M2BJ-B
Precautions
Application Precautions
When power is supplied, there is an inrush current of up to 1 A. Con-
firm 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-jjj-D).
Wiring
Perform soldering promptly and correctly at 30 W within 5 seconds
or at a temperature of 240°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 pat-
tern burnout, loop the wire through the terminal hole before solder-
ing.
In order to fit the terminal holes, use lead wires with a nominal cross-
sectional area of 0.25 mm
Operating Environment
Do not use the Buzzer in environments where foreign substances
may enter the sound outlet. Otherwise, the Buzzer may not sound.
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.
