Ordering Information

*1.High-sound models incorporate an LED, which lights when the Buzzer sounds. *2.Refer to “Short-circuiting Jumper (M2BJ-BTH)” on page 5 for the insert direction of the jumper. External Signal Selection Model (M2BJ-BH24D-DA)

• An external signal selection model is also available. With this model, it is possible to switch between continuous and intermittent sound using an external signal instead of the jumper.

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 APPLICA TION 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 PRO DUCT IS PROP- ERL Y 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.
