Product Details

Sound Pressure and Frequency

The B2PB buzzers produce sound at a pressure level of 98 ±8 dB, measured at a distance of 0.1 meters, and operate at a sound frequency of approximately 2.5 kHz. This ensures the sound is not only loud but also falls within an optimal frequency range for effective alerting.

Mounting and Installation

Designed for ease of installation, these buzzers can be mounted in panels with hole sizes of Ø22/25 mm and can accommodate panel thicknesses up to 4 mm. The unit’s compact size and the included nut ensure secure and stable attachment to the mounting surface.

Operational Indicators and Power Consumption

The B2PB series features an operation indicator LED (green for B2PB-B1D and red for B2PB-B1D-R) that provides clear visibility of the buzzer's status. The buzzers are energy-efficient, with a maximum power consumption of 0.6 W and current consumption limited to 25 mA, making them suitable for various power-sensitive applications.

Durability and Environmental Resistance

These buzzers are built to withstand challenging conditions, with an IP65-rated front face that offers protection against dust and water jets. They can operate within a temperature range of -15 to 55°C and a humidity range of 35 to 85 %RH without risk of freezing or condensation, ensuring reliability in various environments.
