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.

Be sure to read Safety Precautions on page 9 to 10 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.

Movable Plunger

Rubber Cap (NBR)

· Rubber cap provides a tight seal and

ensures a long service life and

smooth reset at low temperatures.

Seal Packing (NBR)

Terminal Protection Cover

· D4E-@N has a wide wiring space of

10 mm horizontally. Screw Terminal

· Screw terminal incorporates a M3 screw with a toothed washer.

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.

Die-cast Case

· Zinc die-cast case is anti-corrosive and tough.

Wiring Ease

· Wired made easier using

(D4CC-type) plug-in connector.

Built-in Switch

Prevents the movable piece from being pushed in too far, and

thereby contributes to a longer service life.

Switch cover ensures high insulation between the terminals

and die-cast. Double insulation means that grounding is

unnecessary. Meets UL, CSA, and EN standards.

· Seal packing withstands a pressure of 186 kPa.

Molded Terminal Models

Operation of Indicator-equipped Models

•The molded terminal model may be equipped with an operation indicator (neon lamp or LED) upon request to facilitate maintenance and

inspection.

•The operation indicator is designed to illuminate when the Switch is not operating. (Because of the molded terminal model, any change to the

Switch wiring cannot be made.)

AC Operation

•The operating voltage is 90 to 250 VAC.

•There is no difference in operating characteristics between D4E-

@N AC Models and corresponding D4E-@N Standard Models.

•There is no difference in dimensions between D4E-@N AC Models

and D4E-@N Standard Models.

Example:

Add “L” at the frond of “N”, which is suffix of a part number.

Basic type: D4E-1A23N

When placing your order for the molded terminal model with an neon

lamp operation indicator, specify the model number as D4E-1A23LN.

Internal Circuit

DC Operation

•LED indicator is provided.

•

As a rectifier stack is incorporated, into the unit and no directionality

exists for connection of + and

−

, this type can also be operated on AC.

•Voltage ratings of LED indicators are as shown in the table below.

Example:

Add “L2” at the frond of “N”, which is suffix of a part number.

Basic Model: The model number of the D4E-1A23N with a built-in

24-V LED indicator is D4E-1A23L2N.

Internal Circuit

The molded-terminal model is available with

right-hand and left-hand leads and is

recommended for use where the Switch is

exposed to dust, oil or moisture. It can be used

like a screw-terminal model (with a cable), and

the dimensions and operating characteristics

are the same as for standard models.

Safety Precautions

Refer to Safety Precautions for All Limit Switches.

Operating Environment

•Seal material may deteriorate if a Switch is used outdoor or where

subject to special cutting oils, solvents, or chemicals. Always

appraise performance under actual application conditions and set

suitable maintenance and replacement periods.

•Install Switches where they will not be directly subject to cutting

chips, dust, or dirt. The Actuator and Switch must also be protected

from the accumulation of cutting chips or sludge.

•Constantly subjecting a Switch to vibration or shock can result in

wear, which can lead to contact interference with contacts,

operation failure, reduced durability, and other problems.

Excessive vibration or shock can lead to false contact operation or

damage. Install Switches in locations not subject to shock and

vibration and in orientations that will not produce resonance.

•The Switches have physical contacts. Using them in environments

containing silicon gas will result in the formation of silicon oxide

(SiO2) due to arc energy. If silicon oxide accumulates on the

contacts, contact interference can occur. If silicon oil, silicon filling

agents, silicon cables, or other silicon products are present near the

Switch, suppress arcing with contact protective circuits (surge

killers) or remove the source of silicon gas.

•Do not solder the screw terminals.

•Sealing materials may deteriorate when used outdoors or when

exposed to cutting oil, solvents, or chemicals. Check this on actual

equipment and, if deterioration is foreseen, consult your OMRON

representative in advance.

•If the one-touch connector is to be mounted onto the switch body,

lightly push up the fitting so that the switch body can then be

inserted into the clamp.

•Be sure that the clamp is inserted to the full depth, because the

Switch will not function properly if one of the clamps is improperly

inserted.

•If the clamp is properly inserted up to the full depth, it will not slide

out easily. Be sure to carefully confirm all the above items.

•Be sure to connect a fuse with a breaking current 1.5 to 2 times the

rated current to the Limit Switch in series in order to protect the

Limit Switch from damage due to short-circuiting. When using the

Limit under the EN ratings, use a gI or gG 10-A fuse that conforms

to IEC60269.

Mounting

•Secure the Switch with two M4 screws and washers. The tightening

torque applied to each terminal must be 1.18 to 1.37 N·m. Tighten

the screws to the specified torque. An excessive tightening torque

may damage the Switch and cause a malfunction.

•When mounting the panel mount-type Switch with screws on a side

surface, remove the hexagonal nuts from the actuator.

•When mounting the panel mount type on a panel, tighten the

hexagonal nuts of the actuator to a torque less than 7.85 N·m.

•Operating method, shape of cam or dog, operating frequency, and

the overtravel (OT) have significant effect on the service life and

precision of the Limit Switch. Make sure that the shape of the cam

is smooth enough.

•Check that OT has a sufficient margin. The actual OT should be

rated OT × 0.7 to 1.

•Do not change the operating position by remodeling the actuator.

Wiring

When wiring screw terminals, M3-size round solderless terminals with

an insulation tube is recommended. The conductor size should be

0.75 mm2 and cable diameter should be 7 mm.

Precautions for Correct Use
