Position sensing technologies are essential to modern motion control systems, yet most non-contact sensing solutions, including Hall, AMR, GMR, TMR, inductive, optical, and resolver-based sensors, are limited to measuring a single 360-degree rotation.
The ADMT4000 breaks through this limitation as the world’s first and only single-chip absolute multiturn position sensor, delivering accurate position measurements across 46 full rotations, or 16,500 degrees, with angular accuracy of ±0.25°. By leveraging a unique Shape Anisotropy effect and a patented nanowire-based GMR structure, the sensor retains rotational position information without requiring power, enabling true absolute multiturn sensing in a compact, contactless design.
Join this webinar, where our expert will explore the technology behind the ADMT4000 and how its ability to track multiple rotations and angular movement without power is transforming the design of both linear and rotary actuators.
Attendees will gain insight into:
- How ADI’s unique multiturn technology works
- ADMT4000 overview and reduced form factor insight
- Advantage of the technology in robotics
- humanoids and general-purpose industrial automation equipment
