Moflash AE20M Series Panel Mount Buzzer, 230 V, 95dB at 1 m, IP55, AC, Single-Tone

This compact piezo buzzer from Moflash is ideal as a warning signal for industrial and commercial applications. It works by using a piezo crystal to push a diaphragm, generating a pressure wave that produces sound. As the buzzer consumes just 25mA of current, it's an energy-efficient choice. You can choose between a continuous or a pulsing tone, depending on your needs.

• Base made of ABS (acrylonitrile butadiene styrene) plastic for resistance to impact and corrosion
• Produces 90dB (decibels) of sound for a highly audible warning signal
• IP55 (ingress protection) rating for resistance to dust and low-pressure water jets
• Wide operating temperature range of -25°C to +55°C for use in demanding conditions
• Compact diameter of 43mm for use in panels with limited space

• Pest deterrent devices
• Automobile devices
• Production plant warning systems

This buzzer produces sound waves from the oscillation of the piezoelectric diaphragm via a sound emission hole, meaning it's not sealed from the environment. This means you should be sure not to close the hole and remove obstacles within 15mm on the front side of the casing.
