Hollow-shaft magnetic encoders represent a structural variant of magnetic encoders, offering flexible positioning of the magnet ring and sensing elements to address position sensing needs in space-constrained environments. When paired with dual-track magnet rings, they enable absolute high-precision positioning detection.
Core Application Scenarios of Hollow-Shaft Magnetic Encoders:
- Robotic Joints & Collaborative Robots
- Servo Motors for Industrial Automation
- Medical Imaging Equipment
- Renewable Energy Systems
- Electric Vehicles & Mobility
Hollow-shaft magnetic encoders redefine motion control in space-constrained, harsh, or safety-critical applications – merging reliability with revolutionary integration flexibility. Contact OTV Sensing for your custom hollow-encoder solutions.
