AT-1224-TWT-12V-2-R

Overview

The AT-1224-TWT-12V-2-R is an electromagnetic transducer manufactured by PUI Audio, designed for through-hole PCB mounting. It operates at a rated voltage of 12 VDC with a current draw of 8 mA. The device features a round shape with a diameter of 12 mm and a height of 9 mm. It produces a continuous tone at a self-resonant frequency of 2.4 kHz with a sound pressure level of 87 dBA. The unit utilizes solder pin termination and functions within a temperature range of -30°C to +70°C.

Feature Summary

Electromagnetic transduction mechanism for audio indication
Through-hole solder pin termination for board integration
Continuous tone generation capability

Applications

Electronic equipment status indicators
Appliance alert systems
Industrial control panel signaling

Procurement Notes

Verify the specific suffix '12V' against the requested model number to ensure correct voltage rating. Confirm RoHS compliance status via the manufacturer's official documentation before finalizing procurement. Check for any REACH SVHC declarations relevant to the manufacturing region. Ensure the through-hole package dimensions match the target PCB layout constraints.

Selection Notes

Select this component when a 12 VDC supply is available and electromagnetic actuation is preferred over piezoelectric types. The 87 dBA output suits applications requiring moderate audible alerts. Verify that the 12 mm diameter and 9 mm height fit within the designated enclosure space. Consider the operating temperature range limits for the intended environmental conditions.

Part Context

This part belongs to the AT series of electromagnetic transducers from PUI Audio. It shares the standard 12 mm form factor common in this family but differs in voltage rating and acoustic output compared to variants like the 5V or 3V versions. The series is categorized under speakers and transducers for general audio indication purposes.
