The capacitive measurement principle recognizes the approximation of the human hand. Static momentary sensors detect hands and objects, as long as the active surface finish. The hand sensors switch also by glass. Compared with mechanical switches the sensors work wear-free. Since you to touch is when there is no pressure is necessary. This increases the control comfort. LEDs as visual feedback signal the activation of the sensor. In the industry, the sensors as a start/stop button or acknowledgment button on machines application. On mobile machines and trailers can be the sensors as a button. You will also be used as a stop button or door opener.This text is machine translated.
