If you’re the person tasked with controlling the level of fly ash in collection hoppers, you know how difficult the application can be. What at first looks like a simple measurement quickly proves to ...

It isn't easy being an electrical or electronics engineer in the automotive industry. Mechanical engineers that focus on cams, compression, and horsepower are more the norm, and often times electrical ...

Topre includes a capacitive non-contact switch with this series. The REALFORCE R3S English layout model, introduced in Juneis available in an English layout. It adopts a capacitance non-contact switch ...

Capacitive touch switches work by measuring the change in capacitance of a PCB (printed-circuit-board) pattern depending on the placement of a user’s finger over a sensing pad. Capacitive switches are ...

This PLL-based circuit implements a touch-switch circuit using the PC board or small metal pads as sensors; it is radiometric and thus insensitive to changes in temperature and supply voltage.

Electromechanical switches are simple, cheap, and widely available (Fig. 1). However, they’re also plagued with a number of disadvantages, including wear with repeated use, and the potential for ...

NXP Semiconductors N.V. today announced a complete family of self-calibrating capacitive touch and proximity switches designed for harsh environments. The PCF8883 and PCF8885, along with the ...

It has been announced that the Korean Leopold brand has released the "FC660C" line of high-end keyboards in a tiny size. A product that incorporates the capacitive contactless switch from Topre. In ...

A new line of capacitive proximity switches monitors liquids, pastes, and bulk materials — even through nonmetallic dividing walls. The devices can also be used as limit switches, contact-free ...
