Rotary Torque Sensor_renewal

Maintaining stable measurements under high-speed, repetitive rotational conditions is no simple task.

At AL.Robot, we prioritize the structural consistency and response repeatability that generate accurate torque values.
By transmitting both power and signals wirelessly—without slip rings—we achieve stable output even within rotating components.
The signals we’ve engineered deliver consistent data, even inside continuously rotating systems.

Key Features

AL.Robot’s rotary torque sensor combines wireless power and signal transmission to deliver both precision and durability in high-speed rotational environments.

With a slip ring-free design and high-rigidity structure, it can be reliably integrated into a wide range of industrial equipment.

Reliable Wireless Design Without Slip Rings

Power and data are transmitted wirelessly via a non-contact method, ensuring structural reliability.
This eliminates the wear and noise issues common in traditional slip ring designs, maintaining stable operation even at high rotational speeds.

Power transmission efficiency: up to 90%
Wireless communication speed: up to 1 Mbps
Maintenance-free integrated wireless design

Supports Rotation Speeds up to 10,000 RPM

Stable performance is ensured even in environments with speeds up to 10,000 RPM.
The low-inertia, high-stiffness structure minimizes vibration and interference, enabling highly reliable measurement.
