Small Sealed Switch
D4E-@N
Slim and Compact Switch with Better Seal
and Ensuring Longer Service Life than D4E
•
Flat springs with an improved lever ratio of the built-in switch ensure
smooth snap action and long life expectancy.
•
Protection cover protects the built-in switch from dust and oil. Plunger
incorporates a tough seal cap that lasts for a long time.
•
One touch connector eliminates need for tedious wiring operations and
reduces downtime for wiring and maintenance (models with standard,
easy-to-use screw terminals are also available).
•
Minute load model with gold cladding is optimal for electronic control.
•
Molded terminal types as well as molded terminal types with operating
indicator lamps are available for screw terminal systems.
•
Approved by EN, UL, CSA, and CCC (Chinese standard).
(Ask your OMRON representative for Information on approved models.)
•
No difference in mounting pitch and characteristics between D4E-@N
and D4E models.

Structure and Nomenclature
Structure
Movable Plunger
Rubber Cap (NBR)
· Rubber cap provides a tight seal and
ensures a long service life and
smooth reset at low temperatures.
Bearing
· The bearing load strength has been increased to prevent faulty
resetting of the bearing, which may occur when the roller is
pressed with excessive force.
Built-in Switch
· Switch cover ensures high insulation between the terminals
and die-cast. Double insulation means that grounding is
unnecessary. Meets UL, CSA, and 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
· Wired made easier using
(D4CC-type) plug-in connector.
Screw Terminal
· Screw terminal incorporates a M3 screw with a toothed washer.
Seal Packing (NBR)
· Seal packing withstands a pressure of 186 kPa.
Terminal Protection Cover
· D4E-@N has a wide wiring space of
10 mm horizontally.
