Daisy-Chaining Magnetic Sensors for Multi-Axis Control

Simplify wiring and boost efficiency with AKP18

In multi-axis automation, wiring complexity can slow down development and increase failure risks. This often requires the simultaneous tracking of multiple movements - linear, rotary, or both - which traditionally involves complex wiring and higher installation efforts.
The daisy-chain capability of BOGEN’s AKP18 absolute magnetic sensor offers a smarter solution.

Why daisy-chain?
• Up to 7 sensors can be connected in series (via wire-to-board connector)
• Fewer cables, less clutter: One main line instead of multiple individual sensor lines
• Simplified integration into motion control systems, especially in compact or modular machines

How it improves multi-axis systems
• Ideal for robotic arms, gantry systems, and coordinated axis platforms
• Allows synchronized, absolute position feedback across multiple axes
• Reduces electrical noise and potential interference from long wiring runs

Technical highlights
• Daisy-chain setup using Molex Pico-Clasp 12-pin & Amphenol FCI connectors
• Supports BiSS-C protocol over standard RS422 differential lines
• Enables clean wiring architecture for dependable sensor-to-sensor communication.

Use Case: Multi-axis robotic platform
In a six-axis robotic arm, individual joints are equipped with AKP18 sensors. Instead of separate connections for each encoder, the sensors are daisy-chained along the arm using recommended Molex Pico-Clasp and Amphenol FCI connectors.

Result:
• 60% reduction in wiring effort
• Streamlined control integration via BISS-C
• Faster commissioning and enhanced system reliability

→ More efficient motion control with less engineering effort
