VERSATILE SOUNDERS HAVE VOLUME BAFFLE FOR REDUCED INVENTORY AND INCREASED VERSATILITY
30 September 2003 - Switchtec Electronics Ltd

Sonartone sounders from Switchtec now have a volume control baffle as standard, making them useable in a wider range of applications. The baffle is adjusted simply in much the same way as a standard telephone sounder baffle, enabling the units to be used in applications where a lower level, or adjustable audible warning signal is required.

The sounders are designed to give an audible warning that is higher than the prevailing ambient noise level, thus providing an audible signal for safety or indication purposes. Such applications include safety, security, machine building, process plant, vehicles/automotive, marine and so on.

Aimed at Panel builders and OEMs, the solid-state sounders consume low power - generally in the region of 3 to 18mA at the rated operating voltage. The devices will operate over a wide temperature range of -30°C to +60°C, and suitable for use in hostile environments, are completely sealed.

For long life and reliability, the sounders have no moving parts, and as such also generate no RF noise as there is no arching or electrical interference generated. An overvoltage of up to 15% above rated voltage will not damage the sounder and accidental reverse voltage up to 28Vdc for less than one minute will similarly not result in damage.

Measuring just 43mm in diameter, the devices produce a mighty 80 -95dB at 1m, at a frequency of 2.9kHz. Different tones are available covering constant, pulsating, slow pulsating, dual constant/pulsating, and dual constant/slow pulse.

Exhibiting versatility, AC or DC models are available up to 250Vac and 28Vdc. Connections are via plated brass push on terminals, which also have screws fitted for alternative fixing if required.

The versatile Sonartone sounders range from Switchtec is very competitively priced, and offers a wide range of units for many applications.
