Key Technical Highlights
1. Industrial-Grade RS485 Bus
Differential signaling provides elite noise immunity against EMI from machinery, supporting long-distance multi-node control (100m+).
2. Monster 130kg Torque & 4S Efficiency
Optimized for 16.8V HV integration, producing 1805 oz-in of torque to manage massive mechanical joints.
3. Magnetic Precision & Brushless Endurance
12-bit magnetic encoder ensures zero-drift accuracy and near-infinite life across millions of high-torque cycles.
4. Full CNC Armour & Socket Interface
The 61mm full CNC aluminum case acts as a heatsink, with a professional socket interface for easy maintenance.
Frequently Asked Questions
Differential signaling is much more robust against data corruption in noisy industrial sites with long cables.
Yes, supports multi-node addressing via unique IDs through a single pair of signal wires.
Selecting the XQ-RS9100D for Long-Cable Installations
On the XQ-RS9100D the differential RS485 pair is usually the deciding feature rather than torque alone, because it is what keeps commands intact on the long, electrically noisy runs found around machinery. One pair of signal wires carries multi-node addressing through unique IDs across 100 m+ of cable, so several joints can hang off a single controller without star wiring. Output follows the pack: 90 kg.cm at 8.4 V (2S), 110 kg.cm at 12.0 V (3S) and 130 kg.cm at 16.8 V (4S), with response tightening from 0.20 s to 0.12 s and peak torque reaching 1805 oz-in. Where a joint has to move a large mass quickly, 4S is the setting to specify. The 12-bit contactless magnetic encoder gives zero-drift position feedback across millions of high-torque cycles, and the 61.0 x 30 x 60.4 mm, 190 g housing doubles its full CNC aluminium case as a heatsink. The same 130 kg.cm platform is also offered with a MODBUS-RTU interface, described on the XQ-RS9100MB MODBUS-RTU actuator page.
