ELECTRONIC SOUNDERS
Loud sounders that may be powered with a voltage of anywhere from 3.0 to 20VDC. Output minimum 95db at
minimum voltage; 105db at 20 volts. Sound frequency is 2.8Khz µ0.5Khz. Typical current draw is 6mA @ 6V DC;
10mA at max. voltage. ABS case meets UL94HB, lead wires are UL listed materials. No other circuitry is needed,
just DC voltage. Mounting ears are on centers of 50mm, case diameter is 42mm O.D.. Available with continuous
tone, on/off tone and with hi/lo dual tone.

This series of single
tone, magnetic buzzers
provides a minimum
sound pressure (at
rated voltages) of
75db. Small and com-
pact, with pigtail leads
for connections. No
moving contacts to pro-
duce arcing, no RF
noise. Low current
requirements* and very
economical. Maximum
width and length are:
0.630” and 1.30”
An electronic audio signal that has applications in electronic instruments, alarms, autos, detectors, and any other application where a rich sound and low
current consumption is required. Wide operating voltage range in continuous tone and intermittent tone models. Available in DC only and AC/DC models.
