These internal piezo buzzers are ideal for use with a range of industrial equipment. They're part of our trusted RS PRO range and can operate between 60 V AC/DC and 250 V AC/DC. They conveniently combine a high-voltage range with a continuous, loud sound.

These buzzer components can function between -30°C to +85°C and only need a 15 mA supply current. Piezo buzzers don't use magnets or coils to create sound, so they won't impact on surrounding circuitry. This makes them unlikely to malfunction when connected to higher-voltage, heavy-duty equipment. They can be clearly heard even in noisy environments thanks to their continuous 85 dB tone.

These buzzers have been stringently tested and conform to ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 electrostatic control standards. Thanks to their compact, durable structure and loud volume, they're often used as sounders on industrial machinery.
