Overview

The LDC1001NHRR is a 16-bit Inductance-to-Digital Converter (LDC) designed for high-resolution short-range sensing of conductive targets. It utilizes inductive sensing technology to measure the position, motion, or composition of a metal target by detecting changes in the eddy currents of a sensor coil. This dual-channel device operates over a wide temperature range of -40degC to 125degC, making it suitable for demanding environments.

Why Choose This Part

The LDC1001NHRR offers sub-micron resolution for displacement sensing and is immune to non-conductive interference such as oil, dirt, and dust. Its 16-bit SPI interface simplifies integration with microcontrollers while supporting high-speed data acquisition. The device is highly reliable for harsh environments due to its wide 3.3V to 5V supply range and high-temperature tolerance.

Applications

Inductive Proximity Sensing
Detecting the presence or distance of metallic objects in industrial automation and safety interlocks.
Rotary and Linear Encoders
High-resolution position sensing for motor shafts or linear actuators using patterned metal targets.
Material Composition Analysis
Distinguishing between different types of conductive metals based on their electromagnetic properties.
Metal Press and Stamp Monitoring
Monitoring the integrity and displacement of metal parts in heavy manufacturing equipment.
Fluid Level Sensing
Non-contact level measurement by tracking a metal float inside a non-conductive tank.
