LinkCompact Incremental Linear Encoder for CNC Machine Tools
The Magnescale SR24 is a compact incremental linear encoder with an enclosed design, developed for high‑accuracy position feedback in CNC machine tools and precision equipment.
Featuring a slim, low‑profile construction, it is ideal for installations where space is limited, while its magnetic, non‑contact sensing principle ensures reliable performance even in harsh industrial environments. The SR24 outputs A/B quadrature signals with a reference point (EIA‑422), making it compatible with a wide range of motion control systems.
Key features
- Slim, space‑saving design – Optimised for installation in narrow machine spaces
- Incremental high‑speed feedback – A/B quadrature output enables precise motion control
- Reliable in harsh environments – Magnetic sensing allows operation in coolant, oil and contamination
- Enclosed construction – Protects internal components for consistent performance
- Flexible reference options – Centre, multi‑point or user‑defined reference positions


How it works
The SR24 uses a non‑contact magnetic measurement system:
- Sensor reads position along an enclosed scale
- Outputs A/B quadrature signals plus reference point
- Signal is used by the controller to track position and movement
This results in:
- High‑speed response for dynamic motion
- Stable performance in real machining environments
- Simple integration with standard control systems
Typical applications
- CNC machining centres
- Milling and turning machines
- Compact linear axes
- Automation and positioning systems
- Applications requiring space‑saving incremental feedback
Compatible systems
- The SR24 is designed for integration with:
- • Motion controllers supporting A/B quadrature input
- • CNC systems using incremental encoder feedback
Why choose SR24?
- Ideal for compact machine designs with limited space
- Provides cost‑effective incremental feedback
- Reliable operation in real industrial environments
- Easy integration with standard control systems
