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

The results of a through 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 to the PCB section.

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

No Cutting Oil Ingress by Any Path The Strongest Material New Rubber Material Combining HNBR and Fluororubber

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.

OMRON-developed Rubber Blocks Ingress through Joints and Moving Sections

[Patented] New Rubber Material Combining HNBR and Fluororubber

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.

This new material combines the benefits of HNBR and fluororubber

Note: 1. The following values are initial values.
2. The following ratings may vary depending on the model. Contact your OMRON representative for further details.
*1. The IP67G is the degree of protection which is defined according to the JIS (Japanese Industrial Standards).
The IP67 indicates the same level of protection as defined by the IEC, and the G indicates that a device has resistance to oil.
*2. The Oil-resistant Component Evaluation Standards are OMRON’s own durability evaluation standards.
The Pre-wired Connector type meets the degree of protection when it is correctly connected with an XS5[]R Oil-resistant Connector.
The degree of protection is not satisfied with the part where there is no XS5FR Oil-resistant Connector connected and cable wires are uncovered. And as for the Cable type, the degree of protection is not satisfied with the part where cable wires are uncovered.
*3. This value represents the condition when the Switch is shipped from the factory.
