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 ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

Designing with high-fidelity capacitive proximity sensors requires careful consideration of mechanical design, sensor placement/design, and end-application operating environments. Careful evaluation ...

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 ...

SICK, one of the world’s leading manufacturers of sensors, safety systems, machine vision, encoders and automatic identification solutions for factory and logistics automation, announced the launch of ...

Capacitive proximity sensors allow sensing of metal and non-metal objects through insulating materials such as wood or plastic and are often used to sense fill levels of liquids or powders. New lower ...

One of the backbones to the success of any automated process is the accuracy to which one can detect and measure the various elements involved. Whether the process requires precise measurement and ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...

With increased automation of complex production systems, components that are capable of acquiring and transmitting information regarding the production process become necessary. Proximity sensors -- ...

A device that senses when another object is close by. In a mobile phone, a proximity sensor is most commonly used to detect when the phone is held to the face. Specifically, the sensor detects human ...
