CSM_A7D_A7DP_DS_E_3_1
Ultra-small, Low-cost, Push-operated
Switches
• All-in-one design means fewer parts are required. This product
delivers high reliability at a low cost.
• Uses long-lasting resin springs to achieve a long mechanical
durability expectancy of 30,000 operations.
• Models with stoppers for restricting the setting range are available.
• The series includes a complete range of pen-push models that
prevent accidental operation.

Note: 1. The classification diagrams show 4 Switch Units combined with End Caps to create 4-digit displays.
2. The model numbers given above are for 1 Switch Unit.
3. Models with stoppers are also available. Add “[email protected]@” after the “106” or “206” in the model number and specify the display range in the @@. For example, to
specify the range 0 to 6, add “-S06” to the model number (e.g., A7D-106-S06-1).
4. Models with +, - displays are also available. Add “-PM” after the “106” or “206” in the model number (e.g., A7D-106-PM or A7D-106-PM-1).
Accessories (Order Separately)

* The minimum order is for 10 End Caps.
End Caps
End Caps are used on the Switch Units at each end and allow all the Switch Units to be securely mounted to a panel. They come in pairs, one for
the left and one for the right.
Spacers
• Spacers are used for creating extra space or gaps between the Switch Units and have the same dimensions as the Switch Units themselves.
• There are also Spacers with engraved characters or symbols that can be used for indicating units, such as time and length. (Refer to the following
table.) Consult your OMRON representative for details.

factory-assembled sets.
Safety Precautions
Refer to Safety Precautions for All Thumbwheel Switches.
Precautions for Correct Use
Handling
• The molded components of the Switch use polyacetal resin and
PBT resin. It is recommended that alcohol is used to wipe off dirt
and smudges from the molded components. Take care to prevent
the alcohol from getting inside.
• Do not use thinner or other solutions which might damage the resin.
• Terminals can withstand a force of 4.9 N for 10 seconds or more
(the mating strength of the case and seal), and survive bending of
20° without breaking after returning to original position. Do not use
excessive force or apply repetitive external force, however, when
handling terminals. In particular, take care to avoid dropping them
as the terminals might bend or break.
Soldering
• Using a Soldering Iron
Use a 30-W soldering iron at a temperature of 350°C for a maximum
of 3 seconds, and flush as described above.
Do not apply force to the terminals during soldering and for 3 minutes
after soldering is completed. Doing so may result in conduction or
operation failure.
Ensure that soldering flux and alcohol do not penetrate into the Switch
interior
Setting Numbers
Pen-push Type
Press the setting switch with the tip of a ball-point pen. Do not use
pencil point or mechanical pencil point to press the setting switch,
otherwise the lead of the pencil or mechanical pencil may be broken
and A7DP malfunctions may result due to fragments of the broken
lead.
• The setting buttons can withstand 19.6 N for 1 minute, but do not
push the (+) and (-) buttons at the same time.
Screw-mounting Models
Tighten mounting screws to a torque between 0.2 to 0.24 N·m, using
M2.6 screws. Use plain washers or spring washers together with the
screws.

SUITABILITY FOR USE
OMRON shall not be responsible for conformity with any standards, codes, or regulations that apply to the combination of products in the customer's
application or use of the products.
At the customer's request, OMRON will provide applicable third party certification documents identifying ratings and limitations of use that apply to the
products. This information by itself is not sufficient for a complete determination of the suitability of the products in combination with the end product,
machine, system, or other application or use.
The following are some examples of applications for which particular attention must be given. This is not intended to be an exhaustive list of all possible
uses of the products, nor is it intended to imply that the uses listed may be suitable for the products:
 Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this catalog.
 Nuclear energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles,
safety equipment, and installations subject to separate industry or government regulations.
 Systems, machines, and equipment that could present a risk to life or property.
Please know and observe all prohibitions of use applicable to the products.
NEVER USE THE PRODUCTS FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE
SYSTEM AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT THE OMRON PRODUCTS ARE PROPERLY RATED AND
INSTALLED FOR THE INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.
PROGRAMMABLE PRODUCTS
OMRON shall not be responsible for the user's programming of a programmable product, or any consequence thereof.
Disclaimers
CHANGE IN SPECIFICATIONS
Product specifications and accessories may be changed at any time based on improvements and other reasons.
It is our practice to change model numbers when published ratings or features are changed, or when significant construction changes are made.
However, some specifications of the products may be changed without any notice. When in doubt, special model numbers may be assigned to fix or
establish key specifications for your application on your request. Please consult with your OMRON representative at any time to confirm actual
specifications of purchased products.
DIMENSIONS AND WEIGHTS
Dimensions and weights are nominal and are not to be used for manufacturing purposes, even when tolerances are shown.
PERFORMANCE DATA
Performance data given in this catalog is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the
result of OMRON’s test conditions, and the users must correlate it to actual application requirements. Actual performance is subject to the OMRON
Warranty and Limitations of Liability.
