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 ...

The model 720 is a low-cost, compact capacitance vacuum gauge (CVG) based on the companyÕs variable capacitive sensor design. It produces a 0 to 5 Vdc or 0 to 10 Vdc output that is linear with ...

Touch sensors have been around for years, but recent advances in mixed signal programmable devices are making capacitance-based touch sensors a practical and value-added alternative to mechanical ...

The latest generation of handheld personal consumer electronic devices, with their highly sensitive and intuitive user interfaces based around projected capacitive (p-cap) touchscreens, have begun to ...

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 ...

This article provides an overview of capacitive touchscreen technology and describes the challenges inherent in implementing this technology in handheld devices. Ever since Apple launched the iPhone ...

The capacitive touch human-machine interface (HMI) is a critical aspect of modern electronics. It is how we interact with our devices, making it an integral part of wearables, smart home products and ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...
