Motion control & sensor interfaces
The Motion & Sensing Series sets itself apart as a key enabler for both the nuclear and space sectors. In nuclear applications, it replaces bulky analog cabling with streamlined digital communication, significantly reducing cable complexity and improving system maintainability. In the space industry, it supports the development of standardized robotics and motion control solutions, enhancing modularity and reusability.
Designed for robust performance in the harshest environments, these components can operate independently or as part of sophisticated robotic and autonomous systems. By enabling these systems to collect vital data and securely transmit it to a control base, the Motion & Sensing Series provides a critical differentiator: reliable, radiation-hardened solutions that promote safer, more efficient operations in both nuclear and space domains.
Functionality
The MAG-POS00002-NP simplifies analog encoder solutions by providing a streamlined method for converting resolver and LVDT signals directly into digital data. This radiation-tolerant converter eliminates the need for complex external circuitry, allowing for easier integration into position sensing systems.
The device reads angular data from a resolver or linear displacement data from an LVDT, delivering precise 16-bit resolution at up to 40,000 samples per second. By handling the entire signal conversion internally, the MAG-POS00002-NP significantly reduces the design effort and complexity typically associated with traditional analog encoder implementations.
