RS PRO 85dB Screw Mount Slow Pulse Internal Buzzer, 42.5 (Dia.) x 33mm, 6V ac/dc Min, 28V ac/dc Max

Designed to be versatile, these internal buzzers operate at a wide voltage range and deliver crisp sound from a compact package. They're part of our stringently tested RS PRO series.

The buzzers draw a 23 mA current which makes them more reliable than lower current buzzers, and they can function between 6 V dc to 28 V dc. They're suitable for use in many areas, including most consumer appliances such as computers and microwaves. They produce a slow-pulsing 85 dB tone that can be clearly heard from a considerable distance. Moreover, they have a lower impact on surrounding circuitry than magnetic buzzers. They are also screw-mounted which makes installation as simple as tightening a screw.

Rigorous testing has ensured these buzzers meet international standards. They meet the ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 standards, which means they've been handled and packaged in a way that protects them from harmful electrostatic discharge. Piezo buzzers can be used in car equipment, doorbells and fire alarms, among other applications.
