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 mm 2 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.
