Safety Precautions
Refer to Safety Precautions for All Limit Switches.
Make sure that the antenna does not come into contact
with the human body, otherwise an electric shock may
be received.
Mounting
Do not tighten the nuts with excessive force.
Themaximumpermissibletighteningforceof
each nut with a washer is 29.4 N·m.
Grounding of Antenna and Sensing
Object
<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.
Contact with Grounded Conductor
The sensing object is equivalently grounded through
ground resistor R.
R: 3 kΩmax.
The sensing object must not come into contact with the human body
•Non-grounded Object
If the sensing object is the following non-grounded conductor, the
D5Cwilloperateif the capacitancebetweenthesensing object and
the ground is 30 pF or more. The larger the surface area of the
sensingobject is, the higheritscapacitance will be. The shorterthe
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).
Contact with Non-grounded Conductor
The sensing object is equivalently grounded through capacitor C.
C: 30 pF min.
<Conditions of Sensing Object>
•The detection of conductors (e.g., iron, stainless steel, aluminum,
and brass objects) poses no particular problem. A conductor
coatedwithpaint cannot be detected, however,becausethere 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.)
Antenna
<Shape and Extension>
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 cm2maximum (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 ofthe antenna is at least 10 cm (Fig. 3) awayfrom
the ground. Refer to the illustrations below
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.
<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
•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.
•The degree of protection of the D5C is IP67. The D5C cannot be,
however, used in the water or oil.
•Locations with Sprayed Water or Oil
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.
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.
•Amaximumof two models canbeconnectedinseries provided that
100 to 240 V is supplied.DC models cannot be connected in series.
•Besureto supply powertothe D5Cviatheload.If poweris supplied
to the D5C directly, the fuse will blow.
•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)
•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.
The bleeder resistance and permissible power are obtained from
the following formula.
R≤(KΩ) P> (mW)
P: W number of bleeder load (Practically, the wattage must be a few
times larger than the obtainable value.)
I: Load current (mA)
•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.
Sensitivity Adjustment
•The sensitivity of the D5C can be adjusted by turning the adjuster
on the rear side with a flat-blade screwdriver.
• Thesensitivity increases by turning the adjuster clockwise(max.30pF)
and decreases by turning the adjuster counterclockwise (min. 100 pF).
•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
onephase is grounded,thepower supplywillbe 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.
The lead wire colors of the D5C have been changed in compliance with the
latest applicable JIS standards. Colors in parentheses are previous ones.
Others
•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.
