■Characteristics
Note: 1. The above figures are initial values.
2. Contact your OMRON sales representative for measurement conditions of the repeat accuracy.
3. Life expectancy values are calculated at an operating temperature of 5
 C to 35  C, and an operating humidity of 40% to 70%.
Contact your OMRON sales representative for more detailed information on other operating environments.
4. The value indicates the operating position change rate for a change of 1
 C in the ambient temperature.
■Operating Characteristics
Note: 1. The operating position of these types is the same as the free position because of high sensitivity (repeat accuracy: 1 m m max.).
2. Total movement is 1.9 to 2.1 mm. Set the appropriate stroke (plunging depth) to 1.0 to 1.5 mm from the FP.

Precautions
■Correct Use
Handling of Fiber Cable
Do not pull or impose any force exceeding 29.42 N on the fiber
cable.
Make sure that the bending radius of the fiber cable is as large as
possible and at least 25 mm.
The 40-mm portion of the fiber cable on the connector end as
shown below must not be bent.
Do not impose compressing loads on the fiber cable.
The fiber cable can be cut with OMRON’s E39-F4 Cutting Tool.
Do not impose any force exceeding 29.42 N on the cord, other-
wise the cord may break. Make sure that the bending radius of
the cord is at least 20 mm.
Mounting
For the mounting dimensions, refer to the following figures and tables.
Do not tighten the nut with too much force.
Be sure to apply the clamping torque shown in this table.
When mounting the Switch to a panel, be sure to use the toothed
lock washer attache as an accessory (to M5, M8, and M16 types
only). Use the washer on the panel surface opposite the object to
be detected by the Switch.

Connection of Contact Output
Connection of Solid-state Output
Be sure to connect the load to the power source in series.
The operating state of the Switch can be checked by the LED
operation indicator (illuminants when the Switch is in operation)
incorporated in the solid-state output circuit.
The output residual voltage is approximately 3 V. Therefore, exer-
cise care when selecting the load and setting the supply voltage.
The residual voltage, however, can be easily calculated because
it is almost constant and is free from the influence of fluctuation in
the load current.
Example:
1. In the above circuit, suppose the MY relay rated at 12 VDC
is used as the load. Since the must operate voltage of the
relay is 80% or less than the rated voltage, it is 12 x 0.8 =
9.6 V. The supply voltage, in turn, is 3 + 9.6 = 12.6 V.
Therefore, the relay may not operate with a 12 V power
source.
2. However, if the relay rated at 24 VDC is employed, the must
operate voltage and supply voltage of the relay are respec-
tively 19.2 V and 22.2 V. The relay therefore can operate
with a 24 V power source.
When a solid-state circuit is turned OFF, leakage current of 0.15
mA (max.) flows, causing some voltages to remain in the load.
For this reason, be sure to check the must release voltage of the
load before using it.
Series Connection of Switches
The Solid-state Output-type Switches must not be connected in
series. To obtain the same effect as a series connection, form an
AND gate with a relay inserted between the Switch and load.
Parallel Connection of Switches
In principle, two or more D5A’s should not be used in an OR con-
figuration.
However, they can be connected in parallel provided that both
switches A and B in the above figure do not operate at the same
time and that the load does not have to be kept energized. In this
circuit, however, the leakage current is increased, multiplied by
the number of Switches connected in parallel. Consequently, the
Switch may not release properly. To keep the load energized, con-
nect a relay to each of the Switches as shown below.
Connection to Power Source
Be sure to connect the Switch to the power source via the load. If
directly connected to the power source, the internal elements of
the Switch may be damaged.
Correctly connect the white and black lead wires to the positive
and negative sides, respectively, of the power source. Although
the D5A will not be damaged even if the polarity is reversed by
mistake, if this happens, the Switch maintains the ON state (i.e.,
the contact is kept open) regardless of the presence or absence
of the object to be detected.
Others
Adjust the mounting of the D5A until the stroke of the pin plunger
is aligned with the stroke of the operating body. Special attention
should be paid to the ceramic pushbutton unit. It might be dam-
aged if undue shock is applied.
The harder the material for the dog and the more solidly the
mounting base is fitted, the more accurately a minute displace-
ment is detected.

When a limit switch type is used, apply grease to the dog to
reduce friction between it and the plunger. Do not apply grease to
pin plungers, otherwise the grease may stick to the contacts or
generate gas that may cause contact failures.
Be sure to use dogs made of hard materials for bevel or top
plungers and apply grease to the surface of the dogs. The hard-
ness (Hv) of a bevel plunger is 2,000 or over, for which it is recom-
mended that a dog that has an Hv value of 1,000 or less be used.
Do not fail to provide a stopper so as to prevent the enclosure of
the D5A from being used as the stoppers.
Attach an appropriate cover for the protection of the D5A from
machining oil or cuttings. No protective cover is, however, pro-
vided together with the Switch.
Exercise care that excessive force is not applied to the ceramic
plunger of M5, M8, or slim type.
If the possibility exists that strong shock may be applied to the
plunger when the Switch is being mounted, use a protective cap.
The plunger may not release if it is depressed with too great a
force. Set its stroke by referring to the OT value indicated in Oper-
ating Characteristics.
Do not mount the Switch with its nameplate facing downwards
(i.e., in the direction of gravity), otherwise the oil drain hole will not
work effectively.
