Proximity switches for construction equipment - high pressure resistance and thermal stability

VS proximity switches are highly durable, have high frequency reciprocal signal switching, are stable in high

temperature conditions and, due to the specially

designed housing material, can be used in Thanks to the specially designed housing material, they work well

in extreme high pressure environments. If required,

we can also supply proximity switches with "micron" resolution distances on request.

VS-Sensorik high pressure proximity switches are the main supplier of high pressure proximity switches

for the hydraulic systems of Putzmeister construction machinery: targeted Sensing recognises

ferromagnets, while non-ferromagnets do not interfere with their signals. Putzmeister Elephant Magnetic
