Single-Turn, Geared Single-Turn and Dual (Multi-turn) Resolvers

• Absolute shaft position
• No internal electronics
• Brushless resolver
• High-resistance to shock and vibrations
• NEMA 13 housing provides protection against water, mist, oil, and dust
• Broad temperature range, -67º F to 248º F (-55º C to 120º C)
• Remote ratiometric resolver decoder provides highly noise-immune encoder

RL100 Resolver--The Workhorse of the Industry
AVG Automation's model RL100 resolver is the most rugged resolver in the industry today.  AVG Automation has over 25,000 of these resolvers operating with extreme reliability in highly demanding applications in automotive, can-manufacturing and packing industries.  Rugged, industrial housing, heavy-duty, double row, ball bearing and an internal flexible coupling lend to an extremely reliable design.

Advantages of Resolvers vs. Encoders

The decision of whether to use a resolver or encoder depends entirely on the application. The factor that has the greatest impact on the decision is the operating environment. The environmental integrity of a brushless resolver is unchallenged. Being simple rotary transformers, resolvers can take more abuse than optical encoders.

Resolvers exhibit no significant wear or aging. This is especially important when the operational temperature is below freezing or above 150 F. Under these extremes, the only choice is to use a resolver. The operating temperature of a typical resolver ranges from -67 F to +248 F. Resolvers also survive in conditions of severe mechanical shock and vibrations, excesses in humidity, oil mists, and exposure to coolants and solvents.
