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.
