In modern industrial automation, construction machinery, robotics, and intelligent equipment,Incremental EncodersIt is a key sensor for measuring the position, velocity, and direction of rotational or linear motion. Its output pulse signal provides real-time feedback directly to control systems, making it an indispensable measurement and control component in various automation systems. This article covers: Official content released on the official websiteSuitable for engineering selection and technical reference.

One,Incremental Encoders简介

Incremental encoders detect shaft rotation or guide rail movement to output continuous pulse signals. Their features include:

• Real-time motion feedbackProvides precise pulse signals for speed and position control.
• High-resolution designSupports micrometer-level or angular resolution measurements
• Multi-interface supportCompatible with TTL, HTL, RS422, SSI, RS485, and other signal interfaces
• Wide range of applicationsIndustrial automation production lines, robots, multi-axis machinery, logistics conveyance systems, and construction machinery

Incremental encoders do not retain absolute position after power loss, but can resume precise measurement after reset or reference point calibration, making them suitable for most industrial control systems.

II. Advantages of Domestic Production

XWDI offers a full range of domestically produced incremental encoders with the following advantages:

• Multiple structural typesRotating shafts, hollow shafts, solid shafts, multi-turn rotation, and wire displacement
• Customized InstallationFlange, shaft diameter, and mounting method can be customized according to project requirements.
• High Reliability DesignWithstands extreme temperatures, dustproof, waterproof, and vibration-resistant, meeting the demands of harsh industrial environments.
• Multi-Communication ProtocolSupports SSI, RS485, CANopen, Profinet, Ethernet
• Domestic Supply ChainFast delivery, shorten project cycles, and increase localization rates

Through domestic production solutions, incremental encoders can replace imported products, ensuring both high-precision measurement and engineering reliability.

III. Typical Application Scenarios

Incremental encoders are widely used in:
