A seat track position sensor uses the Hall switch technology to measure the position input for dual-stage airbags. Unlike seatbelt buckle sensor ICs, seat position sensor ICs typically use a vane interrupt sensing style to determine which seat area is located along the seat line. A seat track position sensor includes a magnet on either side of the seat track and a unipolar Hall-effect switch. Seat rail location sensors detect the front seat position and provide information essential for airbag control.
Several sensor ICs can be employed to determine different positions along the seat line, which can subsequently be used to determine the driver's relative position on the steering wheel or dashboard by using the airbag deployment controller
The purpose fulfilled by the seat track position sensor is that it detects the front and back positions of the driver seat. The seat track position sensor converts the seat position into an electrical signal and transmits it to the SAS control module. The seat track position sensor consists of a Hall element (semi-conductor) and a magnet. The sensor converts the effect of the magnetic flux (produced by the magnet) on the Hall element into an electrical signal. The seat track position sensor is installed on the driver-side seat rail.
If the driver’s seat is slid forward, the seat track position sensor separates from the metal plate installed to the seat slider. When this occurs, the magnetic flux of the sensor changes and that change is transmitted as an electrical signal to the SAS control module. The SAS control module receives this signal and determines that the driver’s seat has been moved to a forward position.
Increase in demand for driver safety and a rise in purchase of automobiles are boosting the global seat track position sensor market. However, use of these sensors may result in faulty systems due to their automation. This, in turn, restrains the market.
In spite of these challenges, advancements in the field of sensors and sensing components are expected to provide immense opportunities to the global seat track position sensor market during the forecast period.
Demand for these sensors is increasing at a rapid pace due to various benefits offered by seat track position sensors, such as flexible switch points and high gap tolerance, multiple applications, excellent field performance on several OEM platforms, and low-cost designs.
Adoption of seat tract position sensors is rising considerably owing to their high accuracy and robust construction. These factors are anticipated to fuel the global seat track position sensor market in the near future.
Furthermore, increasing demand for security in aerospace and defense sectors is also a key factor that is estimated to boost the market. Rise in manufacture of aircraft is also a major factor fueling the market for seat track position sensors.
In terms of region, the global seat track position sensor market can be divided into North America, Europe, Asia Pacific, Latin America, and Middle East & Africa
North America is expected to lead the global market for seat track position sensors between 2021 and 2031, due to the presence of a large number of automobile manufacturers and ongoing technological innovations in the region.
Europe is expected to witness an increase in the demand for advanced automotive technologies in the near future. This, in turn, is likely to drive the market for seat track position sensors in the region during the forecast period. This is also expected to offer lucrative opportunities to global automotive manufacturers to expand their presence in the region.
