This encoder extension cable is designed to interface with the motor encoder of Assa Abloy sliding door operators (SL500, SL510, SL520, SL521). It provides additional length between the encoder unit on the motor and the main control board, allowing more flexible routing or relocation of the control electronics without replacing the entire motor wiring harness.
Key Features & Benefits
Maintains signal integrity between encoder and controller, ensuring accurate speed / position feedback
Compatible with the SL-series sliding door operator range
Designed to match existing connector types used by Assa Abloy systems
Durable insulation and shielding to resist interference in automatic door environments
Helps simplify retrofits or upgrade work where extra cable slack is needed
Typical Use Cases
Replacement of damaged encoder cable without replacing the motor
Extending cabling when relocating control electronics
Repair or refurbishment work in sliding door installations
Important Considerations
Ensure pinout and connector type matches the original encoder cable
Confirm length and gauge meet signal and voltage drop requirements
Maintain shielding continuity to preserve encoder signal integrity
Avoid tight bends, sharp edges or proximity to high-current power cables
