Small Sealed Switch
[email protected]
CSM_D4E-_N_DS_E_5_1
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 [email protected] and D4E models.
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
Be sure to read Safety Precautions on page 9 to 10 and
Safety Precautions for All Limit Switches.

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.
Seal Packing (NBR)
· Seal packing withstands a pressure of 186 kPa.
Terminal Protection Cover
· [email protected] has a wide wiring space of
10 mm horizontally.
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.

Molded Terminal Models
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.

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.
Neon lamp
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.

Safety Precautions
Refer to Safety Precautions for All Limit Switches.
Precautions for Correct Use
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.
Not Suitable
Suitable
• 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.
Mounting Holes
Two, 4.3 dia. or M4 hole
• 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.
(2) Lightly push up the filling on the
left and right side alternately.
33±0.15
• 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.
Mounting Hole
14.5±0.2 dia.
• 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.

inserted.
