Absolute magnetic linear encoders are connected to various connection options such as external drives, motion control cards, PLCs, etc. via ultra-flexible, highly sensitive cables. Due to the strong and stable design of the magnetic scale encoder and cable, good electromagnetic compatibility (EMC) of the absolute encoder system is ensured.
Features
- The absolute magnetic linear encoder has a true dual-channel feedback system, which is suitable for high-speed, multi-motor pulley operation scenarios.
- The magnetic scale encoding cycle is the same, and the length is 126mm.
- During the magnetic scale crossing process, it can automatically switch between zero and absolute position information, and keep communication smooth. The detection blind area is very small.
- The absolute magnetic strip encoder supports multiple communication protocols such as BISS-C, SSI, Tamagawa, RS-485, etc.
- It adopts a widened appearance structure design and supports multiple specifications of magnetic scales with widths of 12mm, 15mm and 20mm.
- The absolute magnetic linear encoder adopts IP67 grade epoxy resin potting process.

Tips: How does an absolute magnetic linear encoder work?
An absolute magnetic linear encoder utilizes a scale with magnetic field patterns, a sensor head, and processing electronics to determine position accurately. The scale contains magnetic regions representing digital position information. As the sensor head moves along the scale, it detects the magnetic field variations. Each unique magnetic pattern corresponds to a specific position. The sensor head captures these patterns and converts them into digital signals. Processing electronics then interpret these signals to determine the precise position along the linear path. Unlike incremental encoders, which require a reference point to determine absolute position, absolute magnetic linear encoders provide position information without the need for a homing or initialization sequence. This inherent absolute positioning capability makes them ideal for applications requiring high precision and reliability, such as in industrial automation, CNC machines, and robotics.
