Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...

EBE sensors + motion is expanding its portfolio of capacitive input systems for industrial control concepts with the TCRC.

As with traditional mechanical switches, a user's interface experience with a capacitive sensor is directly related to the way the sensor responds (sensitivity) upon contact under all operating ...

New rectangular 8 mm by 16 mm inductive proximity sensors have been added to AutomationDirect’s sensor line-up in flush and non-flush mounting options, NO or NC output, and NPN or PNP logic.

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 ...

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 ...

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

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 ...

Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed such ...
