What is the difference between absolute and incremental encoders?
Encoders are crucial parts of motion control systems because they translate mechanical motion into electrical data. These signals give exact details regarding the location, speed, and orientation of a linear axis or rotating shaft. Encoders enable various applications, from medical devices and automotive systems to industrial automation and robotics, by precisely measuring and controlling motion.
The market is dominated by two main encoder types: absolute and incremental. Although both are essential to motion control, their benefits uses, and working principles differ.
The possibilities of incremental encoders are best demonstrated by Eltra Incremental Rotary Encoders, which are well-known for their excellent quality and dependability. These devices provide exact position feedback, making it possible to precisely regulate motion in various industrial applications.
Understanding Encoders
An encoder is a device that transforms mechanical motion—like rotation or linear displacement—into electrical impulses. A control system can then decipher these signals to ascertain the motion’s position, speed, and direction. Encoders are crucial to many applications, including robotics, machine tools, and industrial automation.
The Operation of Encoders
To detect and measure motion, encoders usually use optical or magnetic technology. A revolving or moving disk with opaque and transparent parts interrupts light emitted from a light source in optical encoders. A sensor picks up the ensuing pattern of light and dark and produces an electrical signal in response. In contrast, magnetic encoders use a sensor and a magnetic field to identify variations in magnetic flux brought on by a moving magnetic element.
Common Encoder Types
- Rotary Encoders: Both rotational speed and angular position are measured using rotary encoders. They are frequently used in rotary motion-related applications such as robotic joints, servos, and motors.
- Linear Encoders: Linear displacement is measured by linear encoders. They are employed in automated assembly lines, 3D printers, machine tools, and other applications that call for accurate linear motion.
Absolute Encoders
How They Work
Absolute encoders directly encode the position information into a digital code. Each position on the encoder’s shaft or scale corresponds to a unique binary code. This code is immediately available upon power-up, eliminating the need for homing or reference point procedures.
Advantages
- Immediate Position Information: Absolute encoders provide accurate position information as soon as they are powered on, saving time and increasing productivity.
- No Need for Homing or Reference Points: By directly encoding the absolute position, absolute encoders eliminate the need for complex homing procedures, which can be time-consuming and prone to errors.
- Precise Positioning: The direct encoding of position information allows for accurate positioning and repeatability, making absolute encoders ideal for applications that require high accuracy.
Disadvantages
- Higher Cost: Absolute encoders are generally more expensive than incremental encoders due to their more complex circuitry and higher component count.
- More Complex Circuitry: The circuitry required to decode the absolute position code is more complex than that of incremental encoders.
Incremental Encoders
How They Work
Incremental encoders generate a series of pulses for each incremental movement of the shaft or scale. These pulses can be counted to determine the relative position from a reference point. The control system can calculate the distance traveled or the angular rotation by counting the number of pulses.
Advantages
- Lower Cost: Incremental encoders are generally less expensive than absolute encoders due to their simpler design and lower component count.
- Simpler Circuitry: The circuitry required to process the pulse signals from incremental encoders is simpler than that of absolute encoders.
- Suitable for Relative Positioning: Incremental encoders are well-suited for applications that require relative positioning, such as controlling the speed and acceleration of motors.
Disadvantages
- Requires Homing or Reference Points: Incremental encoders must be homed or referenced to establish a starting point. This process involves moving the encoder to a known position and resetting the pulse counter.
- Potential for Accumulated Error: Over time, small errors in pulse counting can accumulate, leading to inaccuracies in position measurement. To mitigate this, incremental encoders often incorporate advanced signal processing techniques to reduce accrued error.
Key Differences
Position Information
- Absolute Encoders: These encoders directly output a digital code representing the absolute position. This code is unique for each encoder’s shaft or scale position. As a result, the encoder’s position can be determined immediately upon power-up without homing or referencing procedures.
- Incremental Encoders: These encoders generate a series of pulses for each incremental movement. The position is calculated by counting the number of pulses from a reference point. The encoder must be homed or referenced to a known position to determine the absolute position. This process involves moving the encoder to a specific position and resetting the pulse counter.
Power-Up Behavior
- Absolute Encoders: Absolute encoders provide immediate position information upon power-up. This is a significant advantage, as it eliminates the need for lengthy homing procedures and allows for faster system startup times.
- Incremental Encoders: Incremental encoders require homing or referencing to establish a starting point. This process can be time-consuming, especially for systems with multiple axes or complex motion profiles.
Cost and Complexity
- Absolute Encoders: Absolute encoders are generally more expensive than incremental encoders due to their more complex circuitry and higher component count. The circuitry required to decode the absolute position code is more sophisticated and requires additional components, such as a microcontroller or FPGA.
- Incremental Encoders: Incremental encoders are simpler in design and typically require fewer components. The circuitry processing the pulse signals is less complex, leading to lower manufacturing costs.

AI and Regtech: The Smart Brains Behind the Scenes
If payments are the heartbeat, artificial intelligence is the brain. AI is supercharging finance in two key ways: providing insights and managing risk.
- Credit Scoring and Lending: How do you lend to someone with no formal credit history? FTAsiaFinance technology leverages AI to analyze alternative data—phone usage patterns, utility bill payments, even social media activity—to create a financial identity for the “unbanked.” This is a game-changer for financial inclusion.
- Regulatory Technology (Regtech): For banks, complying with a maze of international and local regulations is costly and complex. AI-powered regtech tools can automate compliance checks, monitor transactions for fraud in real-time, and generate reports, saving institutions millions and making the system safer for everyone.
Open Banking and APIs: Unleashing Financial Data
Open banking is the simple but powerful idea that you own your financial data and should be able to share it securely with third-party apps to get better services. This is made possible through Application Programming Interfaces (APIs)—digital handshakes that allow different software to talk to each other.
- Imagine this: Instead of manually uploading bank statements for a mortgage application, you simply grant a lender permission to access the necessary data directly from your bank—securely and instantly. This seamless flow of information is empowering consumers and fostering a new wave of innovative financial products.
Blockchain, DeFi, and the CBDC Frontier
Perhaps the most futuristic—and debated—area of innovation lies with blockchain. While cryptocurrencies get the headlines, the underlying technology has profound implications.
- Cross-Border Payments: Traditional international money transfers are slow and expensive. Blockchain-based solutions can settle these transactions in seconds at a fraction of the cost, a huge benefit for a trade-heavy region like Asia.
- Central Bank Digital Currencies (CBDCs): Countries like China (with the digital yuan), India, and Thailand are already piloting their own sovereign digital currencies. Unlike volatile cryptocurrencies, a CBDC is digital cash issued and backed by the central bank, offering a new tool for monetary policy and financial stability.
Navigating the Regulatory Landscape
With great innovation comes the need for great responsibility. Asia’s regulators are walking a tightrope: they want to encourage the immense benefits of fintech while protecting consumers and ensuring financial stability. The approach varies widely.
- Sandbox Environments: Many countries, like Singapore and Hong Kong, have created “regulatory sandboxes.” This allows fintech startups to test new products in a controlled environment with real customers, without immediately facing the full burden of financial regulations.
- Balancing Act: The key challenge is finding the right balance. Too much regulation too soon can stifle innovation. Too little can lead to consumer harm and systemic risk. The ongoing evolution of this regulatory context is a critical part of the FTAsiaFinance technology story.
