Passive 2wire electronic buzzer for DC 130V applications. Designed for audible alerts and alarms, this passive buzzer is commonly used in 12V systems and produces an 85dB sound output. The black housing offers a discreet installation option for a wide range of equipment. Key benefits Wide input range: Operates from DC 130V, suitable for lowvoltage electronics and typical 12V systems. Clear audible alert: Rated at 85dB, provides a noticeable alarm signal for attention and status indication. Simple installation: Twowire design reduces wiring complexity for quick connection to drivers or control circuits. Passive operation: Requires an external driving signal or PWM from a controller, allowing flexible tone control and integration with existing systems. Versatile fit: Black housing blends into control panels and enclosures without drawing attention. Features and specifications Function: Passive electronic buzzer for alarm and alert tones Voltage: DC 130V (commonly used at 12V) Wiring: 2wire connection Sound level: 85dB Color: Black Compatibility and use Compatible with microcontrollers, alarm panels, timer circuits, and devices that can provide an appropriate driving signal to a passive buzzer. Suitable for integration into systems that operate within the DC 130V range. Practical application examples Security and alarm systems: Add an audible alert to a door alarm, motion detector, or access control panel powered by a 12V supply. Automotive and vehicle equipment: Use as a warning or status buzzer for 12V dashboard indicators, reverse sensors, or aftermarket accessories. DIY electronics and control projects: Connect to microcontroller PWM outputs to generate custom tones and audible feedback for prototypes and hobby builds. Installation notes As a passive buzzer, a driving signal is required to produce sound. Connect to a suitable driver, microcontroller PWM pin, or alarm output that matches the device voltage range. Confirm the driving method and duty cycle to achieve the desired tone and volume. This passive 2wire buzzer offers a straightforward solution for audible alerts across a variety of DCpowered systems while remaining flexible for programmable tone generation.
