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.

Do not tighten the nuts with excessive force.
The maximum permissible tightening force of
each nut with a washer is 29.4 N·m.
Grounding of Antenna and Sensing
Object
<Size of Sensing Object>
<Conditions of Sensing Object>
• Grounded Object
• Non-grounded Object
• The detection of conductors (e.g., iron, stainless steel, aluminum,
• Non-conductive objects (e.g., plastic, ceramic, glass, and cloth
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.
objects) can be detected by grounding them indirectly.
(Refer to Application Examples on page 1.)
Contact with Grounded Conductor
The sensing object is equivalently grounded through
ground resistor R.
R: 3 kΩ max.
The sensing object must not come into contact with the human body
Contact with Non-grounded Conductor
The sensing object is equivalently grounded through capacitor C.
C: 30 pF min.
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.
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).

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 cm
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
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.

Otherwise, the D5C will not operate.
however, used in the 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.
