provided as standard.
•
Pre-wired and connector cable models
available.
Smartclick connectors for easy connection.
•
Minute load model with gold cladding is optimal for
electronic control.
•
Approved by EN (TÜV).

*
Be sure to read
Safety Precautions
on pages 37 to 38 and
Safety Precautions for All Limit Switches.
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
* 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.

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.

Structure and Nomenclature
Structure
Movable Plunger
Built-in Switch
· Switch cover ensures high insulation
between
the terminals
and die-cast. Double insulation means that grounding is
unnecessary.
Meets EN standards.
· Prevents the movable piece from
being
pushed in too far, and
thereby contributes to a longer service life.
Die-cast Case
· Zinc die-cast case is anti-corrosive and tough.
Wiring Ease
· Wiring made easier
using
plug-in connectors.
Rubber cap (Material combining
HNBR and fluororubber)
· Improved oil resistance.
Terminal Protection Cover
Degree of Protection
The D4ER-@N uses rubber seals to provide a protective structure for the charged parts to achieve an IP rating of IP67G* (JIS C 0920).
The charged parts in the switching section are sealed with the two rubber seals shown in figure 1. The charged parts in the terminal section are
sealed with the two rubber seals shown in figure 2.
Material combining HNBR and fluororubber with excellent resistance to oil is used for the rubber seals.
