STANDARD BUZZER
The standard series are based on the highest piezo
technology and are considered to be the most robust series
for industrial applications.
The standard buzzers use a bent edge membrane, which is
fixed and glued into the housing, guaranteeing shock, dust
and waterproof operations. The different standard models
cover a very wide range of applications, offering functions
such as continuous, intermittent, sweep and warbler, with a
sound output over 100 dB(A).
All standard products are manufactured to meet various mounting methods, such as PCB or
panel mounting and are therefore equipped with either pins or fast-on terminals. The standard
series include military models, extra loud types, as well as models operating at very low voltage
consumption
The SC 0715 BL is a special loud buzzer that already functions at very low voltage (0.7 Vdc),
going up to 12 Vdc, producing 98 dB(A) at 1 meter. Wide range of applications, including
battery powered alarms.
ADVANTAGES
• extremely high sound pressure level with a very clear and penetrating sound output
• solid state shock proof buzzer. Dust and waterproof, rated to IP67
• PCB and panel mounting; pin or fast-on terminals

• low power consumption
• wide operating supply range
• wide temperature range
APPLICATIONS
• alarms
• industrial enunciator equipment
• monitoring and test equipment
• medical equipment
• military equipment
• trucks and automobiles, boats and airplanes
• signalling & process control equipment
• fire detectors etc.
• etc.

MILITARY MODELS
All standard models can be delivered in a military version. All military models have flame
retardant ABS housings in olive green and fast-on terminals.
The military models guarantee a quality superior to the classic models. On top of the standard
specifications, the military models are tested as follows:
Test Method MIL STD202 Test conditions
Thermal Shock 107 A
Humidity 103 B
Salt Spray 101 A
Shock 213 B H
Vibration 201 A none
Thermal strength 211 A (10 Lbs, 2 cycles)
MODELS ON REQUEST
The standard buzzers can be modified upon request in order to deliver a product, meeting the
requirements of the customer's application.
• Upon special request all standard models are also available in GREY, BLACK or GREEN
(khaki). Please add GREY, BLACK or GREEN to the part number if the required colour is
different from the one specified as standard.
• For applications under aggressive humid conditions, models containing a piezo element
covered with a protective coating are available. Add ACR to the part number.
• The protective coating gives a complementary assurance against smog; all standard
models are perfectly waterproof (IP67) without the mentioned coating.
• Different pin terminal lengths, straight or bent can be custom manufactured.
• The frequency, indicated in the present catalogue, has an accuracy of +/- 15%. Standard
buzzers with an improved frequency accuracy (up to +/- 2%) are available upon special
customer request.
