RS PRO Piezo Buzzer Component, 6.5 mm Height, Through Hole, 75 dB, Continuous Internal, 3V - 20V DC, 237-956

The RS PRO 237-956 Piezo Buzzer Component is a through-hole, PCB-mountable electronic sounder designed to deliver continuous tone alerts in control panels, instrumentation, and embedded devices. Built for seamless integration into electronic assemblies, this buzzer features a high sound output of 75 dB, ensuring reliable audible signaling in industrial and commercial environments.

With an operating voltage range from 3V DC to 20V DC, the buzzer accommodates a wide variety of power supply configurations, making it suitable for both low-power and standard circuit requirements. Its internal drive mechanism supports continuous tone output, making it ideal for applications demanding persistent audio alerts or notifications.

The component is housed in a circular case with a diameter of 23.3 mm and a compact height of 6.5 mm, allowing installation in space-constrained electronics, control boards, and device enclosures. The through-hole mounting design ensures robust mechanical stability and easy soldering during PCB fabrication and repair.

Engineered for reliability, the buzzer operates efficiently across a wide temperature range from -30°C up to 85°C, making it suitable for both indoor and harsher environmental conditions found in manufacturing, laboratory, and automation applications. The device is RoHS-compliant, guaranteeing that it meets international environmental safety standards.

Typical applications include industrial control panels, alarm systems, sensor warnings, embedded microcontroller boards, and any instrumentation requiring distinct sound notification. The buzzer's supply current is rated at 13 mA, which enables energy-efficient operation without imposing excessive demand on DC power supplies.

Performance specifications include a maximum frequency of 3.7 kHz and a minimum frequency of 2700 Hz, accommodating clear, audible tones that are noticeable even amidst ambient noise. The continuous tone type further enhances usability in long-duration alert scenarios. Manufactured with proven RS PRO reliability, the 237-956 buzzer is the solution of choice for professional-grade signaling in electronics, automation, and laboratory equipment.
