A Revolution in Sensing

Inductive sensing is a contactless, magnet-free sensing technology that can measure the position, motion, or composition of a metal or conductive target as well as detect the compression, extension, or twist of a spring.

The LDC1000 enables inductive sensing, by utilizing coils and springs as inductive sensors to deliver better performance, better reliability, and greater flexibility than existing sensing solutions – at lower system cost and power.

Key advantages of LDC technology

  • Higher resolution: Enables sub-micron resolution in position-sensing applications with 16-bit resonance impedance and 24-bit inductance values
  • Better reliability: Offers contactless sensing that is immune to nonconductive contaminants such as dirt and dust
  • Greater flexibility: Allows the sensor to be located remotely from the electronics, where PCBs cannot be placed
  • Lower system cost: Uses low-cost sensors and targets – no magnets required
  • Limitless possibilities: Supports pressed foil or conductive ink targets, offering endless opportunities for creative and innovative system design
  • Lower system power: Consumes less than 8.5 mW during standard operation and less than
    1.25 mW in standby mode
