PB-1820PL-06AQ

Overview

The PB-1820PL-06AQ is an externally driven magnetic transducer manufactured by Mallory Sonalert Products Inc. It operates at a rated voltage of 6 VDC with a maximum current consumption of 40 mA. The device produces an oscillation frequency between 2000 and 2500 Hz, delivering an acoustic output of 85 dB measured at 6 V and 10 cm distance. Designed for through-hole mounting via PC pins, this component serves as a fundamental audio indicator element within industrial and consumer electronic assemblies.

Feature Summary

• Externally driven magnetic transducer design
• Through-hole PC pin termination for circuit board integration
• High acoustic output efficiency relative to power consumption

Applications

• Industrial control panel indicators
• Consumer appliance status alerts
• Electronic equipment audible signaling

Procurement Notes

Verify the specific revision status against manufacturer documentation, as product change notices may indicate obsolescence or specification updates. Confirm mechanical footprint compatibility with target PCB layouts prior to ordering. Ensure drive circuitry supports the required external oscillation parameters for proper frequency generation.

Selection Notes

Select this model when an externally driven solution is required rather than an internally driven piezoelectric buzzer. This component necessitates an external oscillator source to function. Evaluate the 85 dB SPL requirement against environmental noise levels. Consider the 6 VDC rating for compatibility with existing system power rails.

Part Context

This component belongs to the broader category of audio indicators and transducers produced by Mallory Sonalert Products Inc. The company specializes in audible warning devices, including panel alarms, stack lights, and medical alert systems. The PB series represents standard magnetic transducer technology used for basic audible signaling applications across various industries.

Replacement Considerations

Official documentation indicates that the PB-1820PL-06AQ has been subject to product change notices potentially leading to obsolescence. Verify current availability status directly with the manufacturer or authorized distributors before finalizing designs.
