November 14, 2024 /SemiMedia/ — Allegro MicroSystems, Inc. recently introduced its new inductive position sensors and a series of micropower magnetic switches and latches. These advanced sensing products lower system costs, extend battery life and offer reliable performance across a variety of automotive, industrial and consumer applications.

Allegro’s new inductive position sensors, the A17802 and A17803, push the boundaries of position sensing, offering a compact and economical alternative to traditional resolvers and encoders used for motor position sensing. These high-resolution sensors with integrated diagnostics perform consistently across a wide temperature range, making them ideal for traction motors in electric vehicles and servo motors in industrial automation and robotics.

The new micropower magnetic switches and latches, APS11753 and APS12753, redefine position sensing with higher sensitivity options for enhanced air gap tolerance, and ultra-low power consumption using 50% less power than our existing micropower products. This makes them perfectly suited for challenging battery-powered applications in medical, consumer and industrial markets.

"We are excited to announce our latest inductive position sensors as we continue to drive innovation in sensing technology,” said Ram Sathappan, Sr. Director, Global Marketing & Applications at Allegro MicroSystems. "Our inductive sensors deliver high accuracy, advanced diagnostics and connectivity options essential for safety-critical traction motors in electric vehicles, while the magnetic switches and latches enable designers to achieve reliable and energy-efficient position sensing in a variety of applications. We’re anticipating a lot of interest in our solutions and look forward to showcasing these innovations at Electronica.”
