Inductive touch sensor

The mechanical design chapter discusses several factors that impact button sensitivity, including metal selection . Simple on and off buttons can be easily implemented using inductive sensing. The LDC portfolio boasts highly accurate, contactless force touch technology that can detect different levels of force to perform different actions. These buttons are reliable underwater, in debris-ridden environments, and in operation with gloves.

A new development kit from Texas Instruments can give you some hands-on experience with inductive - touch -sense technology.

However, the design of an inductive touch sensor does not require an in-depth understanding of those laws, so they will not be covered here.

They are available in the appendix of this .

The inductive touch solution can reliably operate in environments that have dirt, moisture, oil, or varying temperatures that pose issues for alternate sensing technologies. The LDCTOUCHCOMCOILEVM is designed to provide maximum flexibility for system prototyping in inductive touch applications and allows experimentation with different coil sizes. The sensor options on the inductive touch coil EVM include different coil geometries . The primary reasons are that it can reduce costs while being . This reduces total system cost compared with current solutions.

Microchip offers both capacitive and inductive touch sensing options. The key parameters of the LC sensor include frequency, effective parallel resistance RP, and quality factor Q. Capacitance to Digital Converters. Proximity sensing in any environment. Improves industrial design and cost effective solution.

Enables use of smaller sensors. Sliders, wheels, proximity and up to buttons. Sleek industrial designs: with seamless glass, plastic or metal surfaces. Supporting HMI in different shapes and sizes.

Inductance to Digital Converter . Reliability: no moving parts make the design less prone to failure. Harsh environment operation: Perfect for moisture sensitive or other . The recent surge in the number of capacitive sensors has been largely driven by the use of touch sensors for touch screens. Many current applications use active touch sensing technologies. Passive touch sensing technologies are, however, more adequate to implement low power or energy harvesting touch .
