Frequently asked questions about ROD426-2000:

Is this an incremental or absolute model?
It is an incremental rotary encoder from the HEIDENHAIN ROD series. It provides A and B tracks with a reference function for homing and direction detection.

How many counts per revolution does it provide?
This variant is rated at 2000 increments per revolution. Effective resolution at the control can be higher when interpolation is applied by the drive or CNC.

What should be checked before using it as a drop-in replacement?
Verify the ID 376 846-05 against your machine list to confirm shaft diameter, flange style, connector or cable execution and the required electrical interface and pinout.

Where is it commonly installed on machine tools?
It is used on feed axes, rotary axes and auxiliary drives where reliable incremental feedback is needed for precise positioning and stable speed control.

Do you support repair or exchange programs?
Yes, depending on the unit condition and availability, repair service and exchange service can be proposed to help reduce downtime and manage spare inventory.
