Tension and Presence Sensing Series - Hall

Tension-Presence-Seat-Belt-Buckle-Sensor
Roll Over to Zoom

The seat belt presence sensor detects whether the seat belt buckle is latched or unlatched. The tension sensor detects the tension of the seatbelt. This sensing system helps determine the optimum airbag deployment. It is also used as an input to the electronic park brake and the unbuckled warning system. 

 

Applications:

  • Vehicle occupant safety systems

  • Robust construction makes this sensor well suited to harsh environments

  • Non-contact, Reed and Hall Effect technology

  • Magnetically operated position sensor
  • Integrated in spring loaded seat belt buckle
  • Dual output for 1) presence and 2) tension
    1. Two logic output states (100 &400 Ohm)
    2. Ratiometric voltage output (belt tension)
  • Operates when the thorn in the seat belt buckle moves from an unlatched to a latched position
  • Choice of cable length and clips
  • Choice of connector and terminals
  • Ability to customize sensor output to customer needs
