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.
