PS-733WDY-SQ

Overview

The PS-733WDY-SQ is a piezo buzzer with an integrated yellow LED indicator, manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 5V to 15V and draws 200mA. The device produces a siren sound type at an oscillation frequency between 2.5kHz and 4.5kHz, achieving a sound pressure level of 85dB at 300cm. Designed for surface mount installation, it features wire leads and measures 32mm x 46mm x 16mm.

Feature Summary

• Integrates a piezo transducer with a yellow LED visual indicator
• Generates a high-intensity siren audio signal
• Supports surface mount technology with wire lead termination

Applications

• Industrial machinery status alarms
• Transportation vehicle warning systems
• Medical equipment alert indicators

Procurement Notes

Verify the specific operating voltage and current requirements against your system design before procurement. Confirm that the surface mount footprint dimensions align with your PCB layout. Ensure the siren tone pattern meets the intended application's regulatory or operational standards. Check for any specific environmental certifications required for your deployment zone.

Selection Notes

Select this component when a combined audible and visual alarm is required in a compact form factor. The internal drive circuit simplifies integration by reducing external component count. Consider the siren waveform for maximum attention-grabbing capability in noisy environments. Verify compatibility with the available mounting space on the target enclosure or board.
