Encoders play a crucial role in industrial automation and control systems. With continuous technological advancements, the types and functionalities of encoders are constantly evolving. This article provides the latest 2025 encoder buying guide to help you understand the characteristics of different types of encoders, key selection factors, and top brand recommendations in the market, enabling you to make informed purchasing decisions.
Types of Encoders
Encoders are primarily divided into two main categories: incremental encoders and absolute encoders.
Incremental Encoders
Features: Output position changes through pulse signals, suitable for relative measurement of speed and position.
Applications: Commonly used in scenarios requiring simple position feedback, such as elevator control systems.
Absolute Encoders
Features: Provide a unique code for each position, capable of retaining position data after power loss.
Applications: Suitable for scenarios requiring precise position positioning, such as robot joint control.
Additionally, there are linear encoders and rotary encoders. Choose the appropriate type based on your specific application needs.
Key Factors in Choosing Encoders
When selecting an encoder, consider the following key factors:
Resolution: Determines the fineness with which the encoder can detect position changes. Higher resolution offers more precise positioning.
Accuracy: Influences the overall control precision of the system. Selecting a high-accuracy encoder can enhance system performance.
Interface Type: Ensure the encoder's output interface is compatible with your existing system. For example, incremental encoders typically use A, B, and Z signal outputs.
Operating Environment: Consider the encoder's operating temperature, humidity, dustproof and waterproof ratings to ensure stability in specific environments.
Brand and After-Sales Service: Choose reputable brands with excellent after-sales support to ensure product quality and ongoing support.
