On 15 November, Allegro MicroSystems, a provider of power and sensing solutions for motion control and energy-efficient systems, announced a new inductive position sensor and a range of micropower magnetic switches and latches. These advanced sensing products reduce system costs, extend battery life and provide reliable performance in a variety of automotive, industrial and consumer applications.

The new micropower magnetic switches and latches, APS11753 and APS12753, redefine position sensing with higher sensitivity options for enhanced air-gap tolerance and extremely low power consumption, up to 50 per cent less than existing micropower products. This makes them ideally suited 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 global marketing and applications at Allegro MicroSystems. Our inductive sensors provide high accuracy, advanced diagnostics and connectivity options that are critical for safety-critical traction motors in electric vehicles, while magnetic switches and latches enable designers to achieve reliable and energy-efficient position sensing in a variety of applications. We expect great 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):

Accurate non-contact angular and motor position sensing: enables dynamic speed and torque control for smoother motion, reduced vibration and energy savings.

Wide temperature range: Consistent performance and stability at temperature extremes, 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 them ideal for portable and wireless devices.

Design flexibility: A wide range of magnetic sensitivity options are available, providing design flexibility to meet a range of application requirements from stray field rejection 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, resulting in greater air gap variations and total cost savings

Allegro's latest solutions underscore its commitment to sensing innovation throughout 2024. Earlier this year, Allegro introduced the industry's highest bandwidth current sensors (ACS37030 and ACS37032), designed to enable fast response and minimal power loss in high power density silicon carbide (SiC) and gallium nitride (GaN) systems. These solutions are used in a wide range of applications such as electric vehicles, clean energy equipment, and data centres.Allegro has also introduced shunt replacement current sensors (ACS37220 and ACS37041), which reduce energy loss and component count compared to traditional shunt-based solutions.

Additionally, Allegro expanded its portfolio with new XtremeSense™ TMR sensors (CT455 and CT456), which save space and cost while improving energy efficiency.
