SPC-RB-18 20mm Hollow Shaft Conductive Slip Ring 18 Circuits 5A CAN Bus for Collaborative Robot Joint

SPC-RB-18 20mm Hollow Shaft Conductive Slip Ring 18 Circuits 5A CAN Bus for Collaborative Robot Joint

The SPC-RB-18 conductive slip ring is built for collaborative robot joints that must rotate continuously without cable wrap. Eighteen circuits at 5A include six shielded pairs for CAN bus and encoder feedback, and the 20mm hollow shaft lets tooling cables pass through the joint center.

Key Advantages

• Six shielded pairs dedicated to CAN bus and encoder signals keep noise below 5 mΩ.
• 18 circuits at 5A cover joint motor, brake, encoder and IO in a 72mm body.
• 20mm hollow shaft routes tooling cables and air lines through the joint center.
• Gold-gold contacts maintain signal integrity over 15 million joint revolutions.
• Compact 0.6kg mass keeps collaborative robot arm inertia within safety limits.
