Magnetic Scale Selection Guidelines for Linear Motors

Magnetic scales based on magnetic-field sensing provide precise positioning for linear motors and other automation equipment. When selecting a magnetic scale, consider the following factors:

1. Measurement range: choose a scale that covers the required travel.

2. Accuracy requirements: select accuracy appropriate to machining or system tolerance (e.g., ±5μm, ±10μm, ±20μm).

3. Resolution: higher resolution improves control precision for linear motors.

4. Linearity: pick products with good linearity to ensure uniform accuracy across the range.

5. Environmental adaptability: consider temperature, humidity, vibration and contamination resistance; choose dustproof/waterproof and anti-interference types as needed.

6. Interface type: ensure output signal type (TTL, HTL, Sin/Cos, etc.) matches your controller.

7. Installation method: select direct-mount or side-mount types based on space and assembly.

Atonm offers MH0, MRR and other series read heads with strong anti-interference and rugged designs suitable for harsh conditions. Evaluate measurement range, accuracy, resolution and environment to choose the right scale for reliable operation.
