Our Smallest Self Contained <strong>Electronic</strong> Alert<br />
This is a self contained (no driver circuitry needed) electronic tone alert device. Simply connect 8VDC up to 16VDC to the correct polarity and this item<br />
emits a loud 2400Hz tone. This alert is only .47”Dia. x .36”tall. Made by American Audio part# SEB122. Sound output @ 10cm is 85dB. Only requires<br />
30mA current. Brand new and very unusual due to the tiny size but loud output.<br />

3 Lead Piezo Disk<br />
Murata 7SB-34R7 high output selfdriven<br />
(with feedback electrode) piezo<br />
disk requires only 1 transistor to drive<br />
it. Resonant frequency is 3.1 KHZ, resonant<br />
resistance is ≥ 160, capacitance is 24000pf. size<br />
is 34.7mm. These are brand new and perfect for making<br />
a clear penetrating loud alarm sound. They create<br />
no electronic noise and require 1/10 the power of a<br />
comparable electromechanical buzzer. We even include<br />
a simple 1 transistor schematic that shows how<br />
to use 1 2N3904 transistor and several resistors and<br />
several capacitors to drive this piezo. Brand new prime!<br />
