ATOM linear encoder system
For FPC variants
Ensure that the FPC cable being used has the following specications:
• 16core
• Conductor pitch 0.5mm
• Minimum exposed conductor strip length 1.5mm
• Maximum exposed conductor strip length 2.5mm (to ensure isolation from the body)
Contact your local Renishaw representative for more information regarding FPC design requirements.
