Servo Encoder Slip Rings
- No Error Code: Shields signals from servo motor noise.
- Fits All Protocols: Works with Absolute (EnDat, BiSS-C, SSI) and Incremental systems.
- Smooth Rotation: Low resistance drop using Gold-to-Gold contacts.
- Flexible Choice: Easy to combine with air/water joints or power lines.
Works Great With Major Servo Brands
How JARCH Helps Stop Servo Machine Errors
1. Metal Shielding (Blocks Noise)
Problem: Motor power noise ruins encoder signals, causing alarm codes on the servo drive.
JARCH Fix: We build metal walls inside to separate power wires from signal wires, plus extra shielding wires.
2. Gold Contacts (No Data Loss)
Problem: Poor ring contacts lose signal bits while rotating, making the motor lose position.
JARCH Fix: We use real gold contact technology so the electrical connection stays stable during 360° turning.
3. Safe Wire Design (Clear Waves)
Problem: Wrong wire setup changes signal shapes and slows down encoder speed.
JARCH Fix: Specially designed wire pairs keep signal waves clean for high-speed transmission.
