Abstract
The invention relates to a capactive proximity sensor for detecting component belts, comprising at least two electrically conductive sensor surfaces (151, 152) which are arranged opposite each other on a non-conducting substrate having a low dielectricity number, whereby the component belts which are to be detected are detected in the millimetre range as a result of the low dielectric number of the substrate material and the geometric arrangement of the sensor surfaces (151, 152).
Claims20
Capacitive proximity sensor for detecting component tapes, said sensor having
- an electrically non-conducting substrate made of low dielectric constant material, and
- at least two electrically conductive sensor surfaces (151, 152) implemented facing one another on the substrate,
- so that because of the dielectric constant of the substrate material and the arrangement of the sensor surfaces (151, 152) on the substrate, component tapes (200) to be detected can be detected in the millimeter range.
Capacitive proximity sensor according to claim 7, 9 or 10, wherein the first sensor surface is electrically connected to a reference potential.
Component feeding device according to one of the preceding claims,
- wherein the sensor is integral with a feeding channel through which the components can be transported to the unloading position.
Component feeding device according to one of the preceding claims, additionally having an evaluation device by which a sensor output signal can be processed.
