The following guide provides a review of the types of proximity sensors for prolonged detection, followed by a look at capacitive sensing design specifically for occupancy-type solutions. A variety of ...

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 ...

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 ...

Sponsored by IDT: Thanks to the advances made in inductive position sensing, the technology is carving new paths in automotive design and leaving its optical and capacitive cousins in the dust.

There is a wide need for position, motion, and proximity sensing using low power for various applications. Capacitive, inductive, and Hall effect sensors are among the approaches for today’s low-power ...
