Magnetic sensors are not a single brand but a category of devices used across various industries. These sensors are produced by multiple companies worldwide, including leading manufacturers like Honeywell (USA), TE Connectivity (Switzerland), and Allegro MicroSystems (USA). They serve industries such as automotive, industrial automation, consumer electronics, and healthcare. Key products include Hall-effect sensors, magnetoresistive sensors, and reed switches, which are used for position detection, speed measurement, and current sensing. These components are critical in applications ranging from anti-lock braking systems (ABS) in vehicles to industrial motor controls and smart home devices.
