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

Shielding
For optimum performance:
• Ensure 100% shielding
• Ground the mounting brackets
• Ensure continuity of all shields
• Maximise the distance between the encoder and motor cables
• Provide appropriate strain relief at the readhead
