Enclosed Switch
D4MC
CSM_D4MC_DS_E_2_2
Economical, High Utility Enclosed Switch
• Enclosed Switches with Built-in Basic Switches for High
Repeatability and Durability of 10 Million Operations Minimum.
• Panel mount versions have the same operating position as
Z Basic Switch.
• Suitable for applications demanding higher mechanical
strength, dustproof and drip-proof properties than those
on basic switches.
• Resin molded terminal versions are available.
• Approved by UL, CSA, and CCC (Chinese standard).
(Ask your OMRON representative for information on
approved models.)
Be sure to read Safety Precautions on page 5 and Safety Precautions for All
Limit Switches.

Safety Precautions
Refer to Safety Precautions for All Limit Switches.
Precautions for 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
• When mounting the Terminal Protective Cover to the case, align the
cover on the case and then press the cover down to mount it firmly.
If the cover is pressed down in an inclined position, rubber packing
will deform and thus affect the sealing capability.
Suitable
Rubber packing
Rubber packing
Mounting
• 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.
Operating
Excessive dog angle, operating speed, or overtravel (OT) may
damage the actuator. Check that OT has a sufficient margin. The
actual OT should be rated OT × 0.7 to 1.
• When mounting the Switch with screws on a side surface, fasten
the Switch with M4 screws and use washers, spring washers, etc.,
to ensure secure mounting.
Mounting Holes
Two, 4.3-dia.
or M4 screw holes
25.4±0.15
• When mounting the Panel Mount-type Switch (D4MC-5000, D4MC5020, or D4MC-5040) with screws on a side surface, remove the
hexagonal nuts from the actuator.
• When mounting the panel mount type on a panel, be careful not to
tighten to an excessive torque. Tightening the screws to a torque
exceeding 4.91 N·m will cause the plunger to fail.

Handling
• Do not expose the Switch to water exceeding +60°C or use it in
steam.
• Do not use the Switch in oil or water.
• An 8.5-dia. to 10.5-dia. cable can be applied as seal rubber for the
lead wire outlet. (Use two- or three-core cable of VCT1.25 mm2.)
• When detaching the Terminal Protective Cover, insert a
screwdriver and apply a force in the opening direction. Do not use
excess force to remove the cover. Doing so may cause deformation
in the fitting section and reduce the holding force.
