Oil-resistant Limit Switch
last update: July 1, 2016
The results of a thorough analysis of the ingress paths of cutting oil show that the deterioration of cable sheaths is a large factor. The cable sheaths of OMRON’s Oil-resistant Components are made from fluororesin materials to provide maximum protection against the deterioration with a unique new concept. The result is an oil resistance impregnable to even highly aggressive cutting oils.
Fluororesin, which provides superior resistance to corrosion, is used for the outer cable sheath to suppress cable swelling and deterioration and prevent the ingress of cutting oil to the PCB section.
In addition to deterioration of cable sheaths, deterioration of the rubber used at joints and moving sections is also a major cause of ingress of cutting oil. In order to prevent rubber deterioration, OMRON’s Oil-resistant Components use a new fluorinated rubber at joints and moving sections. Combined with fluororesin cables, this double use of the strongest materials forms an impregnable wall of oil resistance.
Hydrogenated nitrile butadiene rubber (HNBR), which provides superior resistance to oil, was blended with fluororubber in a unique OMRON compound to develop a new rubber that provides superior resistance to both swelling and deterioration due to cutting oil. It is used in seals for joints and moving sections that prevent ingress to prevent deterioration and destruction of the seal due to cutting oil, resulting in increased oil resistance performance.
