Incremental encoders output pulses relative to movement, requiring a homing sequence. Absolute encoders provide a unique digital code for every position, retaining data even after power loss.
Industrial Encoders: Incremental & Absolute Component Intelligence
Precision motion feedback for industrial automation and robotics.
What are Industrial Encoders: Incremental & Absolute components?
Encoders provide critical feedback for motion control. Choose between incremental types for relative position and absolute types for instant position data upon power-up. Key specs include resolution (PPR), output signal type (TTL, HTL, SSI), and mechanical mounting interface.
How to Choose Industrial Encoders: Incremental & Absolute Components
Select an encoder based on the control loop requirements and the physical environment of your application.
Incremental vs. Absolute
Use incremental for speed/direction; use absolute when the system must know its exact position immediately after power-up.
Resolution (PPR)
Match the pulses per revolution to your required control precision; higher resolution requires higher bandwidth processing.
Output Signal Type
Ensure compatibility with your PLC or controller inputs (e.g., Open Collector, Push-Pull, Line Driver/RS-422).
Mechanical Interface
Verify shaft type (hollow vs. solid), mounting flange, and IP rating for dust/moisture ingress protection.
Communication Protocol
For absolute encoders, ensure the interface (SSI, BiSS, CANopen, EtherCAT) matches your industrial network.
