Automotive Sector – Spearheading the Growth of the Magnetic Field Sensors Market
Magnetic field sensor market has a great potential to grow, owing to its properties such as high sensitivity, low power consumption, high switching speed, temperature stability, and so on. Technological advancements in this industry over the years have increased the applications of these magnetic field sensors in various commercial sectors. Today, magnetic field sensors are mainly used in the automotive segment for Anti-Lock Braking Systems (ABS),engine control, steering angle sensing, and force and torque sensing. Apart from these, the magnetic field sensors products are finding applications in the consumer electronics industry in devices such as smart phones, tablets, and laptops, among others.
Hall Effect magnetic field sensors are used in the automotive segment for current sensing, speed detection, and positioning. These sensors are also used to determine the position of crankshafts and camshafts. Micronas, which is a Switzerland based company, is one of the key suppliers of the linear Hall sensors; and delivered more than 2.5 billion Hall sensors to the automotive industry in 2012;these sensors are used for detecting the throttle valve and accelerator position and for exhaust gas recirculation. The magnetoresistive magnetic field sensors are used in engine management, gearbox, transmission systems, vehicle speed, Electronic Throttle Control (ETC),DC motor commutation, Variable Valve Control (VVC), pedal and wiper positioning, automatic headlight adjustment, Electronic Power Steering (EPS) for rotor positioning and torque sensing, and seat positioning.
In the magnetic field sensor market, the automotive segment is expected to hold the major chunk of the market share by 2020,and is estimated to grow at a CAGR of 7.93% from 2014 to 2020. The government is also playing a significant role in the growth of the automotive magnetic field sensor market. For instance, environmental regulations in Europe tend to limit the pollution caused by road vehicles. This will boost the growth of the hybrid and electric cars, which use magnetic field sensors for current sensing and motor drive controlling applications. Although, the safety regulations have provided significant opportunities for the magnetic sensor growth, the environmental regulations have been a strong driver for the growth of the automotive magnetic sensor market worldwide. These steps from the government have stimulated the growth of the vehicle security industry with magnetic field sensor applications such as antilock braking system and the central locking system. The‘Powertrain’ in which the magnetic sensors are used is acting as an emerging automotive application for the magnetic field sensor market in the Asia-Pacific region and is expected to show a promising growth in the coming future.
Significant up gradation and development of new magnetic field sensors for the automotive market have been the main strategies followed by the key players such as Allegro MicroSystems Inc. (U.S.), Infineon (Germany), Asahi Kasei Micro devices Corporation (Japan), Austria Microsystems AG (Germany), and Honeywell International (U.S.).
