PUI Audio 85 dBA Panel Mount Continuous Buzzer 3 V dc Min 15V dc Max

PUI Audio Buzzer, 85dBA Sound Level, 3V to 15V Supply Voltage - LAI-2540-PG-WP

This buzzer is a Compact audio signalling device designed for panel installation in industrial and electronic control environments. It provides a continuous audible alert suitable for automation and electrical systems, operating across a broad supply voltage range to accommodate varied low-voltage designs.

Features and Benefits:

• High frequency output for clear signalling at 3700 to 4300 Hz
  Continuous tone operation for persistent alarm indication
  Wide supply range supports 3 to 15V systems
  Low supply current reduces power draw at 20 mA
  Rated sound pressure of 85 dBA for effective audible reach
  Temperature tolerance supports -20 °C to 70 °C environments

Applications

• Suitable for industrial alarm panels requiring Compact indicators
  Ideal for control cabinets in automation systems
  Used with low-voltage electronics as an audible status cue
  Can be used for safety warning signals in machinery panels
  Suitable for retrofit as a PCB replacement panel buzzer in equipment

What mounting method does it use for panel integration?

It is designed for panel-mount installation, enabling direct mounting into instrument and control panels.

How does it perform in moisture-prone installations?

The unit is specified as waterproof for use where ingress protection is needed in panel-mounted signalling.

What tone character should installers expect during operation?

It emits a continuous tone, providing an uninterrupted audible alert rather than intermittent beeps.

Are there regulatory or material restrictions relevant to procurement?

The device meets RoHS requirements, ensuring restricted-substance compliance in electronic assemblies.
