Electromagnetic Active Buzzer 5V (XHXDZ-TMB12A05)

Electromagnetic Active Buzzer 5V (XHXDZ-TMB12A05) — Overview

The Electromagnetic Active Buzzer (XHXDZ-TMB12A05) is a compact, reliable audio signaling device designed for alarms, automation and electronics projects. As an active buzzer, it includes a built-in oscillation circuit, so it requires only a DC supply to produce a consistent audible tone without an external driver.

Key Advantages

• Ready-to-use active buzzer with internal oscillator — simply apply 5V DC to operate.
• Clear, continuous tone optimized for human hearing.
• Low power consumption and compact electromagnetic design for space-limited applications.
• Standard 2-pin interface for quick connection to power supplies and controllers.

Specifications

• Model: XHXDZ-TMB12A05
• Type: Electromagnetic Active Buzzer
• Operating Voltage: 5V DC (typical)
• Interface: 2-pin
• Output: Clear, continuous tone when powered
• Power: Low consumption (electromagnetic design)

Applications

This 5V active buzzer is suitable for a wide range of projects and systems, including:

• Security alarms and warning systems
• Timers and reminder devices
• Home and industrial automation systems
• Consumer electronics and embedded systems
• Robotics, DIY kits and maker projects

Integration and Wiring

The XHXDZ-TMB12A05 uses a simple 2-pin connector. Integration is straightforward:

• Connect the positive 5V DC supply to the V+ pin.
• Connect the ground to the GND pin.
• No PWM or external signal generator is required — the internal oscillator produces the tone when powered.

It is compatible with microcontroller platforms such as Arduino, Raspberry Pi and ESP32. For driven tone patterns, control power to the buzzer from a GPIO pin through an appropriate transistor or driver circuit; check your controllers pin current limits before direct connection.

Why Choose This Active Buzzer

• Plug-and-play operation: built-in oscillator removes the need for additional circuitry.
• Versatile: works in both hobbyist and professional embedded projects.
• Reliable audio feedback for critical alerts and user notifications.
