Precautions
■ Precautions for Correct Use
Applicable Terminals
Wiring
The following solderless terminals can be used.
(Do not use fork or any other type of terminals, otherwise an
accidental disconnection resulting in a ground fault may result.)
Wiring Procedure
Terminal with insulated grip
1. Loosen the cover mounting screws and remove the cover.
2. Run the wiring through the rubber connector on the cover and
then press-fit the solderless terminals. (The following solderless
terminals are available.)
3. After inserting the solderless terminal into the Switch, tighten the
terminal screws securely.
4. Mount the cover. (Make sure that the rubber connector is securely
pressed into the cover slot.)
5. Tighten the three screws evenly. (The optimum tightening torque
for each screw is 0.49 to 0.59 N·m.)

Others
• Do not use the Limit Switch outdoors, otherwise the Limit Switch
will be damaged by rust or ozone.
• The Limit Switch is not suitable in places exposed to the spray of
rainwater, seawater, or oily water. Contact your OMRON
representative if such specifications are required.
• If high-sealing performance is required along with shielded wiring
or conduit wiring, use the D4C or WL.
Using the Switch
Changing the Actuator Mounting
Position
Changing the Head Direction
(D4V-8104Z, D4V-8108Z, D4V-8107Z)
By loosening one screw (black) at a time, the head can be changed
at 90° increments in any of the four directions.
By loosening the Allen-head bolt on the actuator lever, the position of
the actuator can be set anywhere within the 360°.
Loosen the

Operation
• Operate the coil spring and wire spring models between the tip of
the actuator and 1/3 the length of the actuator and parallel to the
direction of operation.
• Handling the bottom of the actuator or excessively pushing in the
tip may lead to bending damage, deformation, malfunction, and
deterioration of service life.
• Contact bouncing, chattering, or telegraphing may occur.
Take steps so that incorrect signals are not detected on the circuit
side if doing so will cause problems with the application.
Note: Telegraphing refers to the phenomenon of the actuator being
used and bouncing back after the operating body has passed,
and moving to the operation point on the opposite side, which
causes the contact to operate.

security or payment in advance. If Buyer fails to make payment or otherwise
comply with these Terms or any related agreement, Omron may (without liability and in addition to other remedies) cancel any unshipped portion of Products sold hereunder and stop any Products in transit until Buyer pays all
amounts, including amounts payable hereunder, whether or not then due,
which are owing to it by Buyer. Buyer shall in any event remain liable for all

except in “break down” situations.
b. Such carrier shall act as the agent of Buyer and delivery to such carrier shall
constitute delivery to Buyer;

ITY OR FITNESS FOR A PARTICULAR PURPOSE OF THE PRODUCTS.
BUYER ACKNOWLEDGES THAT IT ALONE HAS DETERMINED THAT THE
PRODUCTS WILL SUITABLY MEET THE REQUIREMENTS OF THEIR
INTENDED USE. Omron further disclaims all warranties and responsibility of
any type for claims or expenses based on infringement by the Products or otherwise of any intellectual property right. (c) Buyer Remedy. Omron’s sole obligation hereunder shall be, at Omron’s election, to (i) replace (in the form
originally shipped with Buyer responsible for labor charges for removal or
replacement thereof) the non-complying Product, (ii) repair the non-complying
Product, or (iii) repay or credit Buyer an amount equal to the purchase price of
the non-complying Product; provided that in no event shall Omron be responsible for warranty, repair, indemnity or any other claims or expenses regarding
the Products unless Omron’s analysis confirms that the Products were properly handled, stored, installed and maintained and not subject to contamination, abuse, misuse or inappropriate modification. Return of any Products by
Buyer must be approved in writing by Omron before shipment. Omron Companies shall not be liable for the suitability or unsuitability or the results from the

See http://oeweb.omron.com or contact your Omron representative for published information.
Limitation on Liability; Etc. OMRON COMPANIES SHALL NOT BE LIABLE
FOR SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES,
LOSS OF PROFITS OR PRODUCTION OR COMMERCIAL LOSS IN ANY
WAY CONNECTED WITH THE PRODUCTS, WHETHER SUCH CLAIM IS
BASED IN CONTRACT, WARRANTY, NEGLIGENCE OR STRICT LIABILITY.
Further, in no event shall liability of Omron Companies exceed the individual
price of the Product on which liability is asserted.
Indemnities. Buyer shall indemnify and hold harmless Omron Companies and

in any way without the written permission of Omron. Notwithstanding any
charges to Buyer for engineering or tooling, all engineering and tooling shall
remain the exclusive property of Omron. All information and materials supplied
by Omron to Buyer relating to the Products are confidential and proprietary,
and Buyer shall limit distribution thereof to its trusted employees and strictly
prevent disclosure to any third party.
Export Controls. Buyer shall comply with all applicable laws, regulations and
licenses regarding (i) export of products or information; (iii) sale of products to
“forbidden” or other proscribed persons; and (ii) disclosure to non-citizens of

law of the jurisdiction of the home office of the Omron company from which
Buyer is purchasing the Products (without regard to conflict of law principles). (d) Amendment. These Terms constitute the entire agreement between
Buyer and Omron relating to the Products, and no provision may be changed
or waived unless in writing signed by the parties. (e) Severability. If any provision hereof is rendered ineffective or invalid, such provision shall not invalidate
any other provision. (f) Setoff. Buyer shall have no right to set off any amounts
against the amount owing in respect of this invoice. (g) Definitions. As used
herein, “including” means “including without limitation”; and “Omron Companies” (or similar words) mean Omron Corporation and any direct or indirect
subsidiary or affiliate thereof.
Certain Precautions on Specifications and Use
1. Suitability of Use. Omron Companies shall not be responsible for conformity
with any standards, codes or regulations which apply to the combination of the
Product in the Buyer’s application or use of the Product. At Buyer’s request,
Omron will provide applicable third party certification documents identifying
ratings and limitations of use which apply to the Product. This information by
itself is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application
or use. Buyer shall be solely responsible for determining appropriateness of
the particular Product with respect to Buyer’s application, product or system.
Buyer shall take application responsibility in all cases but the following is a
non-exhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Use in consumer products or any use in significant quantities.
(iii) 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.
(iv) Systems, machines and equipment that could present a risk to life or property. Please know and observe all prohibitions of use applicable to this Product.
