Which Is More Accurate: Magnetic Scale or Optical Grating Scale?

Both magnetic scales and optical grating scales are used to measure length and angle in industry and research. Many wonder which offers higher accuracy; the answer depends on the specific application and environment.

Magnetic scales measure using magnetic patterns and can achieve micron-level accuracy while maintaining stability in harsh environments. They resist oil, liquids, dust, and vibration, making them well suited for industrial settings.

Optical grating scales use optical principles and can also reach micron-level or higher accuracy, often offering non-contact measurement advantages that reduce errors from mechanical contact.

Therefore, both technologies can achieve high precision; the better choice depends on environment and measurement requirements. Consider material, installation, and operating conditions when selecting between them.

Atonm magnetic scale read heads use imported, wear-resistant shielded cables and robust anti-interference hardware/software designs for strong noise immunity. They satisfy high-precision displacement measurement needs and withstand oil, liquids, dust, and vibration. The product is compact for easy installation and currently available in two series: MRR and MH0.
