This absolute magnetic linear encoder can provide accurate absolute physical position information without phase search 350ms after power-on. It is very stable and reliable due to its non-contact, wear-free measurement principle and built-in safety algorithm. The magnetic scale comprises an incremental code channel composed of a 2mm pole pitch and an absolute code channel composed of binary code. Therefore, during installation and use, the direction between the encoder and the encoder needs to be matched.
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 512mm.
- 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 to choose an absolute magnetic linear encoder?
Choosing an absolute magnetic linear encoder involves considering several key factors. First, determine the required resolution and accuracy for your application. Evaluate the encoder's resolution, typically specified in micrometers or nanometers per unit of measurement. Next, assess the required length of travel and ensure the encoder can accommodate it. Consider the environmental conditions such as temperature, humidity, and exposure to contaminants, and choose an encoder with appropriate IP (Ingress Protection) ratings. Additionally, assess the speed and acceleration requirements of your application and select an encoder with suitable frequency response and dynamic performance. Consider the installation space and mounting options, ensuring compatibility with your system. Lastly, evaluate the cost and reliability of different encoder options, balancing performance requirements with budget constraints.
