LDC0851 Event Counting Reference Design


Design files


An inductive sensing (LDC)-based event counting design providing a robust and low-cost interface for speed measurement and event counting applications.  The solution doesn't require magnets and reliably operates in environments with dirt, moisture or oil that usually pose challenges for alternate sensing technologies.

  • Highly reliable, contactless event counter using LDC technology
  • No calibration required
  • Measurement of >300 events / second
  • No permanent magnets required; operates effectively even with magnetic or electrical enviromental interference
