New Car Seat Sensor VS-105

Vmanx Special Car Seat Sensor VS-105 is the newest safety sensor introduced by Dongguan Zhongman Industrial Company Limited (VMANX). Its sensibility is much higher than that of other sensors available in the market. VS-105 is a kind of membrane type contact sensor and comprises all the environment friendly features.


Major Parameters of VS-105:

A. Electrical Properties

  • Working voltage:≤50VDC
  • Working current:≤100mA
  • Contact resistance:0.5~100Ω
  • Insulation resistance:≥100MΩ (100VDC)
  • Substrate material withstand voltage:2kDVC
  • Rebound time:≤6ms
  • Loop resistance:≤100Ω
  • Insulation ink pressure:100VDC

B. Mechanical properties

  • Button life:≥1 million times
  • Closed displacement:0.25~0.35mm
  • Health standard of force:100~300g
  • Lead wire anti-curvature:circuit won’t break with d = 10mm steel rod pressuring and rolling 80 times constantly

C. Environmental Performance

  • Working temperature: -20 ℃ ~ + 70 ℃
  • Storage temperature: -40 ℃ ~ + 85 ℃; Humidity 85% ± 5%



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 bus, car or other vehicle’s seat occupant perception system, such as safety belt reminder (SBR), taxi automatic message accounting system, airbag’s sensor, condition that the driver leaves seat.


For example, with this device, occupancy 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 car seat.
