Unique 18-mm-dia. Capacitive Touch
Switch with Choice of Three Actuators is
Activated with Only a Very Slight
Physical Contact
• Only a slight activation force is required, enabling detecting micro
deflections, thin wires, or thin-plate conductors (e.g., steel or
stainless).
Application possible for non-conductors by indirectly connecting to
ground.
• Instantaneous operation upon contact with extremely limited
hysteresis for high-precision position detection.
• Diameter of only 18 mm with standard built-in amplifier, operation
indicator, and sensitivity adjustment.
• Conforms to IEC IP67 *
• Freely replaceable antenna with screw mounting.
• Free attachment to enable changing the antenna shape according to
the application.
Be sure to read Safety Precautions on page 6 to 7 and
Safety Precautions for All Limit Switches.
* Malfunction may occur if used in locations subject to water or oil.

Safety Precautions
Refer to Safety Precautions for All Limit Switches.
CAUTIONS
Antenna
<Shape and Extension>
Make sure that the antenna does not come into contact
with the human body, otherwise an electric shock may
be received.
If a metal plate is used as an antenna by connecting it to the built-in
or separated antenna of the D5C, the surface area of the metal plate
must be 200 cm2 maximum (Fig. 1). The antenna can be extended,
provided that the total length of the antenna is 1 m maximum (Fig. 2)
and that the bottom of the antenna is at least 10 cm (Fig. 3) away from
the ground. Refer to the illustrations below
Precautions for Correct Use
The D5C may be damaged if the antenna is excessively large or
heavy or if the antenna is used in locations with excessive vibration or
shock. Be sure to check the locations before use.
Mounting
Do not tighten the nuts with excessive force.
The maximum permissible tightening force of
each nut with a washer is 29.4 N·m.

<Size of Sensing Object>
• Grounded Object
If the sensing object is the following grounded conductor, its size
will not affect the operation of the D5C. Check for the presence of
insulators sticking to the sensing object or the corrosion of the
sensing object, however, so that the ground resistance will not
exceed 3 kΩ.
<Parallel Arrangement>
If there are multiple D5Cs are located in parallel, make sure that the
distance between adjacent antennas is at least 3 cm.

Maintenance
R
• Make sure that the portion of the antenna that comes into contact
with sensing objects is free of oil, dirt, or rust, or any other insulator.
Otherwise, the D5C will not operate.
R: 3 kΩ max.
• The degree of protection of the D5C is IP67. The D5C cannot be,
however, used in the water or oil.
The sensing object must not come into contact with the human body
• Locations with Sprayed Water or Oil
• Non-grounded Object
The D5C may malfunction in locations where the D5C is frequently
exposed to sprayed water or oil. Especially, the D5C may
malfunction more frequently if it is exposed to sprayed water-
soluble cutting oil. In such locations, be sure to take appropriate
measures to protect the D5C from oil and water.
If the sensing object is the following non-grounded conductor, the
D5C will operate if the capacitance between the sensing object and
the ground is 30 pF or more. The larger the surface area of the
sensing object is, the higher its capacitance will be. The shorter the
distance between the sensing object and the ground is, the higher
the capacitance will be. Furthermore, the capacitance greatly
varies with the ground condition (e.g., dry sand, concrete, or wet
soil).
Wiring and Connections
• Be sure to wire the D5C correctly according to the color of each
cord. Incorrect wiring may damage the internal components of the
D5C or the D5C may malfunction.
• A maximum of two models can be connected in series provided that
100 to 240 V is supplied. DC models cannot be connected in series.
Contact with Non-grounded Conductor
The sensing object is equivalently grounded through capacitor C.
Generally, the conductor will
be detectable if the ambient
humidity is 60% to 70%RH and
the surface area of the conductor
is approximately 300 × 500 mm.

• Be sure to supply power to the D5C via the load. If power is supplied

<Conditions of Sensing Object>
Power
source
• The detection of conductors (e.g., iron, stainless steel, aluminum,
and brass objects) poses no particular problem. A conductor
coated with paint cannot be detected, however, because there is no
electrical continuity between the antenna and the conductor.
• Non-conductive objects (e.g., plastic, ceramic, glass, and cloth
objects) can be detected by grounding them indirectly.
(Refer to Application Examples on page 1.)
• If there are wire power lines or high-tension lines close to the cable
of the D5C, be sure to wire the cable of the D5C away from power
lines or high-tension lines or lay the cable in an exclusive, shielded
conduit.
• Remove the caution label on the end of the cable before wiring the
cable.

D5C
D5C-1A@0 (AC Models)
Others
• Be aware that the D5C-1A@0 not in operation has a leakage
current of approximately 2 mA. Especially, if the load is a relay with
a current flow of 10 mA or less, a reset failure may result due to the
residual voltage. Therefore, connect a bleeder resistor as shown
below so that the residual voltage will be less than the reset voltage
of the load.
• Do not disassemble the D5C, otherwise the internal wiring will be
damaged and the D5C will fail to operate.
• The sealing of the D5C uses nitrile butadiene rubber (NBR), which
is highly oil resistive. If exposed to some types of oil or chemical
indoors or outdoors, however, the NBR may deteriorate. Contact
your OMRON representative for details.
• When mounting the antenna to the D5C, be sure to tighten the
antenna to a torque of 0.39 to 0.83 N·m. If the antenna is not
tightened securely, the built-in contact may break.

• If an appropriate antenna is mounted to a free attachment model,
hold the nut on the outer side with a wrench so that the nut will not
move. Then tighten the nut on the inner side within a torque range
of 0.78 and 1.18 N·m.
The bleeder resistance and permissible power are obtained from
the following formula.

• If a DC relay or DC counter is used as a load connected through an
electronic timer or current rectification circuit, pay the utmost
attention so that the leakage current of the D5C AC model will not
cause the load to malfunction.
Direction

Sensitivity Adjustment
• The sensitivity of the D5C can be adjusted by turning the adjuster
on the rear side with a flat-blade screwdriver.
•
The sensitivity increases by turning the adjuster clockwise (max. 30 pF)
and decreases by turning the adjuster counterclockwise (min. 100 pF).
SENSI
Set point
• Be sure to turn the adjuster with a torque of 0.08 N·m or less. If
excessive torque is applied, the adjuster will break.
Grounding
<For DC and AC Models>
• In order to maintain the operational reliability of the D5C, be sure to
ground the blue or black wire of the power cable.
(Refer to “Output Circuit Diagram” on page 4.)
• Operation may fail if the D5C is not grounded.
<DC Models>
• The service power supply of the PC (Programmable Controller) is
not available to the D5C-1D@0. The negative line of the service
power supply of the PC is not grounded. Therefore, the D5C may
not operate.
Furthermore, if the negative line of the service power supply is
grounded, the noise resistance of the PC will drop.
<AC Models>
• Provided that single-phase 200 V is supplied to the D5C-1A@0, if
one phase is grounded, the power supply will be short-circuited and
a machinery breakdown will result. Use an isolating transformer
and ground the secondary side of the transformer instead.
• In the above case, be sure to ground the secondary side, otherwise
the D5C may not operate.
