Fanuc A860-0203-T001 Handwheel encoder – CNC spare part
Precise manual control for CNC machines
The Fanuc A860-0203-T001 is an original handwheel encoder for precise manual control of CNC axes. It is frequently used for setup, measurement, positioning, and test runs. Its reliable signal transmission enables sensitive movements of the X, Y, or Z axes, thus providing greater control during setup and correction.
The encoder is compatible with numerous Fanuc CNC controls, including the 0i, 16i, 18i, 21i, 30i, and 31i series. It can be installed in milling machines, lathes, and machining centers from various manufacturers such as Fanuc, DMG Mori, Haas, Mazak, and Hurco. Ideal as a replacement part or for retrofit applications.
Characteristics:
- Original Fanuc handwheel encoder (MPG / Pulse Generator)
- Fine axis positioning during setup and homing
- Compatible with many Fanuc controllers
- Robust and durable for continuous industrial use
- Easy installation and reliable signal accuracy
- Ideal as a spare part or for service and maintenance
Suitable for:
- CNC milling machines
- lathes
- Machining centers with Fanuc control
- Machine service, conversion or modernization

FAQ
Handwheels for machine tools
What are handwheels used for on machine tools?
Handwheels are used for the manual control of machine axes, especially during setup, positioning, and maintenance work. They enable precise and controlled axis movement.
When should a handwheel be replaced?
Replacement is advisable if the handwheel provides inaccurate signals, jerks, has play, is damaged, or executes axis movements with a delay. It should also be replaced if it fails during setup or axis referencing.
Can I install any handwheel in any CNC machine?
No. It must be compatible with the controller (e.g., Fanuc, Siemens, Heidenhain) and the connection (pin assignment, voltage, signal type). Mechanical dimensions such as diameter and mounting must also be correct.
Which machine manufacturers use such handwheels?
Handwheels are used in machines from Fanuc, DMG Mori, Mazak, Haas, Hurco, Okuma, Siemens, Heidenhain and many other machine tools.
Are there differences between mechanical and electronic handwheels?
Yes. Mechanical handwheels are used to directly move an axis, while electronic handwheel encoders (MPG) send signals to the controller, which then moves the axes.
What is a handwheel encoder (MPG)?
An MPG (Manual Pulse Generator) is an electronic handwheel that sends pulses to the CNC controller. This allows the axis to be moved precisely and in a controlled manner in small increments.
How do I identify the correct replacement type?
Important information includes the model number, control type, connections, pulse resolution (e.g., 25 or 100 PPR), and form factor. Nameplates or old part numbers can help with matching.
