What are TI's Inductive and Capacitive Sensors?

2025-01-18

Introduction

In the rapidly evolving landscape of industrial automation and precision control, sensors play a pivotal role. Among the various types of sensors, inductive and capacitive sensors stand out for their reliability and versatility. Texas Instruments (TI) offers a comprehensive portfolio of inductive and capacitive sensors, which are widely used in a variety of applications. This article will explore the fundamentals of TI's inductive and capacitive sensors, their applications, and how they are integrated into modern industrial systems, with a special focus on the DAIDISIKE Light Grid Factory.

 Inductive Sensors

1.1 Theory of Operation

Inductive sensors work on the principle of electromagnetic induction. They generate an AC magnetic field which induces eddy currents in a conductive target. These eddy currents, in turn, create a magnetic field that opposes the original field, reducing the inductance of the sensor coil. The change in inductance is detected and converted into a digital signal. TI's inductive sensors, such as the LDC0851, are highly sensitive and can detect even the slightest changes in inductance, making them ideal for applications requiring high precision and reliability.

- Metal Proximity Detection: Inductive sensors are commonly used to detect the presence of metal objects. They are widely used in manufacturing lines to detect the position of metal parts, ensuring precise assembly and quality control.

- Incremental Encoders: These sensors are used to measure the rotation of shafts in motors, providing feedback for precise control. They are essential in applications such as robotics and CNC machines.

- Touch Buttons: Inductive touch buttons offer a non-contact, wear-free alternative to traditional mechanical buttons. They are used in a variety of consumer and industrial applications, providing a reliable and durable solution.

 Capacitive Sensors

Capacitive sensors detect changes in capacitance between a sensor electrode and a target. They work by measuring the change in capacitance when an object approaches the sensor. TI's capacitive sensors, such as the FDC1004, use a switched-capacitor approach and include an active shield driver to minimize parasitic capacitance, making them highly accurate and robust.
