Seat position sensors are devices designed to detect and monitor various parameters related to seating arrangements in a vehicle. These sensors are important in determining an occupant's relative position to the steering wheel or dashboard, this ensures safe deployment of the airbag during an accident. CTS develops and customizes a wide range of seating sensors designed for fast response and ensuring occupancy safety. Our Seat Track Position Sensors, Seat Belt Tension Sensors, and Seat Belt Buckle Switches are created to ensure long-term durability and quality without extra cost.

Our seat track position sensor is an environmentally sealed, non-contacting sensor that works in conjunction with Occupant Classification Systems (OCS) and low-risk deployment airbags.
A magneto-resistive (MR) element takes advantage of a material’s tendency to change its electrical resistance with a change in the direction of an externally applied magnetic field. The MR chip works in magnetic saturation, meaning that it does not sense the magnitude but rather the direction of the applied magnetic field. The MR element is protected from magnetic interference, an important feature in automotive applications.
Traditionally, Hall-effect sensing functions by creating a voltage potential proportional to the magnetic field strength. On the other hand, the anisotropic magnetoresistive (AMR) functions by varying the electrical resistance through the device depending on the direction of the magnetic field across the element. Additionally, a typical Hall sensor solution will require multiple Hall-Effect Device (HED) chips along the entire stroke to detect the movement of a magnet. This makes the MR sensor up to 40% more cost-effective since it requires only a single chip to detect the target’s position throughout the whole stroke length.
Seat Adjustment and Memory Settings: Advanced seat sensors enable automatic adjustment of seat positions based on the detected occupant's size and preferences. Memory settings can be programmed to remember individual occupants' preferred seating positions.
