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 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 state-of-the-art sealing method that does not allow the creation of gaps.

OMRON’s unique over-molding method that combines forming and sealing methods with surface bonding techniques blocks the ingress of cutting oil through the joined surfaces into the connector.

[Patented] Smartclick Structure + O-ring

With traditional screw-tightened structures, differences in tightening torque made achieving oil resistance difficult. The Smartclick structure, however, locks in a single operation. The built-in O-ring at the lock position is dependably compressed to block the ingress of cutting oil. This structure eliminates the needs to manage screw tightening torque and prevents screw loosening due to vibration, which were issues in environments requiring oil resistance.
