1. Buzzers

1.1. Standard series

Since 1977, Sonitron has been investing in research and development, optimising his standard series, which are used today under the most extreme and difficult environmental circumstances, by clients such as the Nato, Airbus, Volvo Penta, Dr?ger, Knogo, Stanley Door Systems,...

During the last 25 years the standard series have proved to be the prime alarm giving your equipment an added value. Several thousands of clients all over the world have chosen the reliability and the excellent quality of piezo ceramic buzzers of Sonitron.

The range has recently expanded with 4 new models producing over 100 dB(A) at 1 meter as a single tone, intermittent, sweep and warbler.

The housing of the standard series is now available with a square mountable flange.

Nut mounted with two wire connections

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 (SC 0715 BL at 0.7V) and very low current consumption

(SP27 = 4,8 mA at 9V).S T A N D A R D B U Z Z E R S

ABS (UL rating: 94 HB)

Standard colour of case Grey (except the SP27 which is black)

Terminal material Tinned brass for both pin terminals and fast-on terminals Supply voltage The standard buzzers are not damaged by reverse voltage connection (except the SP27 types).

Mounting

PC-board: by soldering the terminals. Front panel mounting:the buzzers can be mounted in panels up to 14 mm thickness (SP27 max. 7 mm). They are locked with a locking pin

(diameter 1mm) and secured to the panel with a plastic nut. Foresee a hole of diameter 32 mm (1.14"). Maximum torque on plastic nut: 6 Nm The step of the thread is 1.5 mm

1.1.6. SELECTION GUIDE

The selection of an acoustic signal can be complex. That is the reason why we present below our standard models with their most appropriate application.SC 235 A

General purpose buzzer with medium sound output for soft alarm in industrial and military applications where a high reliability is requested. These buzzers can be used in a wide supply voltage range.

SC 235 B

General purpose buzzer with high sound output for low power consumption. Ideally

suitable for alarm and industrial sound signals. These models combine high performances and great reliability. The SC 235 B is considered today as the most popular type.SW 535 B A warbling or cricket tone with a special sound effect for warning and alerting signalling devices. These buzzers are also used as a warning device with discrimination against the existing background noise.

SP27

Small size buzzer to be used in applications where space is limited. (Max. supply voltage is 9 Vdc). See also information in addendum.

SUM 516 A1/A5

A universal buzzer type with a selection of three functions: continuous, intermittent or stop. High sound output for low power consumption and low supply voltages. This type can be used for multiple applications where a soft signal is required and a high reliability is a must.

SULM 516 B5

A universal buzzer with a selection mode of different functions: continuous, intermittent or stop. High sound output at very low power consumption. It can be used in all alarm and warning signals where performance, power consumption and size are important. The SULI and the SUC models are simplified versions of the SULM 516 B5 that can be used when mode control is not required.

SC 0715 BL

Special loud buzzer that already functions at very low voltage (0.7 Vdc), going up to 12Vdc, producing 98 dB(A) at 1m. Wide range of applications, including battery powered alarms.

SC 515 C Extreme loud buzzers for multiple applications requiring a highly penetrating sound. The SCI 515 C interrupts the sound, creating more attention.

SW 515 C Extreme loud buzzer with warbler or sweep tones. These buzzers produce a very aggressive sound. They are perfect alarm bells and warning devices for all kinds of applications.
