Safety Limit Switch
[email protected]
CSM_D4B-_N_DS_E_10_1
Robust safety limit switch with metal housing
Slow-action and snap-action contact with
certified direct opening operation
certification
• Direct opening mechanism (NC contacts only) added to
enable opening contacts when faults occur, such as fused
contacts.
• Safety of lever settings ensured using a mechanism that
engages a gear between the operating position indicator plate
and the lever.
• Equipped with a mechanism that indicates the applicable
operating zone, as well as push-button switching to control left
and right motion.
• Head seal structure strengthened to improve seal properties
(TÜV: IEC IP67, UL: NEMA 3, 4, 4X, 6P, and 13).
• Wide standard operating temperature range:
–40 to 80°C (standard type).
• Certified standards: UL, CSA, EN (TÜV), and CCC.
Note: Contact your sales representative for details on
models with safety standard certification.
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
Be sure to read the “Safety Precautions” on page 9.

Structure and Nomenclature
Structure
Head
Can be connected in any of four directions (except for
Roller Plunger Models, which can be connected at either
of 2 directions that differ by 90°)
The roller lever switch employs a
system which allows
selection of operation on only one
side (left or right)
or both sides without the use of
any tools.
Seal Ring
Sealing properties improved by using a X ring and
bearing-free structure.
Roller
Nylon rollers used for superior resistance to wear.
Lever (Form Lock Structure)
The lever has an operating position indication plate
and grooves that mate every 90° to prevent slipping
between the rotary axis and lever.
The operating position indicator plate
Built-in Switch
Direct opening mechanism used for NC contact to
separate contact for faults, such as contact welding.
The heights of the NC and NO terminals are different
to enable easier wiring.
Conduit Opening
G1/2 or M20
Cover
Ground Screw
Ground screws are provided on all

Application Precaution
Changing the Operating Direction
Operating section
(on back of Head)
Switches with Roller Levers
The operating direction of the lever can be easily
changed without using any tools. It can be set to
clockwise operation (CW) or counterclockwise
(CCW) operation.
Use the procedure given at the right to change
the operating direction.
Operating procedure
1. Remove the four Head set screws and remove the Head
from the Switch Box.
Head Cover
Operating
position
mark
(arrow)
2. Turn the bottom of the Head toward you, press in the Head
Cover shown in the diagram at the left, and turn the Cover
clockwise or counterclockwise.
Note: The factory setting is for “CW.CCW.”
3. The “CW” setting is for clockwise operation and the “CCW”
setting is for counterclockwise operation. Set the Cover to
the desired position.
Safety Precautions
Be sure to read the precautions for All Safety Limit Switches in the website at:http://www.ia.omron.com/.

Precautions
for Correct
Use
Supplementary comments on what to do
or avoid doing, to prevent failure to
operate, or undesirable effect on product
performance.
Use four M5 screws with washers to mount the standard model. Be
sure to apply the proper torque to tighten each screw.

Standard Model
Precautions for Safe Use
• Do not use the Switch submerged in oil or water, or in locations
continuously subject to splashes of oil or water. Doing so may
result in oil or water entering the Switch interior. (The IP67 degree
of protection specification for the Switch refers to water penetration
while the Switch is submersed in water for a specified period of
time.)
• Always attach the cover after completing wiring and before using
the Switch. Also, do not turn ON the Switch with the cover open.
Doing so may result in electric shock.

Changes in Actuator Mounting Position
• To change the angle of the lever, loosen the Allen-head bolts on
the side of the lever.
• The operating position indicator plate * has protruding parts which
engage with the lever, thus allowing changes to the lever position
by 90°.
• The back of the operating position indicator plate * has no
protruding parts. If this plate is turned over and attached, any angle
within a 360° range can be set. Do not turn over the plate, however,
when using the [email protected] as a switch with a certified direct opening
mechanism. For an SUVA- or BIA-certified application, make sure
that the lever engages with the operating position indicator plate
securely so that the lever will not slip.
* The operating position indicator plate: Refer to page 5.
Changes in Head Mounting Position
By removing the screws on the four corners of the head, the head can
be reset in any of four directions. Make sure that no foreign materials
will penetrate through the head.

Wiring
Conduit Opening
Do not connect the bare lead wires directly to the terminals but be
sure to connect each of them by using an insulation tube and M3.5
round crimp terminals and tighten each terminal screw within the
specified torque range.
The proper lead wire is 20 to 14 AWG (0.5 to 2.5 mm2) in size.

• Make sure that each connector is tightened within the specified
torque range.
The casing may be damaged if the connector is tightened
excessively.
• Use an OMRON SC-series Connector (sold separately) that is
