Texas Instruments unveiled what it asserts is the industry’s first inductance-to-digital converter (LDC), a data converter category that uses coils and springs as inductive sensors. This contactless sensing technology can be used to measure the position, motion, or composition of a metal or conductive target, as well as detect the compression, extension or twist of a spring. LDC technology is positioned to enable sub-micron resolution in position-sensing applications with 16-bit resonance impedance and 24-bit inductance values. Contactless sensing is immune to nonconductive contaminants, such as oil, dirt and dust, which can shorten equipment life, and the technology allows the sensor to be located remotely from the electronics, where PCBs cannot be placed.
