Safety Precautions
Refer to Safety Precautions for All Limit Switches.
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 R20 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 cable, otherwise
the cord may break. Make sure that the bending radius of the cable
is at least 20 mm.
Mounting
•The screw sections of cases for M5, M8, and M16 types have
special dimensions. Do not use the mounting dimensions specified
for standard types.
•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
torque shown in this table.
•When mounting the Switch to a panel, be sure to use the toothed
lock washer attached 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
Consideration of polarity is not required.
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 (lights when the Switch is in operation)
incorporated in the solid-state output circuit.
•The output residual voltage is approximately 3 V. Therefore,
exercise 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.
Note: The lead wire colors of the D5A have been changed in compliance with
the latest applicable JIS standards.
Colors in parentheses are previous ones.
[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 × 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 respectively 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
configuration.
•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,
connect 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.
The core wire colors have been changed to meet new standards. Make sure
that the wires are connected correctly.
Others
•Adjust the mounting of the D5A until the stroke of the pin plunger
and top plunger is aligned with the stroke of the operating body.
Special attention should be paid to the ceramic pushbutton unit. It
might be damaged 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 displacement
is detected.
•When a limit switch type (D5A-8 @@@, D5A-9 @@@) 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 hardness
(Hv) of a bevel plunger is 2,000 or over, for which it is
recommended 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, provided
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 Operating
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.
