RS PRO 85 dB Panel Mount Slow Pulse Internal 42 mm Buzzer 60 V ac/dc Min 250V ac/dc Max

The buzzers operate between 60 V DC and 250 V DC, while needing only a 15 mA supply current. This means they're less likely to malfunction when connected to higher-voltage appliances. They produce a slow pulsing 85 dB tone which is easily heard without being shrill. Measuring in at only 42.5 mm in diameter, the panel mount units are simple to install. FASTON terminals mean wires can be crimped on without the need to solder.

As part of our RS PRO range, these internal buzzers have been thoroughly tested for performance and reliability. They're well-suited for warning devices and alarms in environments with high background noise, such as factories.
