Inductive Sensors

How we work
As inductive proximity switches we have been equipped with an LC resonance circuit which consists of a capacitor and a coil which produce a high-frequency magnetic field at the active sensor surface. As soon as an electrically conductive object approaches this surface, a part of the electromagnetic energy is absorbed. Thus, an attenuation is caused and the amplitude of the oscillator decreases. As there is a direct relationship between amplitude and the distance of the conductive objects, a signal is released as soon as the object has achieved a defined operating distance.

What we can do
We operate in a completely non-contact mode and thus are not subject to any mechanical wear. Moreover, we are insensitive to any extreme environmental conditions and thus are an ideal choice for applications, in which absolute reliability and robustness is needed and superior switch accuracy and high switching frequencies are required. This is the reason why millions of inductive proximity switches like us are found in automatic processes - in machine construction as well as in the automotive field, in chemical apparatuses, in warehouses and conveying systems, in the textile or packaging industries.

What makes us so special
We are able to recognize metal objects at a distance of 100 mm. For this purpose we come in various constructions - from cylinders with a diameter as from 3 mm up to rectangular sensors with an edge length of 180 x 180 mm. Our housings come in a number of different synthetic materials or metal, and thus are suitable for a large number of applications. Our electric properties comprise 2, 3, 4 wire DC, AC, NAMUR and AS-Interface interfaces.
