Speed and Position Sensors

The sensors are measuring devices that monitor speed and position of rotating objects in order to:

  • Set ignition timing
  • Determine engine speed and provide RPM signal
  • Prevent the brakes from locking
  • Calculate the transmission’s actual gear ratio
  • Establish injector synchronization and coil firing sequence
  • Modify engine functions such as air/fuel ratio and transmission shift points
  • Indirectly monitor tire pressure

Our speed and position sensors use various technologies:

  • Giant Magnetic Resistance
  • Hall Effect
  • Variable Reluctance

Product Range

  • SMP makes speed and position sensors in a broad range of materials to provide compatibility with different media (e.g. engine oil, transmission fluid, water, air, etc.) and mounting port materials
  • Different mounting options available (e.g. threaded connection, flange mount, push-fit etc.)
  • Different connector types, both on-harness and integrated with sensor body, different electrical contact materials – can be adapted to any customer needs
  • Available in a range of operating temperatures
  • Different output types available (analog, PWM, etc.)
  • Direction detection capability
