Capacitive touch sensing is a popular alternative to mechanical switches and knobs in consumer electronics, white goods, and automotive applications. In traditional designs, capacitive touch sensing ...

Inherently noncontacting capacitive sensors hold a charge differential and register when passing objects alter it. Either one metal plate generates and Inherently noncontacting capacitive sensors hold ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

Capacitive-proximity sensors have been used widely in industrial applications such as counting products on a conveyor, detecting position of valves, presence of objects etc. In recent years, the use ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...

Non-contact displacement measurements can be made rapidly and with high precision using capacitive sensors over a modest range. The main features are: Capacitive sensing is a non-contact measurement ...

Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, ...

If you do any kind of machining, 3D printing, or PCB layout, you probably have at least considered buying a pair of calipers. Old-fashioned ones had a dial and were mechanical devices, but lately, ...
