Oil-resistant Proximity Sensors


Proximity Sensors That Withstand Cutting Oil to Reduce Failures Caused by Ingress of Cutting Oil

No Cutting Oil Ingress by Any Path The Strongest Material Cables with Fluororesin Sheaths

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 Blocks Ingress from Cables

[Patent Pending] Fluororesin Outer Cable Sheath

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.

No Cutting Oil Ingress by Any Path Advanced Sealing Method

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.

Ingress through Cable Joints Is Blocked with a State-of-the-art Sealing Method

[Patent Pending] Heat-Sealing Method

A fluororesin cable is heat-welded with a fluoro component which has a high bondability and a melting point close to that of the cable. This blocks the ingress of cutting oil from the joined surfaces.
