RS PRO 85dB Panel Mount Continuous Internal Buzzer, 28 (Dia.) x 24.4mm, 3V dc Min, 28V dc Max

Part of our proven RS PRO range, these continuous internal buzzers are a versatile choice for alarms and warning systems. They're small in size and deliver low power consumption with a wide voltage range and crisp sound.

These buzzers draw a 6 mA supply current and can operate between 3 V DC to 28 V DC. This means they're energy-efficient and compatible with most consumer appliances, such as telephones and timers. They emit a continuous 85 dB tone that can be clearly heard over background noise. This all comes in a compact, panel-mount unit that's simple to install. Flying leads means the wires can be easily connected to a circuit board.

Thorough testing has been performed on these buzzers to ensure they meet RS PRO standards. They also conform to ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 standards for protection from harmful electrostatic discharge. They're commonly be found in alarm systems and automotive equipment.
