Oil-resistant Limit Switches

D4ER-@N

Even Better Oil Resistance Than

D4E-N Switches

• HNBR/fluororubber used for superior resistance to oil.

Prevents infiltration of oil from moving sections.

• Fluorine resin cable that withstands cutting oils is

provided as a standard feature.

• Models available with SmartClick connectors for each

connection.

• Minute load model with gold cladding is optimal for

electronic control.

• Approved by EN (TÜV).

• Same mounting pitch as D4E-N Switches.

• IP67G degree of protection (JIS C0920 Annex 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.

Preliminary Version D4ER-@N 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. Rubber cap (HNBR/fluororubber) · Improved oil resistance.
