An electronic device called a Hall effect sensor is made to detect the Hall effect and turn the results into data that can be used to switch a circuit on and off, measure a changing magnetic field, be processed by an integrated computer, or be shown on an interface.
The Hall Effect is the result of a conductor or semiconductor being introduced perpendicular to a magnetic field and producing a voltage that can be measured. The Hall effect can be used to detect the presence of a current on a magnetic field as well as to assess the density of current carriers, their freedom of movement, or mobility.
Researchers, manufacturing facilities, commercial enterprises, the auto industry, and more can all benefit from the Hall effect. When used for production, inspection, and testing, hall sensors may monitor voltage, current, and magnetic fields. These are a few of the most frequent uses for the Hall effect.
The Global EV Hall effect sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Allegro introduces a coreless, Hall-effect current sensor for use in industrial and electric vehicle applications. A novel, coreless Hall-effect current sensor for demanding automotive and industrial applications has been introduced by Allegro MicroSystems, Inc., a developer of sensing and power solutions for motion control and energy-efficient systems.
It offers greater sensitivity and accuracy, more fault detection options, and user-programmability. The ACS37610 sensor from Allegro joins the ACS37612 as the first family of truly coreless Hall sensing products in the industry.
It is designed to measure currents flowing through a busbar or PCB trace with an average accuracy of 1% without the use of an external concentrator or U-shaped magnetic shield.
System designers can achieve increased efficiency and improved power density while lowering system complexity, BOM, cost, footprint, and weight thanks to these cutting-edge innovations.
Allegro was the first company to commercialise coreless, differential Hall-effect current sensing technology, and their new ACS37610 IC allows its customers to precisely measure hundreds or thousands of amps in an easy and cost-effective manner.
Without the requirement for a shield, which is necessary in competing technologies and slows reaction and introduces non-linearity error into the system, their differential Hall-based sensors offer exceptional immunity to errant magnetic fields.
NXP Semiconductors created the KMA220 Hall effect sensor for use in motor control applications for electric vehicles (EVs). It is a very accurate, low-power sensor that provides precise readings of both linear position and angle.
