Customized sensor VS-399

Customized seat pressure sensor VS-399 is a new sensor designed and developed recently by Vmanx RD team. It’s a kind of membrane type contact sensor. The contacts of sensor evenly distribute on the stress-bearing surface of seat, will generate a trigger signal when the external force presses on the seat. It can be applied to the seat occupant perception system. For example, with this device, pressure sensor can detect if anybody sits or not, and the airbag won’t open if nobody. It can also design the dimension of sensors and sensitivity of contacts as the shape and hardness of seats.
