AC Continuous Buzzer
WORKING PRINCIPLE: The 230V AC continuous buzzer operates using an internal electromagnetic or piezoelectric sound generating mechanism with a built-in oscillating circuit. When AC voltage is applied across the terminals, the internal oscillator drives the vibrating element at a fixed frequency, producing a loud continuous sound. Because the oscillation circuit is built inside the device, it automatically generates the tone whenever power is supplied.
MODULE STRUCTURE: The buzzer consists of a compact circular housing that contains the sound-generating element, an internal oscillation circuit, and a protective casing. The outer body is designed to enhance sound resonance while protecting the internal components. The device includes a flange mounting structure that allows secure installation on panels or enclosures.
PIN CONFIGURATION: The buzzer has two wire leads for electrical connection: Live (AC Input) – Connects to the AC supply line, Neutral (AC Input) – Connects to the neutral line of the AC supply
INTERFACE CONNECTION: The buzzer is directly connected to a 230V AC power source or through switching devices such as relays, control circuits, or alarm controllers. When power is applied, the buzzer immediately produces a continuous sound.
OUTPUT FUNCTION: The device produces a loud continuous beep that can reach high sound levels.
OPERATING VOLTAGE: Operating Voltage: 230V AC
SIGNAL CONDITIONING: The buzzer contains an internal oscillation circuit that generates the required sound frequency automatically, so no external signal generator is required.
CHARACTERISTICS: Minimum Sound Level: Approximately 100 dB, Oscillation Frequency: 4 kHz ± 500 Hz, Maximum Current Consumption: 20 mA, Tone Type: Loud continuous sound
Mounting Type: Flange mount, Operating Temperature Range: 20°C to 50°C.DIMENSION: Wire Length: Approximately 120 mm (2 wires), Height: 24.5 mm, Diameter: 38.5 mm.
APPLICATION SCOPE: 230V AC buzzers are commonly used in electrical alarm systems, industrial control panels, security warning systems, household alert devices, electronic metronomes, and educational electronic experiments where a loud audible signal is required.
