Omron D4ER-@N Limit Switches use high-frequency oscillation. They resist heat, chemicals, and water better than Rectangular Sensors. They are available in both shielded and unshielded models.
Proximity Sensors are available in models using high-frequency oscillation to detect ferrous and non-ferrous metal objects and in capacitive models to detect non-metal objects. Models are available with environment resistance, heat resistance, resistance to chemicals, and resistance to water.

- The following ratings may vary depending on the model. Contact your OMRON representative for further
- The IP67G is the degree of protection that 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.
- 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.
*This value represents the condition when the Switch is shipped from the factory.
