D5A
High-precision Switch for Detecting Micron-unit
Displacement
•
Ideal for detecting and measuring wear of cutting
tools or for original point of work.
•
Ceramic plungers on M5, M8, and slim models for
superior abrasion resistance and resistance to
temperature changes.
•
Direct input possible to microprocessors and
programmable controllers.
•
A version with screw-type cable connector available
for easy installation and maintenance.

Origin can be set to a desired
position and the origin position
can be controlled using the D5A.
The D5A can be mounted on a jig
used for checking deviation to in-
spect its coaxiality.
Set the D5A on the turret index-
ing position to check if the turret
is engaged properly at the spec-
ified position.

Safety Precautions
Refer to
Safety Precautions for All Limit Switches.
Precautions for 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 R20 mm.
•
The 40-mm portion of the fiber cable on the connector end as
shown below must not be bent.
40 mm min.
•
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.

Consideration of polarity is not required.
•
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.
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.

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.

Note: The lead wire colors of the D5A have been changed in compliance with

[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.
