Need to connect a buzzer to industrial equipment? These internal piezo buzzers from our RS PRO range can operate between 60 V AC/DC and 250 V AC/DC. They combine this high-voltage range with a loud and continuous sound.

These buzzer components need only an 18 mA supply current and can function between -30°C to +85°C. Because piezo buzzers don't use magnets or coils to create sound, they won't affect surrounding circuitry. This makes them versatile and less likely to malfunction when connected to higher-voltage, heavy-duty equipment. They produce a continuous 87 dB tone that can be clearly heard – even in noisy environments.

The buzzers have been thoroughly tested and conform to the ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 electrostatic control standards. Thanks to their compact yet sturdy construction and loud volume, they're used in industrial workplaces as sounders on machinery.
