What Is a Rotary Encoder? Analysis of Applications and Selection for Domestic Rotary Encoders

I. What is a Rotary Encoder?

Rotary Encoder A measuring device that converts mechanical rotational motion into electrical signal output, primarily used for detection. Angle, rotational speed, direction, and displacement changesIt is one of the most critical sensors in industrial automation systems.

In practical industrial applications, rotary encoders are typically mounted on motor shafts, gearboxes, reels, turntables, or rotating mechanisms. By outputting pulse signals or digital position information, they provide precise feedback to PLCs, motion controllers, or host systems.

Rotary encoders are primarily classified based on their output methods:

• Incremental Rotary Encoder
• Absolute Rotary Encoder (Single-Turn / Multi-Turn)

II. The Role of Rotary Encoders in Industrial Systems

In modern automated equipment, rotary encoders primarily perform the following key functions:

• Motor Speed and Direction Detection
• Position Closed-Loop Control
• Angular Positioning and Repeatability
• Multi-axis synchronization and motion coordination
• Safety Interlock and Condition Monitoring

In fields such as CNC equipment, lifting equipment, metallurgical machinery, automated production lines, packaging equipment, and energy equipment, rotary encoders are virtually indispensable.Essential basic componentsThe

III. Development Background of Domestic Rotary Encoders

For a long time, mid-to-high-end rotary encoders in many critical projects have relied on imported brands. However, as China's automation industry matures, an increasing number of users are beginning to focus on:

• Do domestically produced rotary encoders possess stability?
• Can the imported model be implemented? 1:1 replacement or custom replacement
• Does it support multiple industrial protocols?
• Whether capable of providing long-term supply and local technical support

Against this backdrop,Engineering Capabilities and Application Cases of Domestic Rotary Encodersserve as an important reference standard for selection.
