Miniature Encoder

The marketplace for encoder products is getting increasingly competitive with focus on target product segment where each product has distinct value propositions against competition. Today, sourcing engineers are targeting cost effective solutions while keeping up with the technology and finding the right encoder that meets all or most priorities. In most circumstances tradeoff decision has to be made in deciding the best components that meet all design requirements at an affordable cost. However one of the key challenges faced by engineers in finding the right encoder solution is size. Traditionally, industrial encoder was perceived to be not just rugged and heavy duty but also larger in overall diameter and height. Most industrial encoder manufacturers are gearing towards building larger encoder for the industrial market and very often the miniature encoder market was placed at a lower priority. As a result the availability of miniature encoder that could potentially serving many high volume industrial applications becomes increasing challenging to find. The challenge becomes even greater once you start adding more values and features to the product such as adding more resolution and adding an index channel to the product. Therefore, finding an encoder with the combination of high resolution, small, optional index channel, and at an affordable cost could be as challenging as finding a very inexpensive industrial heavy duty encoder.

The Avago AEDR-8400 series encoder was regarded as the industry smallest encoder module you can find but if you are looking for a miniature kit or housed encoder solution, ETIC-Avago may have a solution for you. The latest 18M or 18S series incremental kit encoder is now available through ETIC-Avago for the US market. The following is the overview of the 18M and 18S series miniature encoder from ETIC-Avago manufactured by our affiliates Nemicon in Japan. Please contact one of our ETIC- Avago staffs for more information about this encoder or visit www.etic-avago.com for more information.

18M Series

This miniature series encoder is only 18mm in diameter, yet provides resolutions from 100 to 1600 CPR. The standard configuration is 3 channels, A, B, and Z. The kit version is only 13mm in height, thus requiring minimal mounting space. The open collector output units may be operated from supplies from 4.5V to 13V, providing added flexibility in interfacing to external electronics. A line driver output option is also offered for use in noisy environments, or for driving long cables.

18S Series

This miniature series encoder is only 18mm in diameter, yet provides resolutions from 100 to 1600 CPR. The standard configuration is 3 channels, A, B, and Z. The shaft version (18S) is only 22.5mm overall, and is sealed to provide an IP rating of 50. The open collector output units may be operated from supplies from 4.5V to 13V, providing added flexibility in interfacing to external electronics. A line driver output option is also offered for use in noisy environments, or for driving long cables.
