoders come complete with housing and are available with 4, 6 and 8mm shaft diameters. A PCB version without the housing is also available.
Features
- Easy assembly, no signal adjustment required
- Contactless sensing technology

- Code monotony error = +/-1 LSB
- RoHS-compliant
The AEAT-60xx series magnetic encoders are available in the following configurations:
- AEAT-601x-A06 (6mm standard shaft) available in 10 or 12 bits
- AEAT-601x-A0x available in 4mm and 8mm shafts
- PCB form without housing is available upon request
Samples and production quantities are available now through Avago's direct sales channel and worldwide distribution partners.
