Overview
The PK-27A35EPDGQ is an internally driven piezoelectric buzzer with an integrated green LED indicator. It operates on a DC voltage range of 3 to 15V, drawing 18mA at the rated 12V. The device produces a continuous tone at 3.5kHz with a sound pressure level of 95dB measured at 12V and 30cm. It features panel mount installation via screw terminals and has dimensions of 36mm x 23.5mm.
Feature Summary
- Combines audible alarm with visual green LED indication
- Internally driven piezoelectric transducer for simplified circuit design
- Continuous tone output for steady state alerting
- Panel mount construction with screw terminal connections
Applications
- Industrial control panels requiring combined audio-visual alerts
- Machine status indicators in manufacturing environments
- Safety systems needing immediate operator attention signals
- Equipment monitoring stations for fault detection
Procurement Notes
Verify the specific suffix EPDGQ confirms the green LED variant and 3-15VDC operating range. Confirm panel cutout requirements match the 36mm x 23.5mm footprint. Ensure mounting hardware accommodates the screw terminal interface. Check environmental ratings against operational conditions.
Selection Notes
Select this model when both audible and visual confirmation is required in a single component. The internal drive simplifies integration by removing external driver circuits. Verify that the 95dB SPL meets regulatory noise limits for the intended location. Ensure the 3-15VDC input aligns with available system power rails.
Part Context
This part belongs to Mallory Sonalert's PK series of industrial-grade audio indicators. The series is designed for robust performance in demanding environments. The PK-27A35EPDGQ specifically integrates visual signaling capabilities alongside standard acoustic output functions.
Replacement Considerations
Direct substitutes include the PK-27A35EPDBQ for similar functionality without specified LED color details in public summaries. Verify electrical parameters and mechanical dimensions before substitution.
