Overview
The AT-1420-ST-2-R is an externally driven electromagnetic transducer manufactured by PUI Audio, Inc. It operates at a nominal voltage of 1.5 V with a current rating of 30 mA. The device produces a sound pressure level of 80 dB at 1.5 V measured at 10 cm distance. Its resonant frequency is specified at 2.048 kHz. The unit features through-hole mounting and measures 13.8 mm in length, 12 mm in width, and 7.5 mm in depth.
Feature Summary
- Externally driven electromagnetic construction for reliable audio signaling
- Through-hole termination method for standard PCB integration
- Side port location for directed acoustic output
Applications
- Industrial control panels requiring audible status indicators
- Medical equipment alarm systems
- Consumer electronics feedback mechanisms
Procurement Notes
Verify the specific suffix designation to ensure correct voltage and mechanical configuration. Confirm that the through-hole footprint matches the target PCB layout. Check RoHS compliance status if required by project specifications. Ensure drive circuitry supports the 30 mA current requirement at 1.5 V. Validate operating temperature range against environmental conditions.
Selection Notes
Select this component when a low-voltage, high-efficiency magnetic buzzer is required for through-hole assembly. Consider the 2.048 kHz resonant frequency for tone matching. Evaluate the 80 dB SPL output against ambient noise levels. Compare dimensions against available enclosure space. Ensure the external driver can supply sufficient current without overheating.
Part Context
