Mechanical Buzzer (with Wire) Key benefits Compact footprint fits tight spaces: measures 23 x 17 x 15 mm for easy integration into small enclosures. Simple poweronly operation: builtin oscillator means the buzzer sounds when given a DC supply, removing the need for an external driver circuit. Clear, loud alarm: typical output exceeds 85 dB so alerts remain audible in noisy environments. Durable and reliable: molded ABS housing offers long service life under normal operating conditions. Easy wiring and installation: two standard wires, red and black, connect directly to controllers or power supplies; screwmounted design secures quickly to device housings. What makes it useful Reduces component count and wiring complexity by combining oscillator and transducer in one active unit. Small size and standardized wires make it compatible with a wide range of microcontrollers and circuit boards, speeding prototyping and production. sound level and defined operating frequency help ensure audible alerts for warnings, status signals, and confirmations. Typical applications Security and alarm panels for clear audible notifications. Industrial and vending equipment for status alerts and fault indications. Electronic projects, development boards, and microcontroller prototypes that need a compact, plugandplay alert device.
