Set up the sound system in your installations with this WERMA electronic piezo buzzer. It serves as a status indicator by releasing continuous, slow pulse buzzes at set times. This device is encased in PC/ABS (polycarbonate/acrylonitrile butadiene styrene) thermoplastic material which offers heat resistance up to +60°C, so you can rely on it in demanding environments. With a maximum sound output of up to 90dB, you can be sure this device will be heard in your workplace.

• In-built panels eliminate the need for wiring or soldering and make for easy mounting
• Compact 43 x 38mm dimension for easy handling and storage
• IP30 (ingress protection) rating means it’ll resist intrusion from tools up to 2.5mm in diameter, preventing scratches and damage
• At least 5,000 hours of acoustic lifespan enables long-term reliable output of sound waves

• Alarm systems
• Automobile alert
• Assembly plants

The core components of this piezo buzzer are the piezoelectric ceramic and a metal plate held together by a strong adhesive. The piezoelectric element is flexible and allows a current of up to 230V AC to pass through it which causes it to shrink and expand. The resulting vibration produces sound waves.
