The new micropower magnetic switches and latches, the APS11753 and APS12753, redefine position sensing with higher sensitivity options, enhanced air gap tolerance, and extremely low power consumption, 50% less than existing micropower products. This makes them ideal for challenging battery-powered applications in the medical, consumer and industrial markets.
“We are pleased to announce our latest inductive position sensors as we continue to drive innovation in sensing technology,” said Ram Sathappan, Senior Director of Worldwide Marketing and Applications at Allegro MicroSystems. “Our inductive sensors offer high accuracy, advanced diagnostics, and connectivity options that are essential for safety-critical traction motors in electric vehicles, while magnetic switches and latches enable designers to implement reliable and energy-efficient position sensing in a wide range of applications. We anticipate significant interest in our solutions and look forward to showcasing these innovations at Electronica.”
Key features and benefits of the new inductive position sensors (A17802 and A17803):
Precise, contactless angle and motor position sensing: Enables dynamic speed and torque control for smoother motion, reduced vibration and energy savings.
Wide temperature range: Maintains consistent performance and stability in extreme temperatures, ensuring reliability in harsh conditions.
Integrated digital compensation and programmable linearity: Improves accuracy and resolution while providing design flexibility.
Key features and benefits of the new micropower magnetic switches and latches (APS11753 and APS12753):
Ultra-low power consumption: Extends battery life, making it ideal for portable and wireless devices.
Design Flexibility: A wide range of magnetic sensitivity options are available to provide design flexibility for a range of application needs, from stray field suppression to high sensitivity low magnetic field use cases.
Lower total solution cost: Higher magnetic sensitivity options compensate for mechanical misalignment and magnetic field strength variations, allowing for greater air gap variation and overall cost savings
Allegro's latest solutions demonstrate its commitment to sensing innovation throughout 2024. Earlier this year, Allegro launched the industry's highest bandwidth current sensors (ACS37030 and ACS37032), designed to achieve fast response and minimal power loss in high power density silicon carbide (SiC) and gallium nitride (GaN) systems. These solutions are widely used in electric vehicles, clean energy equipment, and data centers. Allegro also launched shunt replacement current sensors (ACS37220 and ACS37041), which can reduce energy loss and component count compared to traditional shunt-based solutions.
Additionally, Allegro has expanded its portfolio with new XtremeSense™ TMR sensors (CT455 and CT456), which improve energy efficiency while saving space and cost.
