Safety Precautions
Refer to Safety Precautions for All Pushbutton Switches.
Application Precautions
•When power is supplied, there is an inrush current of up to 1 A.
Confirm that this will not adversely affect operation or damage any
devices before using the M2BJ in application. There is no inrush
current with DC-only models (M2BJ-@@@-D).
•With models that can use both AC and DC, residual energy in the
internal capacitor may cause residual sound.
Wiring
•Perform soldering promptly and correctly at a temperature of 350°C
within 3 seconds.Wait for one minute after soldering before exerting
any external force on the solder.
•If flux is required, use non-corrosive rosin liquid. Ensure that the flux
does not penetrate the inside of the case.
•In order to improve the reliability of the soldering and to prevent
pattern burnout, loop the wire through the terminal hole before
soldering.
•In order to fit the terminal holes, use lead wires with a nominal cross
sectional area of 0.25 mm2 max.
Operating Environment
•Do not use the Buzzer in environments where foreign substances
may enter the sound outlet. Otherwise, the Buzzer may not sound.
Volume Adjustment Mechanism (M2BJ-BH Only)
•Adjust the volume by turning the control knob on the face of the
Buzzer using a screwdriver. Turn to the right to increase the volume
and turn to the left to decrease the volume.
•Turn the control knob with a torque of 0.98 to 2.94 mN·m.
Short-circuiting Jumper (M2BJ-BTH)
•The Buzzer sounds continuously or intermittently depending on
how the short-circuiting bracket is attached to the case guide.
When the bracket is attached with the triangle on it facing direction
A (PC board side), the Buzzer sounds intermittently.
•To produce continuous sounds, attach the bracket to the case
guide so that the triangle on the bracket faces direction B.
•The bracket is set in direction A when ship the product. If the
bracket becomes lost, contact your OMRON representative. The
model number to order is M2BJ-BTH.

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 Prod-
uct 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 equip-
ment, and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or prop-
erty. Please know and observe all prohibitions of use applicable to this Prod-
uct.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT
ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO
ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-
ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
OVERALL EQUIPMENT OR SYSTEM.
2. Programmable Products. Omron Companies shall not be responsible for the
user’s programming of a programmable Product, or any consequence thereof.
3. Performance Data. Data presented in Omron Company websites, catalogs
and other materials is provided as a guide for the user in determining suitabil-
ity and does not constitute a warranty. It may represent the result of Omron’s
test conditions, and the user must correlate it to actual application require-
ments. Actual performance is subject to the Omron’s Warranty and Limitations
of Liability.
4. Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our prac-
tice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifica-
tions of the Product may be changed without any notice. When in doubt, spe-
cial part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Omron’s representative at any time
to confirm actual specifications of purchased Product.
5. Errors and Omissions. Information presented by Omron Companies has been
checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors or omissions.
