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 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 ...

In Part I of this series, we explored the differences between user interfaces based on mechanical buttons and those utilizing capacitive touch sensors. In Step 1 we discussed the look and feel of a ...

Capacitive touch sensors are based on the electrical capacitance of the human body. When, for example, a finger comes close to the sensor, it creates a capacitance to Earth with a value of 30 to 100 ...

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 ...

The FDA’s 2004 guidance on process analytic technology (PAT) created a sub-industry focused on “reducing production cycle times by using on-, in-, and/or at-line measurements and controls.” GEN ...

Capacitive sensors are found in a wide range of equipment, from consumer electronics to industrial/process control. Touch buttons are increasingly found in lamps and dimmers. Motion detectors can ...
