These powerful internal buzzers offer a space-saving design combining a high voltage range and clear sound. With a broad operating temperature range of -30°C to +85°C, they're ideal for manufacturing environments that experience temperature variations.

The buzzers only need a 15 mA supply current and operate between 60 V DC and 250 V DC. This makes them unlikely to malfunction when connected to higher-voltage appliances. Thanks to a slow-pulsing 70 dB tone, they're easily heard without being shrill. The panel-mount units are simple to install, measuring in at only 42.5 mm in diameter. They're fitted with FASTON terminals, which mean that wires can be crimped onto them without the need to solder.

These internal buzzers have been thoroughly tested for performance and reliability as part of our RS PRO range. They're typically used in warning devices and alarms in environments such as factories, where there's high background noise.
