General-purpose Limit Switch
[email protected]
CSM_D4A-_N_DS_E_4_2
The Limit Switch with Better Seal,
Shock Resistance, and Strength
• A double seal on the head, a complete gasket cover, and
other features ensure a better seal (meets UL NEMA 3, 4,
4X, 6P, 12, 13).
• Wide standard operating temperature range:
−40°C to +100°C (standard type).
• Models with fluoro-rubber available for greater resistance
to chemicals.
• Block mounting method also reduces downtime for
maintenance.
• DPDT, double-break models available for complex
operations.
• Approved by UL, CSA, and CCC (Chinese standard).
(Ask your OMRON representative for information on
approved model.)
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 14 to 15 and
Safety Precautions for All Limit Switches.

Structure and Nomenclature
Structure (DPDT Double-break)
Head
With the Roller Lever and Side Plunger Switches, the
direction of the switch head can be varied to any of the four
directions by loosing the roller lever switch screws at the
four corners of the head.
Roller
The roller actuator is made of hardened
stainless steel and excels in resistance to
wear.
Lever
The Roller Lever Switch
employs a system which
allows selection of the
operation of only one side
(left or right) or both sides
without use of any tools.
Easy-maintenance Block Mounting
Block mounting makes it possible to easily assemble
or disassemble the head, switch body, and
receptacle of the [email protected] by tightening or loosening
the attached screws.
With the Roller Lever Switch, the lever can
be installed anywhere in a 360° range (180°
if the lever is reversed and attached to
the shaft).
Head
Oil Seal
Improved sealing property is ensured with a
double-seal construction (a oil seal plus an
X-ring seal).
Operating Position
Mark (arrow)
Actuator
Bearings
The copper-alloy bearings ensure long life
expectancy.
Switch Box
Boasts long life expectancy (50 million
mechanical operations or more with the
2-pole Double-break Switches and
30 million mechanical operations or more
with the DPDT Double-break Switches).
Receptacle
The plug-in type receptacle provides adequate
space for wiring.
Switch
box
Ground Terminal Screw
A ground terminal is provided to enhance
safety.
Conduit Opening *1, *2
G 1/2 conduit threads featuring high sealing
property are used. (Refer to Limit Switch
Connectors for details on SC connectors).
A terminal box with 1/2-14NPT conduit threads
is also available on request.
Switch Box Screw
Sealed Gasket
The employed full-cover
method prevents the gasket
from direct exposure to oil
or water spray.
Receptacle
A Phillips screw is used to secure the switch
housing for ease of use, and features a
measure to prevent the screw from coming off.
Note: 1. NBR is used in rubber components.
Fluoro-rubber sealed types use fluoro-rubber.
2. For Roller Levers, there is some lever play in the free position (about 2 mm), but this is due to the structure of the head and does not interfere with performance.
*1. A Receptacle and Terminal Box with 1/2-14NPT conduit threads are also available for the North America market.
*2. The conduit thread indication has been changed from “PF1/2” to “G1/2” accompanying the JIS B 0202 revision.
This changes applies only to the indication; thread sizes and pitches have not been affected.

Note: No D4A-0003N or D4A-0004N head should be used with the adjustable roller lever or mechanical malfunctioning could result because the total weight of the
adjustable roller lever is comparatively large. Use a standard-load head (D4A-0001N or D4A-0002N) instead.

Head and Lever Positions
• The operating head can be positioned
and locked in any of four 90° positions
and a lever can lock in any position
through 360° around the shaft of the Limit
Switch. Furthermore, the lever can be
reversed and attached to the shaft (refer
to the figures below on the right hand
side). Therefore the roller is compatible
with a wide movement range of a dog.
• A Fork Lever Lock can be used with
maintained models (D4A-0005N) only.
Remove the head from the
Switch by loosening the screws
(the screws can be loosened
but not removed from the head).
The operating head can be
positioned and locked in
any of four 90° positions.
The lever can lock in any position through 360° around
the shaft. The lever can be reversed and attached to the
shaft, in which case the switching operation should
complete in a range of 0° to 180°.

There are four kinds of fork lever locks.
The position of each roller is different.
It is possible to use D4A-E00 through

before attaching.
They can be used with D4A-@@05N

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
The lighting mode of the operation indicator can be changed easily
between two modes: lighting when the Switch is operating and
lighting when the Switch is not operating.

Internal circuits
• 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.

*1. The lamp is lit when the actuator is at the free position.
The lamp will be off when the contacts of the Limit Switch have been
actuated and snapped to each other at the operating position.
*2. The lamp is lit when the contacts have been released and snapped only from
the operating position.
Change the lighting mode as follows:
1. Push the claw securing
the lamp section to the
right (do not push
strongly).
2. Remove the lamp
section.
3. Mount the lamp section
so that legend “NC-ON”
or “NO-ON” will appear
in the display window.
Changing the Operating Direction
Roller Lever Switch
The head of the side rotary type can be converted in seconds to CW,
CCW, or both-way operation. Follow the procedures on the right hand
side for conversion (not applicable to the Maintained, Sequential
Operating, Center Neutral Operating Switches).
Operating Part (Rear of Head)
Operating position arrow marks
Procedures
1. Dismount the head by loosening the
four screws that secure it.
2. Turn over the head to set the desired
operation (CW, CCW, or both). The
desired side can be selected by setting the mode selector knob shown in
the figure. This knob is factory set to
the “CW+CCW” (both-way operation)
position.
3. When set to the CW position, the
head rotates in clockwise direction.
When set to the CCW position, the
head rotates in counterclockwise direction.
In either case, be sure to accurately
align the arrow mark to the setting position.
In either case, the lamp will not light when the load is ON.

Screw Tightening Torques for Heads and Switch Boxes
Appropriate Tightening Torque
To maintain the high sealing capability of the Limit Switch, tighten the
screws for the head and switch box with the following torques:
A loose screw may cause malfunctions. Be sure to tighten each screw
to the proper tightening torque as shown in the table.
Head (four 12-mm M4 screws): 1.2 to 1.4 N·m
Switch box (two 20-mm M5 screws): 2.4 to 2.7 N·m
Solderless Terminals
The [email protected] with DPDT double-break incorporates solderless
terminals.
Operation
• The operating methods, cam and dog shapes, operating frequency,
and overtravel (OT) have a significant effect on the service life and
accuracy of the Limit Switch. The shape of the cam should be as
smooth as possible.
• A marginal overtravel (OT) value should be set. The ideal value is
the rated OT value x 0.7.
• The actuator should not be remodeled to change the operating
position.
Connectors
To satisfy IP67, apply sealing tape to the connector conduit.
Appropriate external diameter of cables is 5.5 to 14 dia.
Use OMRON’s [email protected] Series.
Tighten the Connectors to a torque of 1.8 to 2.2 N·m.
Maintenance and Repair
The user must not maintain or repair equipment incorporating any
D4A-N model. Contact the manufacturer of the equipment for any
maintenance or repairs required.
