The Sensors Expo and Conference 2019, held in San Jose, California, from June 25-27, 2019, was the launching pad for the latest giant magnetoresistance (GMR) wheel speed sensor integrated circuits from Allegro MicroSystems.
Headquartered in Manchester, New Hampshire, Allegro is a provider of power and sensing solutions for motion control and energy-efficient systems. At the Expo, the company offered an interactive demonstration of the new devices, noting that they are an ideal fit for advanced braking systems.
In a press release, the company offered the following selling points:
- Allegro’s patented GMR technology is capable of sensing in both parallel and perpendicular orientations.
- The new devices provide user-friendly, two-wire solutions for applications where information on speed (A19250) or speed and direction (A19350) is required.
- Industry-leading signal processing algorithms allow the ICs to provide the same orientation as Hall effect for drop-in solutions, while also providing the sensitivity advantage of a larger total effective air gap and improved jitter.
Other technologies highlighted by Allegro at the Expo included coreless current sensors for electrified vehicles, smart power monitoring for IoT, vertical Hall technology for intelligent motion and automotive chipsets for functional safety.
