The Magnescale SJ700A is a cost-effective, high-performance linear magnetic scale designed for digital readout (DRO) systems. Built with Magnescale’s proven magnetic sensing technology, the SJ700A offers excellent resistance to workshop conditions, making it ideal for retrofitting machine tools and integrating into new CNC systems. Its semi-modular design and integrated detector simplify installation and ensure long-term reliability.

The SJ700A is engineered to perform in harsh industrial settings. Its magnetic detection system is inherently resistant to oil, coolant, dust, and vibration—common challenges in machining environments. With a resolution of 5 μm and measuring lengths ranging from 150 mm to 1,600 mm, the SJ700A delivers consistent, accurate feedback for a wide range of machine tool applications.

Key features

Semi-Modular Design for Easy Integration

This scale features a semi-modular structure with the detector built directly into the scale body. The relative positions of the scale and head are pre-aligned and secured using a slide holder, reducing installation complexity. The SJ700A can be connected directly to Magnescale counters such as the LG20 or LH70 series, enabling fast setup and seamless operation.

Thermal Stability and Mechanical Compatibility

The SJ700A is designed with the same coefficient of thermal expansion as machine tools, ensuring measurement stability even under fluctuating temperatures. This makes it particularly suitable for precision machining environments where thermal drift can affect accuracy.

Ideal for Retrofitting and OEM Applications

Whether you’re upgrading an older machine or designing a new system, the SJ700A offers a robust, economical solution for linear position feedback. Its rugged construction and straightforward installation process make it a favourite among machine builders and maintenance engineers alike.

Applications

  • CNC lathes and milling machines
  • Manual machine tool retrofits
  • Digital readout (DRO) systems
  • Metal cutting and forming equipment
  • General-purpose industrial automation
