Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'SR' against the manufacturer's official datasheet to confirm exact acoustic and electrical tolerances. Ensure the required operating voltage matches the 20 VDC rating to prevent damage. Confirm that the through-hole solder pin termination is compatible with the target PCB layout and assembly process.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-profile, continuous-tone indicator is required for 20 VDC systems. The 78 dBA output provides clear audibility in moderate noise environments. Consider the 23 mm footprint for mechanical clearance constraints. Verify RoHS compliance requirements if applicable to the final product assembly standards.
