nv/sa Excellence in physical acoustics SC0715BL STANDARD BUZZER Pagina 1 van 6 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.

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 Thermal Shock Humidity Salt Spray Shock Vibration Thermal strength Method MIL STD202 107 103 101 213 B 201 A 211 Test conditions A B A H none 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.
