Sonitron 86 dB Panel Mount Continuous Internal 26 mm Piezo Buzzer Component 140 mm 5 V dc Min 35V dc Max SCI535B1

Sonitron SCI535B1 is a high-performance panel mount piezo buzzer component designed for robust electronic applications requiring reliable audible signals. It operates with a minimum supply voltage of 5 V dc and a maximum of 35 V dc, providing a continuous internal drive that generates a loud 86 dB sound level. The buzzer features a compact 36.5 mm diameter and 26 mm height, ensuring it fits efficiently into control panels or equipment housings.

With a length of 140 mm and robust durability, the device supports a wide temperature operational range from -40°C to 85°C, making it suitable for industrial, military, and harsh environmental uses. This buzzer complies with MIL STD202, NATO standards, and has an IP67 ingress protection rating along with ABS UL 94HB fire retardance, ensuring long-term reliability and safety in electrical systems.

The buzzer produces a continuous tone ranging in frequency from 2975 Hz to 4.025 kHz, providing clear and effective warning or alert signals. It draws a modest 12.2 mA current, allowing energy-efficient operation in power-sensitive systems. The panel hole mount with 6.3 x 0.8 mm faston connectors facilitates secure and straightforward electrical connection.

Ideal for industrial automation, control panels, safety alarms, and electronic signaling applications, the Sonitron SCI535B1 combines precise acoustic performance with rugged design. Its internal drive electronics allow simple integration within DC-operated circuits, reducing the need for additional control hardware.
