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 into the PCB inside the Sensor.

*The Strongest Material: Based on June 2016 OMRON investigation.

In addition to cable sheaths, joints, and moving sections, cutting oil enters most easily in gaps between different materials. OMRON’ s Oil-resistant Components completely block the ingress of cutting oil with a unique structure that does not allow the creation of gaps.

An aluminum ring bushing is compressed and deformed by a set screw to seal the structure by pressing against the fluororesin part of the fiber core. This prevents the ingress of cutting oil from the joined surfaces.
