BZRP2418 is a low current
buzzer so that it can also operate with low current power sources such
as solar panels and coin batteries.
Polarity is marked with + and - signs at
the bottom of the buzzer near each contact. The + contact must be
connected to the positive side of your power source and the - contact
must be connected to the negative side of your power source.
High frequency sound travels longer
distances. |
We can custom produce this buzzer with contact
wires at any length instead of the pins.
